SPATIAL AND TEMPORAL TRENDS OF PERSISTENT TOXIC SUBSTANCES IN INDIA
In the Asian region, Indias role as a major contributor of classical persistent organic pollutants (POPs) has been well known. Indias geographical location, tropical climatic conditions, excessive population, diseases, increasing industrialization and urbanization and heavy usage of several chemicals makes it an area of great concern, while evaluating the global pollution status of persistent toxic substances. The efforts of our institute for the past more than two decades collecting environmental samples (air, water, soil and sediments) and also biological matrices covering mussels, fish, birds, food stuff and terrestrial and marine mammals including human subjects from the coastal areas, metropolitan cities, towns and villages, municipal dumping and e-waste recycling sites for the analysis of classical organochlorines (such as DDTs, HCHs, PCBs, CHLs, HCB), dioxins and furans, brominated flame retardants (PBDEs and HBCDs) and also many trace elements provided us an invaluable data base on the pollution status of India and its role in the global pollution by these chemicals. We explain in this paper, the invaluable insights that could be observed in our results on the possible sources, spatial and temporal variations, transport and distribution, global comparison, risk assessment, etc. of these chemicals on a global scale.
