Determination of endosulfan residues in eggplant (Solanum melongena) by ELISA.
Eggplant samples were analyzed for endosulfan residues using ELISA, a technique recognized as a promising tool for screening environmental contaminants. Calibration curve for endosulfan was standardized using kits developed by CFTRI Mysore. Farm gate samples of eggplant from 12 different locations were analyzed. The matrix effect was removed by charcoal clean-up. The results were compared with gas chromatographic (GC) analysis. The residues in different samples were in the range of 5-226 ppb. Correlation coefficient between the two methods was found to be 0.98.
