Abstract:
Abstract Good air quality in poultry houses is crucial for animal health and productivity. In these houses, air is generally contaminated with noxious gases and microorganisms, the concentrations of which depend on numerous factors including microclimate. In this case study, the relation between microclimate and air concentrations of noxious gases and microorganisms was investigated in extensively reared turkey house. The study was carried out at a family household in Dalmatia hinterland, Croatia, with 50.3±3.1 turkeys kept in the house during the study period. Air temperature, relative humidity, airflow rate, concentrations of ammonia, carbon dioxide, bacteria and fungi in indoor air were measured three times per month from September to December, in the morning, prior to releasing turkeys out for grazing. Air temperature ranged from 9.73 to 26.98 °C, relative humidity from 63.29% to 75.08%, and airflow rate from 0.11 to 0.17 m/s. Lowest ammonia and carbon dioxide concentrations were measured in September (2.17 ppm and 550 ppm, respectively) and highest in December (4.50 ppm and 900 ppm, respectively). Bacterial and fungal counts were lowest in December (2.51×105 CFU/m3 and 3.27×103 CFU/m3 air, respectively) and highest in September (6.85×105 CFU/m3 and 1.06x105 CFU/m3 air, respectively). Air temperature and relative humidity showed negative correlation with concentrations of noxious gases and positive correlation with air microorganisms (P<0.05 all).

Abstract:
The proliferation of harmful gases is a major global problem caused by anthropogenic activities. This study hypothesized that the emission of noxious gases varies seasonally in indoor and outdoor environments. Air samples were collected from 40 georeferenced residential areas ( N = 40) in Port Harcourt using Aeroqual 500 monitor to measure six gases: CH4, CO, NH4, NO2, O3, and SO2. Samples were collected at different times, locations, and seasons. The analysis of variance (ANOVA) indicates a significant difference in concentration between gases, times, and locations at p < 0.001. But the interaction effect shows that times and seasons significantly affect noxious gas concentration compared to location. In general, the concentration of CO was the highest, while that of O3 was the lowest. The order of concentration is CO > SO2 > NO2 > CH4 > NH4 > O3. The concentrations of NO2 and SO2 were higher than the WHO limit, while CO, CH4, NH, and O3 were below the WHO limit. Furthermore, CO concentration was highest in the morning, while NO2 and SO2 concentrations were highest in the evening. For seasons, the CH4, NH4, NO2, and SO2 were higher during the dry season, while CO concentration was higher during the wet season. Pollutant levels should be regularly monitored to help provide exposure advisory to city dwellers on the impact of atmospheric pollution on their health.

Abstract:
Animal welfare is a matter of increasing interest due to ethical and economical worries regarding animal rights and the sustainability of meat production. Ammonia, carbon dioxide, and methane can be produced in the livestock buildings and, if not adequately controlled by ventilation, can be dangerous for animals and farmers. The aim of the present paper is to study the effects of different ventilation systems in rabbit buildings based on the temporal patterns and the spatial distribution of these noxious gases. The experimental measurements were conducted in two rabbit farms with genetically homogeneous animals subjected to the same diet. Two buildings with different forced ventilation layouts (cross ventilation - building A and longitudinal ventilation - building B) were subjected to the monitoring of indoor environmental conditions (temperature, relative humidity, ammonia, carbon dioxide, methane) over a whole year. In both the buildings, ventilation was adjusted automatically by means of electronic control units, which were controlled by temperature sensors, located at the centre of the buildings. Gas concentrations inside the buildings followed clearly defined sinusoidal patterns on a daily basis with the highest values reached in winter during the morning hours for ammonia and during the night hours for carbon dioxide and methane. In particular, ammonia revealed a maximum concentration of 30.7 mg m–3 in building A (cross ventilation) and 12.9 mg m–3 in building B (longitudinal ventilation), whereas the minimum values were 6.0 and 4.2 mg m–3, in building A and B, respectively. As a consequence, daily mean concentrations of noxious gases, solely could not be considered representative of the actual conditions of air quality in the buildings. The airflow direction clearly influenced the spatial concentration of ammonia, which showed different patterns in the two buildings. In building A, the highest ammonia concentration was in a diffuse central area, whereas in building B, it was determined to be less extended and located in the proximity of the wall equipped with extraction fans. The results of this study provide important indications for the planning and management of housing systems for rabbits including: the correct positioning of gas sensors for regulating ventilation systems must be central in case of cross ventilation, but close to the suction fans in case of longitudinal ventilation; the cross ventilation can lead to ammonia concentration higher than longitudinal ventilation, which is caused by the close and prolonged contact of airflow with manure surface in the channels; fans for longitudinal ventilation must be positioned in the same side of the building where scrapers discharge manure; furthermore, manure scraping has to be performed daily in winter during the hours of the day when ventilation rate is at its maximum.

