Abstract:
After cultivating 4 days in Steinberg medium with different concentrations of Cd2+, the toxic effect of cadmiun on Azolla imbricata (Roxb.) Nakai was investigated for the purpose to find out if this plant is suitable to using on restoration of waterbody with cadmium pollution. The variations of chlorophyll content, soluble-protein content, peroxidase (POD) activity, catalase(CAT) activity, and malondialdehyde (MDA) content of Azolla imbricata (Roxb.) Nakai were measured in this study. The results show that the chlorophyll content of Azolla imbricata(Roxb.)Nakai has no significant changes in media with Cd2+concentrations compare with control. The MDA content ascended significantly from the Cd2+concentration was 5 mg•L-1, because of the intensified oxidative damage. When Cd2+concentration is 0.1~20 mg•L-1, the souble protein content, POD activity and CAT activity increased to resist the oxidative damage. Azolla imbricata (Roxb.) Nakai is tolerance of cadmium pollution, it can be used to water bodies restoration with low level cadmium pollution.

Abstract:
SynopsisThis paper briefly reviews the legal framework of pollution control in Orkney, and discusses the occurrence of the main categories of contaminants there.There is no indication of elevated concentrations of organohalogen compounds in Orkney shellfish. The main potential source of hydrocarbon contamination is thoroughly monitored, and no major adverse effect has been noted.High concentrations (up to 62 μg/g wet wt) of cadmium occur in edible crab hepatopancreas from Orkney, Shetland and surrounding areas. A consideration of cadmium concentrations in a range of species suggests a regional geochemical anomaly for cadmium, affecting biota perhaps through solid phases.

Abstract:
After 4 days exposed to cadmium concentration environment, the soluble protein content, SOD activity, CAT activity, POD activity and MDA content of Hydrocharis Dubia root were investigated in this paper to study if this plant can be used to waterbody restoration with cadmium pollution. The result showed that when the cadmium concentration was lower than 5 mg.L-1, the plant didn’t encounter seriously oxidant damaged. The plant root cell increased SOD activity, CAT activity and POD activity to clean up these accumulated ROS. Hydrocharis Dubia can be used to waterbody restoration with lower than 5 mg.L-1 cadmium pollution. The plant unsuitable to be used to waterbody restoration with higher than 5 mg.L-1 cadmium pollution, the plant encountered seriously oxidant stress in this level cadmium pollution.

Abstract:
The variation of antioxidant activity of aloe vera under the stress of cadmium with different concentration was studied. The scavenging capacity of potted aloe vera to •OH and O2- • was determined and the effects of cadmium pollution on the antioxidant activity of aloe vera were evaluated using flow injection chemiluminescence methods.The results showed that, at low cadmium pollution level, the antioxidant activity of aloe vera increased with the increase of cadmium content in aloe vera body; while at high cadmium pollution level, the antioxidant activity of aloe vera decreased with the increase of cadmium content. This indicated that low cadmium could stimulate the self-protection system of aloe vera, resulting in a increase in the antioxidant activity. high cadmium would damage aloe self-defendend system, leading to the decrease in antioxidant activity.

Jackson, Paul P. "Removal of cadmium from polluted water by immobilized algae." Thesis, Durham University, 1990. http://etheses.dur.ac.uk/6184/.

