**2.9 Health effect of heavy metals**

Heavy metals like mercury vapor, lead, chromium, and cadmium residue are known for their bioaccumulation and biomagnification properties. Bioaccumulation is the kinetic property of the chemicals in which metabolism and excretion of certain elements are difficult and result in accumulation in specific tissues and organs of the

human body system. An increase in the concentration of those heavy metals when they came across the complex food chain is termed as biomagnification.

Studies have proved that Mutagenic and carcinogenic effects are common health effects related to heavy metals [4]. Moreover, brain damage, respiratory illnesses, cardiovascular disease, and deaths can be attributed as a result of it.
