Abstract:
The Río de la Plata is a large, shallow estuary located at approximately 35°S and flowing into the southwestern Atlantic Ocean. It carries a high amount of nutrients and suspended particulate matter, both organic and inorganic, to the adjacent shelf waters and is considered among the most turbid estuarine systems in the world. Knowledge of the concentration and spatial and temporal variability of these materials is critical for any biological study in the Río de la Plata. In this work, the relationship between suspended particulate matter and turbidity is empirically established in order to derive suspended particulate matter maps from satellite data (MODIS-Aqua) for the Río de la Plata region. A strong correlation between suspended particulate matter and turbidity was found (Pearson correlation coefficient =0.91) and the linear regression (slope =0.76 and intercepts =12.78, R2=0.83) explained 83% of the variance. The validation of the empirical algorithm, using co-located and coincident satellite and in situ measurements, showed good results with a low mean absolute error (14.60%) and a small and positive bias (3.04%), indicating that the estimated suspended particulate matter values tend to slightly overestimate the field values.

Abstract:
The research work presents the findings of testing air purified using two commercial air purifiers available on the local market. Tests were carried out in the office and bedroom of a residential building. The results obtained show a high (75–93%) yield of air purification from particulate matter. Particulate matters fractions such as: PM1, PM2.5, PM4.0, PM10 and total suspended particulates (TSP) were analysed by means professional dust meter. A very strong correlation of particulate matter (PM) contents were found in individual particle classes during equipment operation. Obtained results approve high efficiency of equipment operation in the total range of measured values. This study is one of the first in the topic of assessing the effectiveness of PM purification, taking into account various dust fractions. This study should be useful for individual customers and for public utilities during purchase decisions.

Abstract:
In this paper, an assessment study was performed regarding air pollution with particulate matters including submicron particles. The evaluation of the contamination level was performed at a textile production unit in Pascani, Romania, which produces polyester knitwear. In the study, automatic determinations of total suspended particulate matters (TSP), PM 10, PM 2.5, and PM 1 (particle with nominal diameter <10 µm, <2.5 µm, and <1 µm), and submicron particulate matters (0.25, 0.35, 0.50 and 0.70) were performed both outdoor, in the ambient air, and indoor (workplace) in the area of the knitting machines. The correlation between the mass concentrations of submicronic particles (µg/m 3) and the numerical concentrations (number of particles/m3) was studied, too, to establish the most appropriate expression of the air pollution level with particulate matter. The results of the performed tests showed a level of ambient air pollution with particulate matters that exceed the limit values in the case of PM 2.5 and PM 10, the total suspended particulates still falling within the limits established by law. Likewise, in the case of workplace air, the level of inhalable particulate matter (particles with nominal diameter <100 µm), the concentration is below the limit values. Regarding the way of expressing the concentration of air particles, in µg/m3 or in no. particles/m3 the tests indicated better representativeness of the pollution level if the concentration in µg m3 is expressed for the dimensional fractions with diameter ≥ 1 µm and in no. particles/m3 for particles with a diameter of ≤1 µm.

Abstract:
Environmental context Thallium occurs in the environment in two oxidation states, with TlIII being 1000-fold more toxic than TlI. We present a fractionation and speciation study of thallium in suspended particulate matter from highly polluted wastewater samples, and elucidate the dominant forms of thallium. Abstract Thallium (Tl) is a toxic element, whose toxicity is affected by its redox state. Compared with TlIII, TlI is thermodynamically more stable and less reactive; therefore in aquatic environments, dissolved thallium is mostly present as TlI. However, TlIII could be 1000 times more toxic than TlI. A combination of a fractionation and a speciation study carried out in highly polluted wastewater samples from a mining area in southern Poland in order to characterise chemical speciation of Tl in physically defined fractions is presented here. Total, particulate and dissolved thallium was determined. A leaching experiment based on forming TlIII complexed with diethylene triamine penta-acetic acid – a TlIII–DTPA complex – was performed in filters containing suspended particulate matter after single (0.45µm) and sequential filtration (15 + 0.45µm) of wastewater samples. This is the first speciation study of Tl carried out in suspended particulate matter. The results obtained indicate that the dominant form of Tl in suspended particulate matter is TlI, but TlIII could be found in suspended particulate matter fractions larger than 0.45µm.