Abstract:
A feasibility study was planned to determine the efficiency of immobilized algal cells growing in a packed bed for removing Cd from commercial effluents. To select appropriate material for an immobilized cell system, twenty-five strains of algae isolated from heavy-metal contaminated environments of known water chemistry were tested for their ability to accumulate Cd. Before accumulation experiments were initiated, ion exchange resin was employed to demonstrate that EDTA in the medium did not complex Cd to a significant degree. Svnechococcus D562 cells subcultured in Cd accumulated the most metal; little was bound to the cell wall. A continuous culture of steady- state Svnechococcus D562 cells tolerated a lower maximum concentration of metal (3.4 mg 1(^-1) Cd) than batch- cultured cells (5 mg 1(^-1) Cd), indicating that metabolic status influences the toxicity of Cd. When flasks of calcium-alginate beads were challenged with Cd, up to 60 % of the added metal was bound within 16 h; however, further incubation did not reduce the pollutant concentration. Two axenic strains which accumulated the metal to a high concentration were then immobilized and tested for their capacity to remove Cd from the circulating medium. A packed-bed reactor containing Mougeotia D536 cells proved more effective at metal removal than Svnechococcus D562, but both species grew to a lower cell density at the effluent end of the column. The medium was then aerated to overcome such growth-limiting conditions, but this treatment inhibited Cd accumulation. Column-immobilized cells reduced Cd levels more effectively than inoculated, alginate beads in stationary flasks or free cells. Energy dispersive X-ray microanalysis located Cd only in particular Svnechococcus D562 polyphosphate bodies (those with a high Ca to K ratio); peaks for Zn, Pb, Fe, Mn and Ba were also detected in algae isolated from the field. Scanning proton microanalysis provided information on the distribution of macro- and micro-elements throughout the two strains of cyanobacteria and two strains of algae selected from the Durham Culture Collection and demonstrated the presence of Cd in Klebsormidium rivulare D537.Detergent-sensitive spheroplasts of Svnechococcus D562 were produced by lysozyme and protease digestion, but were not viable for growth. To observe the extracellular mucilage of this strain by EM, lysozyme digestion proved imperative for effective ruthenium red staining to convert the material into an electron opaque material. From cultures of Svnechococcus D562 grown with or without Cd a 14 kD plasmid was isolated, which contained two Eco RI, two Bam HI and five Hind III restriction sites. A radiolabelled oligonucleotide probe based on part of the nucleotide sequence of a metallothionein from Svnechococcus FCC 6301 did not bind to a genomic and plasmid blot of Svnechococcus D562 DNA. The putative Cd-binding peptides ((yEC)(_n)G's) that were discovered only bound significant quantities of the metal when cells were exposed to 6.17 mg 1(^-1) Cd for 2 days at the end of their log-growth phase. Indigenous peptides failed to bind substantial amounts of the metal and the presence of Cd throughout growth did not influence the quantity of chelated Cd, except for Mougeotia D536. The pH of half displacement for (yEQjp's from this strain is comparable with that of other species. Reversed-phase HPLC of the peptides from Mougeotia D536 generated a thiol profile similar to that recorded for the Cd-binding peptides of Datura innoxia. The Cd-induced ultrastructural distortions that were recorded include potential Ca / P / Cd precipitates in Mougeotia D536, the loss of polyglucoside granules from Calothrix D184 together with a relaxation of its thylakoid packing and a lack of plastoglobuli in Cd-exposed Klebsormidium D537. The space between an immobilized cell and the matrix either represents shrinkage of the matrix during dehydration or mucilage which does not bind electron dense stains. Release of alkaline phosphatase into the medium by Svnechococcus D562, provided suitable material to study the inhibitory effects of Cd upon P hydrolysis. Ultrafiltration membranes proved effective as initial step towards enzyme purification and for the determination of activity under sub-optimal pH conditions. At pH 7.0, the activity of an enzyme concentrate was inhibited when 1 and 10 mg 1(^-1) Cd were added to the assay medium, but the presence of this metal in the growth medium did not reduce activity. One-dimensional SDS PAGE revealed only one protein difference between strains grown with or without Cd; a reduction in the staining intensity of a 17 kD band of Calothrix D184.

Abstract:
Metallothioneins are ubiquitous sulphur-rich heavy metal binding proteins whose biosynthesis is induced in response to a variety of agents, including heavy metals. A number of isoforms of metallothionein are known to be induced by heavy metals in the common mussel Mytilus edulis, and recently interest has centred on the nature of these proteins and their possible utility as pollution indicator agents. Cadmium-induced metallotheioneins were isolated from mussels by procedures which included gel permeation and anion-exchange chromatography. They were shown to comprise two molecular mass classes of 10 and 20KDa. The 10kDa class was resolved by anion-exchange into four components designated 10-I, 10-II, 1--III and 10-IV. The 20kDa class was similarly resolved into three components designated 20-I, 20-II and 20-III. The amino acid sequences of each of the components in both of the classes were determined. This involved digestion with a variety of proteinases and separation of the resulting peptides. The abundance of crysteines in these mussel metallotheioneins necessitated their derivatisation with methyl-p-nitrobenzenesulphonate to generate the S-methyl derivative of cysteine which has been found to be suitable for peptide mapping by HPLC and sequence analysis by automated methods. The components of the 20kDa class were shown to possess linked peptides consisting of 71 amino acids, which were distinct from the 72 amino acid peptides of the 10kDa class. It is suggested that the two monomers in the 20kDa proteins are linked via S-Cd-S bonding, i.e. a bridging cadmium ion. The various components within both classes exhibited homology, particularly with regard to the location of the cysteine residues, to metallothioneins from other species, including mammals. On the basis of this homology these proteins were classified as class I metallothioneins.

