Pollution due to persistent pesticides is not a regional but a global problem. Organochlorine pesticides are persistent chemicals, stored and accumulated in the tissues of a wide variety of invertebrates and vertebrates including marine species. In the present study the organochlorine residues HCHs, DDTs and PCBs were measured in different trophic groups of birds (scavengers, inland piscivores, coastal piscivores, insectivores, granivores and omnivores) collected from Tamil Nadu Coast, India… 

Is current information on organochlorine exposure sufficient to conserve birds in India?

There is a clear deficit of data on OC concentrations and sublethal effects that needs to be addressed to understand the status of OC exposure, spatio-temporal trends and potential impacts in Indian avifauna.

Environmental contamination due to persistence of pesticide residues is gaining worldwide attention. Exposure to pesticide residues can represent a potential risk to any organisms. The residue level

Characteristic trend of persistent organochlorine contamination in wildlife from a tropical agricultural watershed, South India

The residue levels in fish measured in the present study were generally comparable to values reported from other locations, which suggests that the bioavailability of contaminants to the aquatic fauna is less due to the smaller flux and shorter residence time of these chemicals in the tropics.

Eight species of birds were collected from three agricultural areas with long histories of pesticide use in northwestern Mexico and concentrations of OCs and PCBs were higher for Mexicali than for Yaqui and Culiacan.

Accumulation Features of Polychlorinated Biphenyls and Organochlorine Pesticides in Resident and Migratory Birds from South India

Global comparison of organochlorine concentrations indicated that resident birds in India had the highest residues of HCHs and moderate to high residues of DDTs, and it is proposed that migratory birds wintering in India acquire considerable amounts of H CHs and DDTs.

Transfer of chlorinated biphenyls to Antarctica

Equivalent levels and ratios of these pollutants in species resident north and south of the Convergence indicate atmospheric, rather than oceanic, transport to Antarctica.