Abstract:
This study investigates translocation of particulate carbon and nitrogen from burned and unburned catchments within New Mexico's Valles Caldera National Preserve following severe wildfire. My research questions are: (1) how much carbon and nitrogen is eroded from burned slopes and re-deposited in debris fans? and (2) how do these quantities compare to fluvial export of particulate carbon and nitrogen from nearby unburned catchments? Results indicate that the ~200 kg ha⁻¹ of nitrogen per depositional area on the debris fans represents ~50 to 100 years' worth of atmospheric inputs. In total, 124 times more carbon and 21 times more nitrogen were deposited on the two fans than was exported in particulate form from all three unburned catchments combined in water year 2012. My findings suggest that post-fire erosion may increase nitrogen loading to downslope environments, with the potential to alter the biogeochemical budgets of both aquatic and terrestrial systems.

Abstract:
Methods for the determination of Polycyclic Aromatic Hydrocarbons (PAHs) associated with suspended participate matter were developed with the aim of determining airborne concentrations and to investigate seasonal trends. Other associate pollutants such as Total Suspended Particulate matter (TSP), Particulate Matter with an equivalent aerodynamic diameter less than 10 micrometres (PM10) and lead concentration were also reviewed to determine trends. Motor vehicle emissions appear to be the source of the PAHs and differences between the types and concentrations of PAHs detected at central business district sites verses suburban sites were noted. Wind erosion, biomass burning, motor vehicle emissions and industrial processes are sources of particulate matter in the atmosphere. Lead comes mainly from motor vehicles emissions in the ACT with some lead possibly from the burning of lead contaminated fuel. TSP and lead concentrations have decreased since air quality monitoring began in the early 1980s. PM10 concentration may also have fallen but the data set for PM10s is to small to draw any firm conclusions. Only TSP lead concentrations displayed a seasonal pattern. The ACT air pollution Act 1984 has placed restriction on the burning of fuels to improve air quality in the ACT. The air quality in regards to TSP and lead is improving. However, the only strong links between the Act and decreased pollutant concentrations is the introduction of unleaded petrol and the decrease of airborne lead concentrations.

