Chlorinated pollutants are transported through atmosphere. India is one of the point source countries for these pollutants [1]. In this study the concentration of DDT and HCH were evaluated in air from a tropical coastal environmental (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.