Abstract:
In the case of the MAG welding of carbon and low-alloyed steels wires or hollow wires with (rutilic or basic) flux with metallic powder or self-protection are used. In indoors weldings huge quantities of smoke, gases, dust and particles in suspension, etc. get accumulated. These noxious substances produced during the welding process may severely affect the welders health. To improve the welders working conditions, on an international scale, the following are used: welding masks with self-obscurazation and air control; noxious substances vacuum cleaners fitted with filters; MAG welding pistols with gase and smoke absorbing devices. For the improvement of the welders working conditions, producers of welding materials invented hollow wires with (rutilic flux or with metallic powder) with a smoke-reduced emission [1,2,3,4,5].

Abstract:
AbstractThe use of coal, as either a primary energy source or as a source of feedstock chemicals, has been complicated by the noxious and toxic chemical species formed in its gaseous effluents and also by the huge quantities of ash vhich result from its processing. Both the noxious gases and the ash have been the subjects of Federal legislations.X-ray powder patterns (XRPP), composed of atom-pair and self x~ray scattering and the diffraction produced by crystalline phases, have long been used to investigate coals and particularly their combustion ashes (1-3). Over twenty different crystalline phases have recently been reported to exist in certain lignite fly ash (3). Analysis of the crystalline phases has typically been emphasized in previous papers involving coals and ashes, but the amorphous scattering has been given little treatment.

Abstract:
For the examination of noxious emissions, cladding tests were performed according to EN ISO 6847. The filler materials were 1.2 mm diameter wire-electrodes, made of tin bronze, aluminium bronze, austenitic stainless steel, duplex stainless steel and nickel alloy.The low-energy metal transfer welding process, named CMT (cold metal transfer) was examined, on the welding source type Trans Puls Synergic 2700 CMT, of 270 A, produced by the company Fronius, Austria. For sampling welding smoke particles, an Apex type pump was used. For measuring the concentration of gases emitted by welding, a Triple Plus type multi-gas detector was applied.The particulate emission rate is 0.500 mg / m3 in the breathing zone, according to ISO 10882-1. For comparison, the measured emission rate is from 0.877 to 2.513 mg / m3 in the welding zone, according to ISO 15011-1. The concentration of the emitted gases is in the ranges: 0.14 to 0.16% CO2; 0.1-0.2 ppm NO2; 0-15 ppm H2; 0-5 ppm CO. These concentration levels are below the exposure limits (8 hours per day, five days a week): 5% CO2; 1.0 ppm NO2; 30 ppm CO. In conclusion, the emissions from the CMT welding process are without health risk for the welder.

Abstract:
The occupational risk assessment of a machine building company must cover each activity and workstation, taking into account each component of the production system (work system), each workload, work equipment and the work environment. This assessment is an extremely complicated and complex issue since the production system of such an enterprise is particularly complex and complicated. Welding assembly is a highly polluting technology process, especially of the atmosphere and soil. The formation of gases in the welding process is the result of burning of the electrodes, powders, forming the molten metal bath and making the weld seam. Welding operators are exposed to smoke and toxic gases resulting from the welding process, which can in many cases be hazardous to health. Many acute intoxications that may be caused by excessive exposure to or short exposure to smoke and gas resulting from the welding process have been studied over time. In the paper are presented the elements of risk related to the welding process and the most widespread occupational diseases that can occur in the ranges of the welding operators. The following are presented the noxious emissions from welding and are determined by a practical method the emission of noxious at welding deposition of a welding sample, using the manual arc welding process with coated electrode.