Em função da sua importância e estudos relacionados ao material em suspensão serem escassos para o carbono e nitrogênio nessas regiões. A tese é apresentada como um conjunto de capítulos interligados, nos quais foram apresentados resultados da distribuição do COP e NT nas plumas dos rios Capibaribe e Jaboatão e o arquipélago de Fernando de Noronha, com relativamente pouca influência humana, e foi escolhida como área de controle. A exportação de matéria orgânica via fluxo estuarino, ficou definida pelas medianas do Carbono Elementar de (2,04% e 0,97%) e Nitrogênio Elementar de (0,63% e 0,24%) e razão C/N de (6,60 e 9,30) nas plumas do Capibaribe e Jaboatão respectivamente. A análise de componentes principais aplicada aos dados sugeriu que os altos índices pluviométricos e o material carreado pelo fluxo fluvial para região costeira influenciaram a distribuição dessas frações e que tais diferenças podem resultar das diferentes cargas de ação antrópica e mecanismos de transporte estuário – região costeira revelando a complexidade da distribuição da matéria orgânica nestes ambientes. No segundo capítulo-artigo estudo caracterizou a matéria orgânica em função das razões elementares e isotópicas δ13C, δ15N, C/N do material particulado em suspensão na água superficial em 21 pontos amostrais sendo 12 no estuário do rio Capibaribe e 9 no estuário do rio Jaboatão. Os maiores valores de δ13C, δ15N, C/N (-17,75‰, 23,71‰ e 13,45‰) no Capibaribe e, (-21,97‰, 27,30‰ e 14,74‰) no Jaboatão, respectivamente. Os valores encontrados sugerem que uma grande parte da matéria em suspensão dos rios em estudo, se origina a partir de entradas de efluentes com alto teor de matéria orgânica, como também que a MO exportada pelos rios é fortemente influenciada pelo seu elevado estado de eutrofização, com acentuada produção autóctone. Nos estuários superiores os valores empobrecidos de 13C indicam maior presença de material tanto de origem continental quanto de origem mista. É também observado que δ13C e a razão C/N não são correlacionados no estuário do Capibaribe e estes resultados sugerem que existem áreas no estuário de preferência, fontes de matéria orgânica sob a influência tanto de autóctones (estuário inferior) como de alóctones (estuário superior). O terceiro e último capítulo - artigo ocorreu na região costeira de PE e foram agregadas as frações COP e NT à fração de COD, as quais não apresentaram correlação, indicando que elas não tenham a mesma fonte, destacando a influência alóctone para o aumento dessas frações e assim os efeitos de influencia do rio Capibaribe nas águas oligotróficas costeiras.<br>The main objective of this thesis is to add information to the existing knowledge of the organic fraction of suspended matter in the oceanic-coastal-estuarine region of the coast of Pernambuco, Brazil and the adjacent coastal zone, mainly in regard to its concentrations, by evaluating the distribution of POC and NT. In spite of the importance of this topic, studies on suspended matter for carbon and nitrogen are scarce in these regions. The thesis is presented as a set of interrelated chapters that contain the results of POC and NT distribution in the plumes of rivers Capibaribe and Jaboatão. The Fernando de Noronha Archipelago was chosen as a control area because of the minimal human influence in this region. The export of organic matter through estuarine flow was defined using the medians of elemental carbon (2.04% and 0.97%) and elemental nitrogen (0.63% and 0.24%), and C/N ratio (6.60 and 9.30) in the Capibaribe and Jaboatão plumes, respectively. The principal component analysis applied to the data suggests that the high rainfall and the matter carried by the river flow to the coastal region influence the distribution of these fractions. The analysis also suggests that the detected differences can be caused by different charges of human action and estuarycoastal mechanisms of transport, thus revealing the complexity of the distribution of organic matter in these environments. In the second chapter of the article, organic matter was characterised on the basis of elementary and isotopic ratios δ13C, δ15N, and C/N of the suspended particulate matter in surface water at 21 sampling points, of which 12 were in the estuary of river Capibaribe and 9 in the estuary of river Jaboatão. The highest values of δ13C, δ15N, and C/N (-17.75‰, 23.71‰, and 13.45 ‰) in Capibaribe and (-21.97‰, 27.30‰, and 14.74 ‰) in Jaboatao, respectively. The values found in this study suggest that a large proportion of suspended matter from the rivers originates from effluent inputs with high organic matter content. Also, the OM exported by the rivers is heavily influenced by a high state of eutrophication, with pronounced autochthonous production. In the upper estuary, the impoverished values of δ13C indicate a greater presence of matter of continental origin and of mixed origin. It was also observed that δ13C and C/N ratio are not correlated in the estuary of the Capibaribe, which suggests that there are areas at the estuary of preference where sources of organic matter are under the influence of autochthonous (lower estuary) or allochthonous (upper estuary) contributions. The third and final chapter-article occurred in the coastal zone of PE. Here, the fractions of POC and NT were added to the fraction of DOC and showed no correlation, which indicates that they do not share the same source. Moreover, this finding highlights the influence of allochthonous contributions to the increase of these fractions and the consequent effects of the influence of Capibaribe river in coastal oligotrophic waters.

