Extraction of Multi-Class Pesticide Residues in Mango Fruits ( Mangiferae indica L.): Application of Pesticide Residues in Monitoring of Mangoes.

This article discusses analysis of pesticide residues on mango fruits in India. Five pesticides were measured including parathion methyl, endosulfan, chlorpyrifos, cypermethrin, and fenvalerate using gas-liquid chromatography extraction techniques. According to the authors, mangoes were sampled in the field and also grown under strict integrated pest management controls. The level of detection was determined for each pesticide as peak area five times that of background using the gas chromatograph. The solvent used was found to have a significant role in improving the percent recovery and a mixture of dichloromethane-acetone gave higher recoveries compared to ethyl acetate. Using this protocol only endosulfan was detected in the integrated pest management samples.
