Determination of endosulfan residue in wheat grain and flour by ELISA
Newly developed Enzyme Linked Immuno Sorbent Assay (ELISA) technique has been used for monitoring of wheat grain and flour samples for endosulfan residues. Data indicated that eight samples out of fifteen contained endosulfan residues. The average concentation varied from 0.65-6.1 ppm. ELISA data correlated well with GC analysis with correlation coefficient of 0.98.