Abstract:
Cadmium in the ocean has a nutrient-like cycling pattern: with biological uptake at the surface, subsequent sinking in particulate form and then regeneration as dissolved species in deeper waters. Many measurements have been made over time of the ratio of the concentrations of dissolved Cd to those of PO₄ (Cd/PO₄) in the world ocean and this has become one of the best relationships documented between a trace metal and a nutrient. Combined with the measurements of the Cd/Ca ratio in foraminifera, the Cd/PO₄ ratio has been used to reconstruct the oceanographic circulation patterns that existed during past glacial periods and hence provides information on past climate changes. In the present study Cd/PO₄ ratios of the Southern Indian Ocean in surface and deep waters were investigated. The slopes of the relationships between Cd and PO₄ concentrations in waters of this region are high compared to the global correlations, and lie between those reported for other parts of the Southern Ocean and the Pacific Ocean. In surface waters of the Southern Indian Ocean, Cd/PO₄ ratios decrease from regions exhibiting high nutrient-low chlorophyll (HNLC) characteristic in the south to oligotrophic waters further north. It is also found that particulate Cd plays an important role in regulating the high Cd/PO₄ ratios reported in waters south of the Polar Front. Very low Cd/PO₄ ratios were measured in waters associated with the Subtropical Front southeast of New Zealand compared to other Southern Ocean and global oceanic waters. Seasonal variations in the Cd/PO₄ ratios measured for these waters strongly suggest they are associated with a significant biological uptake of dissolved Cd particularly during the phytoplankton growth season in summer. Dissolved Fe concentrations in the Southern Indian Ocean and seasonal variations of Fe in waters off the Otago Coast (southeast of New Zealand) suggest that Fe may stimulate phytoplankton growth and this might result in lower Cd/PO₄ ratios in surface waters through enhanced Cd uptake relative to PO₄ by the phytoplankton. However there is no distinct relationship between dissolved Fe concentrations and the dissolved Cd/PO₄ ratios measured in these surface waters. This finding is in disagreement with the recent 2006 hypothesis put forward by J.T. Cullen, which proposed that waters exhibiting low dissolved Cd/PO₄ ratios were associated with the HNLC regions. From a consideration of the potential Zn concentrations calculated from Si concentration measurements reported for these waters, it would appear that Zn may play a more important role than Fe in regulating Cd/PO₄ ratios in these waters. Measurements of dissolved and total Cd concentrations relative to those of PO₄ were also undertaken in the Otago Harbour and immediate surrounding coastal waters. These exhibited higher Cd concentrations and higher Cd/PO₄ ratios than open ocean waters further off the Otago Coast. The particulate Cd concentrations showed a negative correlation with Cd concentrations measured in cockle species (Austrovenus stuchburyi) collected in the harbour, suggesting that particulate Cd is not the source of Cd measured in the tissue of this species. The concentrations of Cd and other trace metals were also measured in samples of green mussel (Perna canaliculus), ribbed mussel (Aulacomya atra maoriana) and oyster (Saccostrea cucullata) collected from Otago Harbour and possible correlations explored between these concentrations and other parameters such as the shellfish condition indices and environmental gradients in the harbour. In summary, measurements of dissolved and particulate Cd concentrations in the water column can provide unique information on a number of processes occurring in the global marine environment.