Abstract:
Foram abordadas questões relacionadas com a temática da poluição atmosférica provocada pelo material particulado em suspensão. Dois ambientes foram selecionados para estudo: um ambiente de mineração e um ambiente urbano. Com o objetivo de obter uma avaliação preliminar da qualidade do ar nesses ambientes, foi realizado um programa de amostragem para cada área. Dois pontos básicos foram abordados nessa avaliação: a determinação da concentração de partículas totais em suspensão e a caracterização química e física do material particulado. A determinação das concentrações de partículas totais em suspensão foi obtida através do uso de amostradores de grande volume (Hi-vols). O método de referência utilizado foi o método do amostrador de grande volume proposto pela ABNT através da norma NBR 9547: 97. A caracterização física envolveu a determinação da distribuição granulométrica do material particulado em suspensão enquanto que a caracterização química compreendeu a determinação da sua composição. As técnicas analíticas utilizadas na caracterização do material particulado, foram a espectrometria de Fluorescência de Raios-X (XRF) para a caracterização química, e o Espalhamento de Luz Laser de Baixo Angulo (LALLS) para a caracterização física. Com relação às concentrações de partículas totais em suspensão, os resultados indicaram que as áreas de mineração apresentaram valores superiores aos encontrados na área urbana, inclusive com ultrapassagens dos padrões legais, fato este que não ocorreu na área urbana estudada. Para a distribuição granulométrica do material particulado, os resultados demonstraram que as frações mais finas do particulado apresentaram-se em maiores quantidades nas áreas de mineração, enquanto que as frações mais grosseiras apresentaram-se em maior quantidade na área urbana. Quanto à composição química do material particulado em suspensão, podemos concluir que para as áreas de mineração, esta foi muito semelhante à da rocha lavrada.<br>Atmospheric pollution aspects were analyzed. Two types of ambients were selected for study: a mining ambient and an urban ambient. To obtain a preliminary evaluation of the quality of the air in these ambients a sampling program was accomplished for each area. Two basic points were studied: the concentration of the total suspended particulates and the chemical and physical characterization of the particulate matter. The concentrations of total suspended particulates were obtained through the use of high volume samplers (Hi-vols). The reference method used was the high volume sampler method, proposed by ABNT through the norm NBR 9547: 97. The physical characterization involved the determination of the size distribution of the suspended particulate matter while the chemical characterization involved the determination of its composition. The analytic techniques used for the characterization of the particulate matter were the X-Ray Fluorescence (XRF) for the chemical characterization, and the Low Angle Laser Light Scattering (LALLS) for the physical characterization. Concentration levels for total suspended particulates showed that the mining areas presented higher values than those for urban area. Legal standards were exceeded in the mining area, fact that did not occur in the urban area. Size distributions of the particulate matter demonstrated that the finest fractions were found in larger amounts in the mining areas, while the coarses fractions were present in larger amounts in the urban area. The chemical compositions of the suspended particulate matter in the mining areas were very similar to the compositions of the rocks been mined.

