Water pollution caused due to addition of heavy metals resulting
from the industrial activities is increasing tremendously and is a matter
of global concern. Mining, mineral processing and metallurgical
operations are generating effluents containing heavy metals. The heavy
metals present in the wastewater is persistent and non degradable in
nature. Moreover, they are soluble in aquatic environment and thus can
be easily absorbed by living cells. Thus, by entering the food chain, they
can be bioaccumulated and biomagnified in higher trophic levels also.
The heavy metals, if absorbed above the permissible labels, could lead to
serious health disorders. In light of the facts, treatment of heavy metals
containing industrial effluent becomes quite necessary before being
discharged into the environment.
