Assessment of potential human health risk due to heavy metal contamination in edible finfish and shellfish collected around Ennore coast, India

This study aims to estimate anthropogenic sources of pollutants such as heavy metals that pollute or poison the commercial marine finfish and shellfish present around the Ennore coastal area and to identify, quantify and manage the associated risks for the betterment of society. The levels of toxic...

Description
Summary:This study aims to estimate anthropogenic sources of pollutants such as heavy metals that pollute or poison the commercial marine finfish and shellfish present around the Ennore coastal area and to identify, quantify and manage the associated risks for the betterment of society. The levels of toxic heavy metal concentrations from monitoring and surveillance of copper, chromium, cadmium, mercury, lead and zinc heavy metals were estimated from water, sediment and commercial marine finfish and shellfish samples that were collected for study. The individual mean bioaccumulation index (IMBI) and Metal Pollution Index (MPI) values varied between finfish and shellfish. Target hazard quotient (THQ) index values were calculated, and copper and zinc were found to be elevated at levels affecting children in particular. Thus, efforts are urgently needed to resolve the current and potential risks associated with the negative impact of heavy metal intake from seafood on human health. This study attempts to identify levels of metal contamination and corresponding risk factors with regard to human health.
