Present study aims to determine the lead (Pb) concentrations in the feather samples of cattle egret (Bulbulcus ibis) found in different contaminated wetland habitats present in the state Odisha, India. This study also focused on the heavy metal concentrations of top layer soil and on the level of metal accumulation in prey samples (i.e. small fishes) preferred by cattle egrets for explaining the level of amplification of Pb in different polluted wetland habitats. Moreover, reasons behind the variations of Pb concentrations within the sampled wetland habitats are explained. Feathers, Prey samples and sediments from their foraging habitats were collected from eight different heronries. Determination of Pb concentrations in samples has undergone acid digestion followed by elemental analysis (i.e. Pb) in Atomic Absorption Spectrophotometer (AAS). The results indicated that Pb concentration was varied significantly in soil (15.13-56.26µg/g), Prey (0.21-55.76µg/g) and feathers (5.6-49.86µg/g) in different sites. The highest concentration was found at Hirakud in soil and prey. However, feather samples showed the highest concentrations of lead in Talcher may be due to the mining activities in and around the sampling location. Present study found the positive correlation (p<0.05) between soil, prey and feather samples of cattle egret among the eight sampling locations may be due to many of the mining, industrial and anthropogenic sources. The processes like geophagy and biomagnification may contribute to the positive correlation among the sampling habitats. Concluding this work, it might be confirmed that avian feathers can be used as non-destructive biomonitoring tool for assessment of the heavy metal contamination level in various segments of different ecosystems. Hence, based on the results of the study, the environmental management plan could be suggested and implemented for better conservation of the avian fauna.

Heavy metal contamination to Poyang Lake is increasingly severe. Bellamya aeruginosas, the dominant species of bellamya in Poyang Lake, was chosen in this project to carry out a proteomics study, because they obtain nutrients from sediments directly and have a strong heavy metal enrichment capability. To get a better knowledge of the contamination level of Poyang Lake and a better understanding of toxicity and bioavailability of heavy metals contamination, the main heavy metals of surface sediments were tested and a proteomics study was carried out on bellamya aeruginosa, the dominant species of bellamya in Poyang Lake. Results of heavy metal tests show, to Poyang Lake, the most contaminated heavy metal is Cu, the widest contaminated heavy metal is Pb, the most contaminated area is the south lake area, and the least contaminated area is the entrance of Xioushui River. Proteomics analysis shows the main significantly different proteins are keratins or similar substances. These proteins are higher expressed in the samples obtained from the most contaminated area, so they could be the responding biomarkers for monitoring heavy metal contamination of surface sediment in Poyang Lake.

AbstractThe incidence of heavy metal contamination in Zamfara State, northern Nigeria, due to artisanal mining in some villages has resulted in the pollution of a vast area of land and water. This study evaluated the extent of environmental risks caused by heavy metals. It involved five (5) villages (Bagega, Dareta, Sunke, Tunga, and Abare) where mining activities were taking place and Anka town with no record of mining activities served as control. In each of the five villages, three sites (3) were identified as a mining site, processing site, and village making a total of sixteen (16) sites. Bulked soil samples were collected in triplicate and analyzed for iron, lead, cadmium, chromium, zinc, and nickel using flame atomic absorption spectrophotometry. Measured concentrations of the heavy metals in soils were then used to calculate the pollution and ecological risk pose by heavy metals. Their concentrations were in the order Fe > Pb > Cr > Zn > Cd > Ni, with Pb and Cd having a concentration higher than permissible levels for soils and accounted for 98.64% of the total potential ecological risk. Also, all the different pollution indices examined showed that all the sites were polluted with Cd, and all the processing sites were polluted with Pb. This reveals that processing sites pose more risk to heavy metal contamination. Correlation analysis showed a highly significant (p < 0.001) positive correlation between Pb and Zn, Cr and Ni, and a significant (p < 0.01) positive correlation between Fe and Pb, Zn and Cr. The principal component analysis suggested that Pb, Zn, Cr, and Ni likely originated from the same source, i.e., mining activities, and Fe and Cd originated from the abundant parent material in the study area.

