Pesticide residues in air from coastal environment, South India

Chlorinated pollutants are transported through atmosphere. India is one of the point source countries for these pollutants [I]. In this study the concentration of DDT and HCH were evaluated in air from a tropical coastal environment (at parangipettai - southeast coast of India). DDT and HCH ranged in concentrations from 0.16 to 5.93 ng m-3 and 1.45 to 35.6 ng m-3 respectively. The ban on DDT in agriculture is reflected from the low residue levels recorded, predominantly by metabolites other than the parent compounds.[/b]
