Abstract:
Rice and wheat are one of the most popular cereals crops all over the world. Pesticide contamination is a major concern that has led to current food safety issues and cross border rejection and acceptance of the food commodities. The current research work was done to conduct quality assurance of rice and wheat grains for the presence of banned organo-chlorine pesticides(OCP); ß-HCH (ß-1,2,3,4,5,6hexachlorocyclohexane, chlorothalonil, heptachlor epoxide, 4,4?-DDE (2,2-Bis-(4-chlorophenyl)1,1-dichloroethene), 2,4?-DDD (2-(2-chlorophenyl)-2-(4-chlorophenyl)-1,1-dichloroethane) and a,ß-endosulfan. Grain samples (17 rice, 15 wheat) and 11 soil samples, collected from different areas of Punjab, were analyzed for OCPs residues. Simple extraction methods were used to simultaneously determine the presence of these seven OCPs in grain samples using gas chromatography equipped with electron capture detector. The results showed the presence of OCPs residues in varying amounts in rice and wheat grains samples inspite of the fact that most of them were banned about 40 years ago. The method validation data, as obtained from analyses of fortified rice and wheat samples, resulted in the mean recoveries between 70.4 to 111.5%, limit of detection as 0.001 mg kg-1, limit of quantification as 0.01-0.05 mg kg-1, repeatability limit of 0.755 and reproducibility limit equals 0.779.
