Thirteen soil samples spreading over many taluks of Mandya and Mysore districts of Karnataka state were collected after DDT spray program and analyzed for DDT and DDE residues using the immunoassay and gas liquid chromatography. Data from ELISA indicated 13 out of 13 samples contained DDE residues, while 8 out of 13 had DDT. The average concentrations of DDT varied from 0.4 to 4 ppm in soil samples, whereas DDE concentration ranged from 0.06 to 0.25 ppm. ELISA data correlated well with GC analysis with regression coefficient of 0.95.
