AbstractThis investigation focused on plankton inhabiting fishponds, which previously received mine waters from the lead-zinc mine ‘Matylda’, located in southern Poland (Upper Silesia). The purpose of the investigation was to study the effects of chronic and persistent contamination of fishpond bottom sediments with heavy metals originated from the lead and zinc mine. The phyto-and zooplankton in the four fishponds were dominated by diatoms, green algae and rotifers. Plankton composition of the reference non-contaminated pond was different, since Chrysophytes dominated, and Copepoda were the most numerous among zooplankton. In the contaminated fishponds, we observed teratological forms, both for phyto-and zooplankton species, but only as individuals. Our results showed that planktonic communities had adapted to chronic and persistent heavy metal contamination.

According to the primary study on the As contamination in soil and crops including potato and pea in tin tailings in Gejiu area, Yunnan Province, it has been found that concentrations of As in rhizosphere far exceed Chinese National Grade Ⅲ standard of soil environmental quality of China (GB 15618-1995). It also has been found that the Ferns were living in the tin tailings suffered from the contamination of heavy metals. Compared with the limit of national criteria for food sanitation in China, the concentrations of As in edible parts of ferns are 90 times. Therefore, the remediation of soil based on geochemical distribution characteristics of heavy metal in the tailings is demanded. And avoiding crops-planting in the tailings to reduce the diffusion of heavy metal contamination in food chain of mining area is necessary.

Heavy metal is a member of loosely defined subset of elements that exhibit metallic properties. It mainly includes the transition metals, some metalloids, lanthanides, and actinides. Heavy metals are ubiquitous in the environment, as a result of both natural and anthropogenic activities. They are stable and cannot be destroyed, and therefore tend to accumulate in the environment. In recent years, there has been a substantial concern over the extent of contamination of the environment with toxic elements. Soil pollution caused by rapid industrial activities has become a worrisome phenomenon due to its impact on soil and environment. Heavy metal pollution in soil arising from industrial discharges significantly poses a great threat to the environment. Heavy metals come to the soil by several ways and the soil becomes toxic which cause serious problem to the environment. In toxic soil, microorganisms cannot persist and there create an imbalance situation in the soil. The main objective of this study was to assess the problem of heavy metal contamination in industrial area soil in Bangladesh with environmental risk assessment.