Abstract:
L'objectif de cette etude est de determiner, et de quantifier, les mecanismes intervenant des melanges d'argile et de ciments, appeles coulis, lors de la retention de plomb, de cadmium et de zinc. La diversite et la complexite des phenomenes mis en jeu a conduit a l'elaboration d'un modele global couplant transport et geochimie. Le module de transport est base sur le concept des differences finies en une dimension. Celui de geochimie sur la methode des composantes de base a partir de constantes thermodynamiques. Le couplage s'effectue sur deux pas, les inconnues principales du calcul etant les concentrations totales par defaut. La prise en compte des solides, difficulte majeure pour la methode des composantes de base, est resolue par changement de base automatique. La partie experimentale est axee sur deux types d'essais: - essais de retention sur des granules de coulis durcis (melange argile-ciment-gravier) des polluants seuls ou ensembles (tests d'equilibre) ; - essais de percolation de solutions complexes sur des eprouvettes contenant differents melanges argile-ciment durcis. L'interpretation des tests d'equilibre est effectuee a l'aide du module de calcul d'equilibre geochimique seul. Il apparait que les mecanismes de retention des metaux lourds etudies sont essentiellement domines par la precipitation (hydroxydes, carbonates, chlorures ou sulfates) et par l'adsorption. Celle-ci est attribuee aux silicates de chaux hydrates (csh), constituants majeurs des coulis durcis. La fixation, particulierement intense, s'effectue par le biais d'un echange entre une fraction du calcium, sans doute adsorbee sur les csh, et les metaux. Ces reactions chimiques, tres dependantes du ph, ont ete etablies et leur constante intrinseque d'adsorption estimees d'apres la theorie de la double couche generalisee. Les essais de percolation se sont poursuivis pendant une annee a l'issue de laquelle aucune concentration notable de polluant n'a ete detectee en sortie de colonne. La comparaison du positionnement des differents fronts de polluant dans la colonne entre le calcul et le resultat experimental est satisfaisante et permet de valider le modele mis en place lors des tests d'equilibre

Des sols contaminés uniquement en Cd, depuis une longue période, ont d'abord été utilisés pour évaluer les effets d'exsudats racinaires de faible masse moléculaire, libérés dans un système modèle par un filtre placé à la surface du sol, sur les biomasses microbiennes carbonées et azotées, la respiration microbienne, le pool inorganique d'N et la biodisponibilité de Cd dans la rhizosphère (BIOMET®). L'utilisation d'une espèce végétale, Holcus lanatus L. , pour la phytoremédiation aidée de sols contaminés en Cd a été étudiée de façon préliminaire en solution hydroponique sur 4 semaines. Les plantes, dont le système racinaire a été lavé, ont été placées dans une solution nutritive simulant la concentration en Cd extrait et le pH des parcelles d'origine. La concentration et la quantité de Cd ont été quantifiées dans les parties aériennes, les feuilles et les racines. On a mesuré les activités enzymatiques Guaiacol peroxidase dans les feuilles, ainsi que leur densité en chlorophylle et caroténoïdes totaux. L'assainissement des sols contaminés en Cd a été étudié en utilisant une technique de stabilisation in situ basée sur l'apport au sol de l'un des 3 composés inorganiques suivants: beringite + grenailles d'acier, sépiolite, et bentonite. La concentration en Cd a été mesurée dans la solution du sol (Rhizon) au cours des premiers jours suivants l'amendement du sol et après 6 mois. L'efficacité de la remédiation des sols contaminés en Cd par stabilisation in situ a été évaluée en vase de végétation placés sous serre, avec 3 végétaux de sensibilité différente à l'exposition au Cd (sensible: Phaseolus vulgaris, moyennement tolérante: Holcus lanatus, tolérante: Lactuca sativa).