The potency and utilization of Lampung Bay has been recognized for their socio-economical and ecological values. However, heavy use of this Bay may alter the abundance of hazardous chemical like heavy metals. The aims of this study were to determine the concentration of Cd, Cu, Pb and Zn in the sediment and to assess Lampung Bay water condition. The observation of heavy metal content in sediment of Lampung Bay was conducted at 13 stations in March 2008. Analysis of heavy metals in sediment was conducted using three kinds of acid: HNO3, HCl and H2O2 while measurement was carried out by Atomic Absorption Spectrophotometer. The result indicated a variation of heavy metal concentration in sediment and that concentrations of Cd, Cu, Pb and Zn in sediment were 0.08 mg/kg dry weight, 22.99 mg/kg dry weight, 24.75 mg/kg dry weight and 118.48 mg/kg dry weight, respectively. Factors influenced heavy metal concentration in sediment in this study including the distance between sampling location and anthropogenic activities and the sediment fraction  SQG-Q index indicated that 7 stations have SQG-Q ≤ 0.1 whereas other 6 stations have 0.1≤ SQG-Q <1, meaning that more than half sampling stations are in uncontaminated state.

Examination of heavy metals (Cr, Cu, Zn, Pb, Hg, Cd and Ni) in overlying water and sediments was conducted in Lake Nkozoa, in a peripheral area of Yaoundé characterized by a high population density and rapid economic development in Cameroon. Sediment samples were collected at the entrance and near the center of the lake, using a raft and polyvinyl chloride (PVC) pipes. They were subjected to water quality parameters, heavy metals comparisons and calculations of pollution indices and ecological risks followed by statistical analysis in order to identify and estimate the sources of metal contamination in overlying water and sediments of the Nkozoa Lake. The physico-chemical parameters of water show that the pH (5 < pH < 6), total dissolved solids (TDS~130 g/L) and conductivity (EC~194.8 µs/cm) are below the recommendations of the WHO. The average heavy metal concentrations in sediments, except Cd, are lower than the upper continental crust (UCC) and several environmental contamination monitoring parameters, such as threshold effect level (TEL), probable effect level (PEL), and severe effect level (SEL). The sediment samples show a low heavy metal contamination degree (class 0) and low potential ecological risk (PER) level, except for Cd and Hg which have high contamination degree (class 1 to 6) and moderate PER. Matrix correlation shows that some parameters like pH, EC, Cr and TDS, Cu, Hg in water have perfect positive correlations (r = 1.00) suggesting common sources of contamination. Cluster analyses coupled with matrix data for sediments revealed that Cd is the most contaminant elements derived from anthropogenic sources.

Acceptable Limit

Paddy plants tend to accumulate heavy metals from both natural and anthropogenic sources, and this poses adverse risks to human health. The objective of this study was to investigate heavy metal contamination in paddy plants in Kelantan, Malaysia, and its health risk assessment. The bioaccumulation of heavy metals was studied by means of enrichment (EF) and translocation factors (TF). The health risk assessment was performed based on USEPA guidelines. The EF for heavy metals in the studied areas was in the descending order of Cu > As > Cr > Cd > Pb. Meanwhile, Cr and Pb exhibited higher TF values from stem to grain compared with the others. The combined hazard index (HI) resulting from five heavy metals exceeded the acceptable limit (HI >1). The lifetime cancer risk, in both adult and children, was beyond the acceptable limit (10−4) and mainly resulted from exposure. The total cancer risk (CRt) due to simultaneous exposures to multiple carcinogenic elements also exceeded 10−4. In conclusion, intake of heavy metal through rice ingestion is likely to cause both non-carcinogenic and carcinogenic health risks. Further research is required to investigate the extent of heavy metal contamination in agricultural soils and, moreover, to establish human exposure as a result of rice consumption.

The present study was conducted to figure out the heavy metals (Cd, Co, Cu, Fe, Hg, Mn, Mo, Ni, Pb and Zn) concentrations in water, sediments and fish species from the Rupsha River, Khulna, Bangladesh to spot the heavy metal contamination level. Heavy metals are dangerous because they're non-biodegradable and having an extended half-life period. The heavy metal contamination could also be an excellent concern, especially for aquatic life. The metal concentration within the water sample from the Rupsha River was significantly above the rule values of WHO and USEPA respectively. Moreover, the concentration of metal within the sediments was also greater than the respective probable effect concentrations of the sediment quality guidelines. Furthermore, consistent with the fish standards, these studied fish species weren't found to be contaminated by heavy metals. It’s concluded that each of the heavy metals from the whole sample didn't exceed the standard maximum level. This study demonstrated that water of Rupsha River isn't safe for aquatic organisms also like humans in terms of Pb, Cd and Cr contents as accumulated through consumption.