The present paper refers to the remelting of light waste. The research aims to provide a substantial decrease of the oxidation losses and a decrease of the noxious expulsion resulting from the production of aluminium alloys. The fundamental solution found consists in achieving a stable flux layer. For this the wastes are introduced directly in the metallic bath, without a previous preparation. Data about oxidation losses, the content of gases and the correlation between the casting properties and the quality of remelting secondary alloys are presented. Several samples are analysed in order to point out the quality of the alloy and the relationship between the chemical composition, the content of gases and the free linear contraction of the alloy.

Chronic obstructive pulmonary disease, namely, pulmonary emphysema and chronic bronchitis, is a chronic inflammatory response of the airways to noxious particles or gases, with resulting pathological and pathophysiological changes in the lung. The main pathophysiological aspects of the disease are airflow obstruction and hyperinflation. The mechanical properties of the respiratory system and its component parts are studied by determining the corresponding volume-pressure (P-V) relationships. The consequences of the inflammatory response on the lung structure and function are depicted on the volume-pressure relationships.

Abstract:
Leaf samples of Cryptomeria japonica D. Don (and some other conifers) taken from various locations in Japan were analyzed for differences in the amount and elemental composition of their epicuticular wax. In C. japonica the amount of wax per unit leaf mass was lower, and the C content of the wax relatively higher, than those of other species. The properties of the wax (amount, C and O contents) varied according to natural environmental factors such as altitude and exposure to volcanic acidic gases such as H2S, as well as branch height and leaf age within the tree. The amount of wax increased with leaf age (during the growing phase), altitude, branch height, and exposure to the gases, while the C content of wax decreased and the O content increased, except in the case of altitude, where they showed an opposite change. These findings suggest different alterations in wax properties under the effects of water stress (on high branches and at locations with a low rain factor), exposure to noxious gases, and strong UV radiation at high altitude.

Abstract:
Chronic obstructive pulmonary disease (COPD) is a chronic, progressive lung disease resulting from exposure to cigarette smoke, noxious gases, particulate matter, and air pollutants. COPD is exacerbated by acute inflammatory insults such as lung infections (viral and bacterial) and air pollutants which further accelerate the steady decline in lung function. The chronic inflammatory process in the lung contributes to the extrapulmonary manifestations of COPD which are predominantly cardiovascular in nature. Here we review the significant burden of cardiovascular disease in COPD and discuss the clinical and pathological links between acute exacerbations of COPD and cardiovascular disease.

Abstract:
The POM/TiO2/SiO2 Supermolecule composite based on POM films were synthesized via an easy liquid phase deposition method (LPD) at low processing temperature for the first time and employed for studying the charge transfer processes between the film and ambient atmospheres. Here the POM is the Keggin type lacunary FeW11O399- (FeW11) polyanion. Gaseous adsorption properties of the films to noxious gases such as NH3 show that the composite is much better than that of the TiO2/SiO2 films, which may be attributed to the enhancement of the gaseous adsorption ability on the film surface as well as the modified charge transfer process between the adsorbed gases and the films due to the inducing of POM into TiO2/SiO2 matrix. In addition, more importantly, compared with the TiO2/SiO2 films, the POM/TiO2/SiO2 films showed relative faster response and recovery time at optimal working temperature of 440 K, indicating that the films have great potential to be designed as gas sensor used at low temperature.

Abstract:
Microelectronic gas-sensor devices were developed for the detection of carbon monoxide (CO), nitrogen dioxides (NO2), ammonia (NH3) and formaldehyde (HCHO), and their gas-sensing characteristics in six different binary gas systems were examined using pattern-recognition methods. Four nanosized gas-sensing materials for these target gases, i.e., Pd-SnO2 for CO, In2O3 for NOX, Ru-WO3 for NH3, and SnO2-ZnO for HCHO, were synthesized using a sol-gel method, and sensor devices were fabricated using a microsensor platform. Principal component analysis of the experimental data from the microelectromechanical systems gas-sensor arrays under exposure to single gases and their mixtures indicated that identification of each individual gas in the mixture was successful. Additionally, the gas-sensing behavior toward the mixed gas indicated that the traditional adsorption and desorption mechanism of the n-type metal oxide semiconductor (MOS) governs the sensing mechanism of the mixed gas systems.

