The process of bioremediation entails altering
the surrounding environment to promote the
development of microorganisms that degrade the
intended contaminants in a polluted medium, such as
soil, water, or subsurface material. The environment's
concentration of heavy metals is influenced by
anthropogenic or natural factors. Industries, electronic
trash, and ore mining are examples of anthropogenic
activities which lead to contamination of heavy metals
like cadmium, chromium, lead, mercury, thorium, and
uranium that cannot be biodegraded. Bioremediation
procedures, on the other hand, have the potential to
minimize the mobility of these materials in the
subsurface, hence lowering the risk of environmental
exposure. Due to runoff, heavy metals from these causes
are mostly prevalent in water sources, where they are
absorbed by marine fauna and plants which leads to
ecological and biological disarrays.