Abstract:
On a global basis, trace-metal pollution is one of the most pervasive environmental problems. It is particularly difficult to prevent or clean up because the metals are toxic in their elemental form and cannot be decomposed. Bioremediation has been shown to be a powerful system for heavy metal pollution clean up and prevention. In this work, we characterized the cadmium (Cd)-resistant bacteria isolated from rice field soil downstream from zinc (Zn) mineralized area which the owners were contaminated at high level of cadmium content in their blood (>10 μgCd/g creatinine). We found that all 24 isolated bacteria tolerated toxic Cd concentrations (2,500 μM). In order to determine whether the Cd toxicity affected the growth of isolated bacteria, we grew the isolated bacterial cells in the absence and presence of toxic concentrations of CdCl2 (500 μM). In the absence of Cd, all isolated bacterial cells grew slightly better than in the presence of toxic concentrations of Cd. In addition, the Cd binding capacity of all isolated bacteria were very high, ranging from 6.38 to 9.38 log[Cd(atom)]/cell when grown in the presence of 500 μM CdCl2. Furthermore, the stability of Cd-bacteria complex of all isolated bacteria was affected by 1mM EDTA. When grown in the presence of 500 μM CdCl2, Cd-resistant isolates S2500-6, -8, -9, -15, -17, -18, -19, and -22 increasingly produced proteins containing cysteine (SH-group) (from 1.3 to 2.2 times) as well as 11 isolates of Cd-resistant bacteria, including S2500-1, -2, -3, -5, -6, -8, -9, -11, -16, -20, and -21, increasingly produced inorganic sulfide (1.5 to 4.7 times). Furthermore, the Sulfur K-edge X-ray absorption near-edge structure (XANES) spectroscopy studies indicated that Cd-resistant isolated S2500-3 precipitated amounts of cadmium sulfide (CdS), when grown in the presence of 500 μM CdCl2. The results suggested that these Cd-resistant bacteria have potential ability to precipitate a toxic soluble CdCl2 as nontoxic insoluble CdS. Interestingly, Cd-resistant bacteria isolated S2500-3, -8, -9,and -20 increased cadmium tolerance of Thai jasmine rice (Kao Hom Mali 105) when grown in the presence of 200 μM CdCl2. These 4 isolates also decreased cadmium concentration accumulation in Kao Hom Mali 105 plant at 61, 9, 6, and 17%, respectively when grown in the presence of 200 μM CdCl2. They were identified by 16S rDNA sequence analysis and classified as Cupriavidus taiwanensis (isolate S2500-3) and Pseudomonas aeruginosa (isolates S2500-8, -9, and -20).

Abstract:
At our previous laboratory experiments, it was found that different spring barley varieties have some different reactions to the cadmium stress at the morphologic, cytogenetic and biochemical levels of plants organization. Thus, the goal of the current work was to assess the reliability of the previous results at full vegetation cycle of plant. The experiment was carried out on the loamy soil with four contrasting at its reactions to the cadmium barley varieties. Cadmium tolerant varieties demonstrated significantly higher values of productivity (e.g. straw, in this case, weighted four times more) and had a less amounts of Cd2+ accumulated at tissues (1.2–2.5 times) in contrast to sensitive ones, which, in fact, gave no harvest at Cd2+pollution at a rate of 50 mg/kg. The identified polymorphism of barley varieties in terms of resistance is maintained throughout the plant’s life cycle.

Abstract:
Air pollution has become a serious issue and has continually increased since the half-decade ago due to globalization. Activities such as urbanization, industrialization, power plants, agricultural open burning and natural disaster such as wildfires are the key factors in air pollution. The air pollutants produced include particulate matter (PM10 and PM2.5), ozone (O3), carbon monoxide (CO), sulfur dioxide(SO2), nitrogen dioxides (NO2) and heavy metals such as lead (Pb) and cadmium (Cd). According to the most recent revision of the Global Burden of Diseases (GBD), PM10 and PM2.5 were listed as the fourth most common killer out of 85 risk factors. Hence, it is important to assess air pollution, especially the particulate matter concentration in the air. In this study, we emphasize the development of PM2.5 prediction models using machine learning for air pollution evaluation in Selangor, Malaysia. This is because Selangor contributed most pollutants due to its highest population distribution in the country. The machine learning models involved are Random Forest, Naïve Bayes, KNN, SVM, and Gradient Boosting. Gradient boosting and Random Forest contributed comparable prediction results. However, gradient boosting was chosen as the best model for the prediction in this study due to the accuracy and precision in predicting the Classes of PM2.5 without misclassification. The accuracy, precision, and recall of the model are 99.9% and 99.94% for F1 score respectively.