Abstract:
To date, three main gasotransmitters, that is, hydrogen sulfide (H2S), carbon monoxide (CO), and nitric oxide (NO), have been discovered to play major bodily physiological roles. These gasotransmitters have multiple functional roles in the body including physiologic and pathologic functions with respect to the cellular or tissue quantities of these gases. Gasotransmitters were originally known to have only detrimental and noxious effects in the body but that notion has much changed with years; vast studies demonstrated that these gasotransmitters are precisely involved in the normal physiological functioning of the body. From neuromodulation, oxidative stress subjugation, and cardiovascular tone regulation to immunomodulation, these gases perform critical roles, which, should they deviate from the norm, can trigger the genesis of a number of neurodegenerative diseases such as Alzheimer’s disease (AD) and Parkinson’s disease (PD). The purpose of this review is to discuss at great length physical and chemical properties and physiological actions of H2S, NO, and CO as well as shedding light on recently researched molecular targets. We particularly put emphasis on the roles in neuronal inflammation and neurodegeneration and neuronal repair.

Abstract:
Alleviating the increasingly critical environmental pollution problems entails the sensing of volatile organic compounds (VOCs) as a hazardous factor for human health wherein the development of gas sensor platforms offers an efficient strategy to detect such noxious gases. Nanomaterials, particularly carbon-based nanocomposites, are desired sensing compounds for gas detection owing to their unique properties, namely a facile and affordable synthesis process, high surface area, great selectivity, and possibility of working at room temperature. To achieve that objective, g-C3N4 (graphitic carbon nitride) was prepared from urea deploying simple heating. The ensuing porous nanosheets of g-C3N4 were utilized as a substrate for loading Au nanoparticles, which were synthesized by the laser ablation method. g-C3N4 presented a sensing sensitivity toward organic vapors, namely methanol, ethanol, and acetone vapor gases, which were significantly augmented in the presence of Au nanoparticles. Specifically, the as-prepared nanocomposite performed well with regard to the sensing of methanol vapor gas and offers a unique strategy and highly promising sensing compound for electronic and electrochemical applications.

Abstract:
Chronic Obstructive Pulmonary Disease is characterized as a progressive and irreversible inflammatory response in the airways and alveoli because of exposure to noxious particles or gases. Excessive inflammation causes progressive, persistent, and not fully reversible structural changes and airflow limitation. Although COPD is a significant public health problem, diagnosis and treatment stages need to be improved.Nocturnal Noninvasive Positive Pressure Ventilation is one of the treatment modalities of choice for COPD exacerbation, and the role and benefits of NPPV in COPD exacerbation are well defined, but the use of nocturnal NPPV on stable severe COPD individuals is controversial, and the evidence is not sufficient yet. This review evaluates the effects of nocturnal NPPV on stable COPD patients.

Many of that have used up to present depend of its installation, usage and maintenance costs. For the mentioned above 25 years of emissions decreasing ways practical using on the vessels has identified it further usage consistency and profitability (efficiency).

СО and СО2 emissions decreasing is a corner task, as a fuel oil quality and lower calorific value are identified by the carbon & hydrogen content. Thus the fuel oil carbon and hydrogen content decreasing will bring to the decreasing of a quality and lower calorific value. Therefore all of this 25 years for the vessels diesel engines (ICE) exhaust gases СО & СО2 emissions decreasing the energy efficiency task is stated. Our proposed way can allow to resolve the СО & СО2 emissions decreasing task for the engines operation parts of loads and nominal loads.

