Mercury and cadmium toxicity

Persistent heavy metal pollution poses a major threat to all life forms in the environment due to its toxic effects. These metals are very reactive at low concentrations and can accumulate in the food web, causing severe public health concerns. The use of microbial biosorbents is eco-friendly and cost effective; hence, it is an efficient alternative for the remediation of heavy metal contaminated environments.

Heavy metals like cadmium, nickel, lead, chromium, mercury etc are important environmental pollutants in areas with anthropogenic pressure. Their presence in the atmosphere, soil and water, even in traces can cause serious problems to all organisms. Heavy metal accumulation in soils is of great concern in agricultural production due to the adverse effects on food quality, crop growth (Ma et al., 1994) and environmental health. Heavy metal bioaccumulation in the food chain can be especially highly dangerous to human health.

Elevated level of heavy metals act as toxicants to flora and fauna of an ecosystem. Earthworms have the ability to bioaccumulate these heavy metals in yellow cells of their body thus help in bioremediation process to eliminate heavy metals from the soil.