Abstract:
Transport of suspended particulate matter (SPM) plays a vital role in controlling large-scale processes related to geophysical flows such as dispersal and sinking of organic matter and contaminants to offshore and deep waters, nutrient cycles, food web stability, morphodynamics and sedimentation in both limnetic and pelagic ecosystems. Although it has been recognized that small-scale microbial processes can introduce substantial differences to the way in which SPM moves in natural waters, the extent to which the attached biological matter affects SPM dynamics is still not well characterized. This thesis focuses on quantifying the attached biomass fraction on SPM aggregates and investigating its contribution to SPM flocculation dynamics, which consequently control SPM aggregate geometrical properties and transport. A novel laboratory-based Optical Measurement of Cell Colonization (OMCEC) system and a microbiological-physical model (BFLOC2) are the main achievements of this thesis that allow the analyses of the correlations between environmental conditions, aggregate-attached biomass fraction, cell colonization patterns, aggregate size, fractal dimension and settling velocity. OMCEC is an experimental system that can simultaneously measure the material composition, geometric properties, and motion of individual suspended aggregates in a non-invasive and non-destructive way. OMCEC consists of a full-color high-resolution optical system and real-time algorithms for (i) material segmentation based on light spectra emission analysis, (ii) quantification of various geometrical properties, and (iii) motion detection with micro particle tracking velocimetry (μPTV). OMCEC was applied herein on three types of aggregates: cell-associated minerals, cell-associated microplastics, and three-phase aggregates made of minerals, microplastics, and biological matter. OMCEC application on Saccharomyces cerevisiae-colonized minerals at four sucrose concentrations showed the likelihood of cell colonization to increase with increasing nutrient concentration. The attached biomass fraction was found to increase nonlinearly regarding an increase of aggregate size but almost constant with fractal dimension variation. Cell distribution on mineral surfaces was then analyzed and classified into three colonization patterns: (i) scattered, (ii) well-touched, and (iii) poorly-touched, with the second being predominant. Cell clusters in the well-touched pattern were found to have lower fractal dimension than those in the other patterns. A strong correlation of colonization patterns with aggregate biomass fraction and properties suggests dynamic colonization mechanisms from cell attachment to minerals, to joining of isolated cell clusters, and finally cell growth over the entire aggregate. OMCEC application on microplastics (MPs) being colonized by natural biological matter from Hawkesbury River, NSW, Australia demonstrated that the biomass fraction of MP aggregates has substantial control over their size, shape and, most importantly, their settling velocity. Polyurethane MP aggregates made of 80% biological matter had an average size almost double that of MP aggregates containing 5% biological matter and sank two times slower. Based on our experimental data, we introduce a settling velocity equation that accounts for the shape irregularity and fractal structure of MP aggregates. This equation can capture the settling velocity of both virgin MPs and cell-associated MP aggregates with 7% error and can be applied widely to predict the settling flux of MP aggregates made of different polymers and various types of biological matter. To consider the complex genesis of cell-associated mineral aggregates, the BFLOC2 model was introduced to predict aggregate geometry and settling velocity under simultaneous effects of hydrodynamic and biological processes. While minerals can contribute to aggregate dynamics through collision, aggregation, and breakup, living microorganisms can colonize and establish food web interactions that involve growth and grazing, and modify the aggregate structure. Modeling of cell-associated mineral aggregate dynamics over a wide range of environmental conditions showed that maximum aggregate size, biomass fraction, and settling velocity could occur at different optimal environmental conditions. Unlike mineral aggregates, which have maximum size when shear rates tend to zero, a relative maximum size of cell-associated mineral aggregates can be reached at intermediate shear rates as a result of microbiological processes. The settling velocity was ultimately controlled by aggregate size, fractal dimension, and biomass fraction. The innovative aspect of this thesis is the simultaneous quantification of composition, architecture, and settling velocity of individual aggregates. Therefore, it puts forth the analysis and prediction of cell colonization impacts on dynamics and transport of suspended particulate matter in natural waters. The output of this thesis can be used in natural water monitoring programs to estimate the biological content based on SPM size, capacity dimension, and settling velocity, which can be measured using in-situ methods. Furthermore, the evidence and tools to quantify the sinking and floating of microplastic subjected to bio-fouling can be implemented in microplastics transport models to enable the three-dimension modeling of both low- and high-density microplastics. The BFLOC2 model can be coupled to traditional sediment transport models to better describe the sediment formation dynamics, thus giving a more precise prediction of sedimentation and carbon flux to deep waters and offshore.