Abstract:
There is no industrial sector in which welding is not used as a manufacturing process. Welding assembly is a highly polluting technology process, especially of the atmosphere and soil. The formation of gases in the welding process is the result of burning the electrodes, flows, forming the molten metal bath and making the weld seam. Welding operators are exposed to smoke and toxic gases resulting from the welding process, which may be dangerous to health. Many acute intoxications due to excessive exposure or short-term exposure to smoke and gas resulting from the welding process have been studied over time. However, in addition to general effects such as respiratory irritation, long-term effects have been directly attributed the influence of smoke and toxic gases, for example, the chronic effects due to the presence of chromium, nickel and aluminum. There are some welding sections where the level of noxes exceeds the limits allowed by the law, and in these cases it is fairly possible to speak of so-called chemical risk. The paper aims is to measure the emissions of noxious substances in case of welding of welded specimens and if the limits allowed by the welding laws are exceeded, to present a chemical risk assessment algorithm, going through three stages: inventory of materials and products used at a workstation, hierarchy of potential risks noted IRP and ultimately, the risk assessment.

Abstract:
Impregnated activated carbons (IACs) used in air filtration gradually lose their efficacy for the chemisorption of noxious gases when exposed to humidity due to impregnated metal deactivation. In order to stabilize IACs against aging, and to prolong the filters’ shelf life, inorganic phosphate compounds (phosphoric acid and its three salts, NaHPO4, Na2HPO4, and Na3PO4) were used as anti-aging additives for two different chromium-free IACs impregnated with copper, zinc, molybdenum, and triethylenediamine (TEDA). Phosphoric acid, monosodium, and disodium phosphate were found to be very efficient in inhibiting the aging of IACs over long periods against cyanogen chloride (the test agent) chemisorption, with the latter being the most efficient. However, the efficiency of phosphate as an anti-aging additive was not well correlated with its ability to inhibit the migration of metal impregnants, especially copper, from the interior to the external surface of carbon granules. Unlike organic additives, the inorganic phosphate additives did not decrease the surface area of the IAC or its physical adsorption capacity for toluene. Using a phosphate additive in IAC used in collective protection and personal filters can improve the safety of the user and the environment and dramatically reduce the need to replace these filters after exposure to humid environments. This has safety, economic, logistical, and environmental advantages.

Abstract:
A modified charcoal kiln was developed for both thermal therapy and charcoal production. The design of a modified kiln for thermal therapy focused on safety and cleanliness, plus the production of good quality charcoal. Two entrances in the kiln were designed for convenient charcoal production and thermal therapy. A barrier wall designed for noxious gases was installed between the adjoining charcoal kilns for safe thermal therapy. Additionally, a fine dust collector was installed to remove the fine dust generated during charcoal production. To verify the safety of the kiln, fine dust and harmful gases, such as carbon monoxide (CO), carbon dioxide (CO2), nitrogen dioxide (NO2), and radon (Rn), were measured after the charring process. The quality of the charcoal produced in the thermal therapy kiln was also examined. To evaluate charcoal quality, some physical properties and results from a proximate analysis were evaluated using Korean standards. The measurements of harmful substances and fine dust in the modified charcoal kiln met the criterion of the Ministry of Environment Clean Air Conservation Act in Korea. In addition, there were no noticeable differences in the monthly charcoal characteristics prepared from the thermal therapy kiln, and the charcoal characteristics also met the reference values of the Korea Forest Service.

Abstract:
Broiler production is highly dependent on the use of artificial light. The light source may affect the effectiveness of housing conditions due to increasing ambient temperature and concentration of noxious gases. This research aimed to evaluate the effects of different bulb types on the thermal, aerial, and acoustic environment of broiler aviaries. The experiment was carried out at a commercial broiler farm in Dourados, Mato Grosso do Sul State, Brazil. Three aviaries were used, and two flocks of male broilers from Cobb® genetic strain were reared from the first day to slaughter. Each aviary was equipped with a different light source, comprising the adopted treatments (A1 - incandescent light bulb, control; A2 - sodium vapor light bulb; A3 - fluorescent light bulb). The aviaries were divided into nine quadrants, and the environmental data (ambient dry bulb temperature and relative humidity), litter surface temperature, CO2 and NH3 concentrations, and bird sound pressure behavior were recorded in each quadrant. The aviary with incandescent light presented higher air and litter temperatures, and concentration of gases than the other tested alternatives. It also presented higher level of sound pressure in the second week of the growing period; however, from this period up to slaughter, there was no effect of the light source on the results of broiler sound pressure level.
