Residues of BHC (benzene hexachloride) and DDT (dichloro diphenyl trichloro ethane) were detected in 391 samples of vegetables and fruits. A total of 373 sample were lying below the tolerance limit while 18 sample shown comparatively higher value for BHC & DDT. For six samples these values found exceedingly high in comparision to tolerance limit of 0.15 and 1.25 ppm. as recommeneded by WHO/FAO.