Abstract:
A field filtration method for the concentration and separation of suspended particulate matter (SPM) from freshwater systems and the subsequent determination of major, minor, trace and ultra trace elements (Al, As, Ba, Be, Ca, Cd, Co, Cr, Cs, Cu, Fe, Ga, Hf, K, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, Rb, S, Sb, Sc, Si, Sn, Sr, Ta, Th, Ti, Tl, U, V, W, Zn and Zr) is validated with respect to detection limits, precision, and bias. The validation comprises the whole procedure including filtration, sample digestion and instrumental analysis. The method includes two digestion procedures (microwave acid digestion and alkali fusion) in combination with inductively coupled plasma atomic emission spectrometry (ICP-AES) and inductively coupled plasma quadrupole mass spectrometry (ICP-QMS). Total concentrations of these 38 trace and major elements have been determined in suspended particulate matter (SPM) from lake and river water with low levels of suspended solids (<2 mg l-1 DW), and a wide range of element concentrations. The precision of the method including filtration, digestion and instrumental determination ranges between 8 and 18% RSD for most elements on a dry weight basis. Higher recovery after acid digestion is found for some elements, probably because of volatilization or retention losses in the fusion procedure. Other elements show higher recovery after fusion, which is explained by more efficient decomposition of mineral phases relative to the non-total acid digestion. Non-detectable concentrations of some elements are reported due to small differences between blank filter levels and the amounts of elements present on the filters after sampling. The calculated sums of main inorganic components, expressed as oxides, ranges between 94.0 and 98.0% ash weight. The method limits of detection range between 0.7 ng and 100 µg, as estimated from the blank filter samples. These detection limits are 3-1000 times higher compared to the corresponding instrumental limits of detection. The accuracy and bias of the overall analytical procedure was assessed from replicate analysis of certified reference materials. A better knowledge of the mechanisms of filter clogging in sampling of suspended matter is important in order to extend the applicability of the method. For the sample types investigated in this study, the amount of inorganic material in the suspended particulate matter (SPM) seems to be the most important factor controlling the maximum volume of filterable water, and Fe is presumable the most important clogging regulating parameter in the group of elements included in the inorganic matter. A critical evaluation of the instrumental capabilities of the ICP- QMS instrumentation in comparison with the sensitive double focusing sector field plasma mass spectrometry technique (ICP-SFMS) is also included. It was found that a modified microwave acid digestion procedure in combination with ICP-SFMS could replace ICP-AES determinations and fusion digestions for most of the investigated elements. Guidelines and limitations for this powerful and relatively simple and less time consuming procedure, covering most elements in one single determination, are discussed.<br>Godkänd; 2004; 20070126 (ysko)

Abstract:
Assessment of non-carcinogenic risk for the child population health from chemical substances taken with the motor vehicle exhaust gases in 4 districts of the city of Kazan based on the monitoring data from FSFHI �The Center of Hygiene and Epidemiology in the Republic of Tatarstan� for the period from 2015 to 2021 was carried out. The average annual concentrations of chemical substances exceeded the allowable level of standards (MAC) from 2.32 to 9.96 of MAC in all zones. The value of the total daily dose on the inhalation route of the substances� intake with atmospheric air (I) made 1.09 � 10.33 mg/(kg x day) depending on the zone. An unacceptable level of non-carcinogenic risk (HI&gt;3.0) was determined in all zones. In zones 2 and 4, the major impact on the RS was made by soot (HI 13.1), in zone 1 � by complex intake of all fractions of suspended particulate matters, with maximal level of PM 2,5 (HI =5.98), in zone 3 � by intake of �� 10 (HI 7.83). Black carbon (�C) was found to be an important indicator, as well as PM 2,5 and PM 10, for assessing the road traffic impact on the air quality and health. The children living in zones 2 and 4 are most vulnerable to non-carcinogenic risk as far as the respiratory system, which is formed due to complex intake of �C, �� 10 and �� 2,5. Transition to a complex assessment of risk from chemical substances with the account of contribution of certain substances is an important decision in determining the priority actions for minimizing the children�s health risk at regional level.

