Abstract

There has been a significant rise in the levels of heavy metals (Pb, As, Hg and Cd) due to their increased industrial usage causing a severe concern to public health. The accumulation of heavy metals generates oxidative stress in the body causing fatal effects to important biological processes leading to cell death. Therefore, there is an imperative need to explore efficient and effective methods for the eradication of these heavy metals as against the conventionally used uneconomical and time consuming strategies that have numerous environmental hazards. One such eco-friendly, low cost and efficient alternative to target heavy metals is bioremediation technology that utilizes various microorganisms, green plants or enzymes for the abolition of heavy metals from polluted sites. This review comprehensively discusses toxicological manifestations of heavy metals along with the detailed description of bioremediation technologies employed such as phytoremediation and biosorption for the potential removal of these metals. It also updates readers about recent advances in bioremediation technologies like the use of nanoparticles, non-living biomass and transgenic crops.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