Abstract:
Urban pollution has different forms; one of them is air pollution by natural sources such as dust storms or by anthropogenic sources such as traffic, whereas both are considered among the most risky environmental problems especially when it reaches soil surface and is transported to plants and enters food chain. The current study aims to evaluate the heavy metals in dust, deposited on the leaves of the Sidr trees by roadsides as a first step in assessing the use of this plant as a bio-monitor of environmental pollution. The Sidr tree was chosen to evaluate the impact of pollution because it is very common in the region and among evergreen trees in the streets, gardens and residential areas of Doha. The study was carried out close to Qatar University campus in Doha city (traffic intersections and near construction activities) as well as from a farm (located far away from traffic) as a control sample. The concentrations of ten traffic-related metals namely iron (Fe), cadmium (Cd), lead (Pb), copper (Cu), nickel (Ni), zinc (Zn), manganese (Mn), aluminum (Al), barium (Ba), and mercury (Hg) were determined in the deposited dust on leaves using ICP-OES. In our preliminary findings, we found that the distribution of trace metals in leaf dust samples from our study is similar to those reported in an earlier study done in southwestern Iran.

Abstract:
Stormwater management is an ongoing challenge in the United States and the world at-large. As state and municipal agencies grapple with conflicting interests like encouraging land development, complying with permits to control stormwater discharges, “urban stream syndrome” effects, and charges to steward natural resources for the long-term, some agencies may turn to constructed wetlands (CWs) as aesthetically pleasing and functional natural analogs for attenuating pollution delivered by stormwater runoff to rivers and streams. Constructed wetlands retain pollutants via common physical, physicochemical, and biological principles such as settling, adsorption, or plant and algae uptake. The efficacy of constructed wetlands for pollutant attenuation varies depending on many factors such as flow rate, pollutant loading, maintenance practices, and design features. In 2018, the culmination of efforts by Clackamas Water Environment Services and others led to the opening of the Carli Creek Water Quality Project, a 15-acre constructed wetland adjacent to Carli Creek, a small, 3500-ft tributary of the Clackamas River in Clackamas County, OR. The combined creek and constructed wetland drain an industrialized, 438-acre, impervious catchment. The wetland consists of a linear series of a detention pond and three bioretention treatment cells, contributing a combined 1.8 acres of treatment area (a 1:243 ratio with the catchment) and 3.3 acre-feet of total runoff storage. In this study, raw pollutant concentrations in runoff were evaluated against International Stormwater BMP database benchmarks and Oregon Water Quality Criteria. Concentration and mass-based reductions were calculated for 10 specific pollutants and compared to daily precipitation totals from a nearby precipitation station. Mass-based reductions were generally higher for all pollutants, largely due to runoff volume reduction on the treatment terrace. Concentration-based reductions were highly variable, and suggested export of certain pollutants (e.g., ammonia), even when reporting on a mass-basis. Mass load reductions on the terrace for total dissolved solids, nitrate+nitrite, dissolved lead, and dissolved copper were 43.3 ± 10%, 41.9 ± 10%, 36.6 ± 13%, and 43.2 ± 16%, respectively. E. coli saw log-reductions ranging from -1.3 — 3.0 on the terrace, and -1.0 — 1.8 in the creek. Oregon Water Quality Criteria were consistently met at the two in-stream sites on Carli Creek for E. coli with one exception, and for dissolved cadmium, lead, zinc, and copper (with one exception for copper). However, dissolved total solids at the downstream Carli Creek site was above the Willamette River guidance value 100 mg/L roughly 71% of the time. The precipitation record during the study was useful for explaining certain pollutant reductions, as several mechanisms are driven by physical processes, however it was not definitive. The historic rain/snow/ice event in mid-February 2021 appeared to impact mass-based reductions for all metals. Qualitatively, precipitation seemed to have the largest effect on nutrient dynamics, specifically ammonia-nitrogen. Determining exact mechanisms of pollutant removals was outside the scope of this study. An improved flow record, more targeted storm sampling, or more comprehensive nutrient profiles could aid in answering important questions on dominant mechanisms of this new constructed wetland. This study is useful in establishing a framework and baseline for understanding this one-of-a-kind regional stormwater treatment project and pursuing further questions in the future.