Abstract Stabilizing colloidal suspensions helps prevent scale deposition and inorganic particulate matter fouling in aqueous systems. Colloidal suspension stabilization was modeled using iron oxide (Fe2O3) suspensions in synthetic tap water containing a mixed electrolyte system that included a variety of ions interacting with suspended particles. Zeta potential measurements of suspended particles were conducted over a wide pH range (3.5 to 10) both in the absence and in the presence of deposit control polymers (DCPs). Results suggest that both polymer functional group type(s) and molecular weight (MW) impact dispersion efficiency.

Abstract:
The aim of this research to determine particle pollution in the University of Baghdad campus. This study was chosen as a result of the University of Baghdad’s location being close to sources of particulate pollution, such as the Doura refinery and traffic intersections that are crowded most of the time, as well as the frequent use of cars by university students and employees. Air samples were collected via portable particle mass counter device (Temtop) used to determine concentrations of total suspended particles TSP and particulate matters |PM (PM2.5 and PM10). Readings conducted in the first half of 2024 during day. Particulates matters including PM with different diameters such as particulate matter 2.5 PM2.5 μg/m3 and particulate matter 10 PM10 μg/m3 , and larger suspended particles matters in air TSP μg/m3 during the study periods which extend from January to June 2024. The largest concentration value of PM2.5 was founded in January was 48.3 μg/m3 while the lowest one recorded in June was 14 μg/m3 . As well as concentrations of PM10 ranged from 74.9 μg /m3 in January to 15 μg /m3 in February, TSP recorded value found between 7197 and 1740 μg /m3 in January and February respectively. The averages of particulate matters and total suspended particles matters in some months were exceeded WHO suggested standards for ambient and in others months within WHO standards. This may be resulted due to the existence of relevant industries and crowded traffic around the campus that led to high concentrations. Therefore, effective strategies such as traffic management, industrial movement away from university can be effective in reducing airborne PM and TSP concentrations.

Abstract:
The aim of this study is to develop a new air cleaning method being applicable to suspended particulate matters (SPM) of wide sizes. We experimentally studied about the effects of a humidity swing operation where sample air is continuously humidified with heating and dehumidified with cooling. The total of SPM concentration of sample air decreased with the humidity swing operation; however, the concentration of SPM from 0.3 to 1 μm markedly increased. Suction flow accompanying condensation, cohesion and thermophoresis were considered as the SPM reduction effects. It would appear that the nano-size SPM grew to submicron size by nuclear condensation and submicron size SPM increased. The experimental results showed that the SPM concentration of 0.3 μm or less decreased by 89% and the total of that decreased by 80%. The applicability of the humidity swing operation to removal of SPM including nano size SPM was shown by the results. Also, exponential reduction of the SPM concentration was demonstrated with applying the repeated humidity swing operation in a circulation air-cleaning apparatus. This method is expected to become effective air cleaning method applicable to wide size range of SPM.

Abstract:
SPM (suspended particulate matters) removal effects of a humidity swing operation where sample air is continuously humidified with heating and dehumidified with cooling were experimentally studied. The experimental results showed that the humidity swing operation reduced SPM ranging from nanometer to micrometer sizes due to multiple phenomena such as suction flow accompanying condensation and thermophoresis, and the total SPM concentration decreased by 80% under the maximum humidity swing condition. The removal mechanisms were theoretically estimated. It was estimated that contributions of the suction and thermophoresis are significant, gravitational sedimentation works above 5 μm size, and the effect of inertial collision is insignificant. Nuclear condensation that markedly changes the SPM size distribution would not be an effective SPM removal effect. The sum of the theoretical estimations is smaller than the experimental result, and study for clarifying the removal mechanisms is necessary. It was also experimentally confirmed that the SPM reduction effects have no dependence on the concentration. The SPM removal experiment in a circulating system was also conducted. With repeatedly applying the humidity swing operation, the SPM concentration for whole size ranges exponentially decreased and converged at certain value. SPM generation by a mechanical pump might occur. With improving the apparatus, this method is expected to become an effective SPM removal method applicable for the SPM from nanometer to micrometer size.

Abstract:
Abstract Drilling mud is a slurry comprising oil, water, and chemical additives. Mud is critical to drilling a modern well as it is circulated down a wellbore to remove rock cuttings and to power the drill bit. A significant volume of this drilling mud is used and later recirculated. The drilling mud warms at depth, creating steam, which holds suspended PM and dissolved chemicals. Many of the pieces of equipment are open or only partially enclosed, allowing for steam generation, while other processes generate aerosolised sprays. There is a significant potential for petroleum workers to become exposed and potentially suffer health effects because of drilling mud exposure. This study aims to find the major sources of PM10 on petroleum wells and quantify the levels of exposure and health hazard associated with drilling mud on petroleum rigs. A literature search was performed, which included all available materials which contained static or mobile concentrations of PM10 or oil mist within the UK or international petroleum drilling sites with a preference for North Sea operations. The study predicts the total PM10 by estimating the combined impact of both solid PM and oil mist. Using this conversion, it is also possible to estimate PM10 concentrations when using water-based muds. The work designates and discusses the expected health ramifications of excess exposure. A quantitative assessment of the risk of silicosis 15 years post-exposure is also calculated, predicting dire consequences to petroleum personnel in the long term. The exposure assessment methods, hygienic standards, and preventive measures are also addressed briefly.

Abstract:
The San Joaquin Valley is identified as an area with a high level of particulate matter (PM) in the air, reaching above the federal and state clean air standards (EPA 2019). Many of the cities in the valley are classified as the most polluted cities in the United States for both particulate matter and ozone pollution (American Lung Association, 2021). To resolve this issue, alternative forms of transportation have been considered in transportation planning. In this study, active transportation mode air quality was monitored on selected Woodward Park and Old Clovis trails and urban bike lanes. Real-time aerosol monitors, and low-cost sensors were carried in a backpack on bicycles during the sampling. Researchers collected GPS data via a portable GPS technology called Tracksticks. Driving transportation mode air quality data was acquired from the roadways within the Fresno/Clovis area, spanning six sampling routes, and during intercity trips between Fresno, Berkeley, and Los Angeles, for a total of five sampling routes. ‘On-Road' (outside vehicle) monitors were installed on the roof of a vehicle while ‘In-Vehicle’ monitors were installed inside the vehicle for comparison with the particulate pollution levels in the two contrasting microenvironments. The results showed the following three main outcomes: (1) clear relationships exist among PMs of different sizes; (2) there were greater variations in air quality of bike trails and On-Road samples than backyard and In-Vehicle samples; (3) we observed significant differences in air quality inside and outside the vehicle while driving local and intercity roadways; and (4) the road trip to the Bay area revealed that San Joaquin Valley has increased ambient PM2.5 and black carbon (BC) levels compared to those in the Bay Area on every trip, regardless of the daily change of the air quality.

Abstract:
Vegetation fires are common in South/Southeast Asian (SA/SEA) countries. However, few studies focused on vegetation fires and the changes during COVID compared to pre‑pandemic. This study fills an information gap and reports total fire incidences, total burnt area, type of vegetation burnt, and total particulate matter emission variations. Results from the short‑term 2020‑COVID versus 2019‑non‑COVID year showed a decline in fire counts varying from -2.88 to 79.43%. The exceptions in South Asia include Afghanistan and Sri Lanka, and Cambodia and Myanmar in Southeast Asia. The burnt area decline for 2020 compared to 2019 varied from -0.8% to 92% for South/Southeast Asian countries, with most burning in agricultural landscapes than forests. Several patches in S/SEA showed a decrease in fires for the 2020 pandemic year compared to long term 2012–2020 pre‑pandemic record, with Z scores greater or less than two denoting statistical significance. However, on a country scale, the results were not statistically significant in both S/SEA, with Z scores ranging from -0.24 to -1, although most countries experienced a decrease in fire counts. The study highlights variations in fires and emissions useful for fire management and mitigation.
