Abstract

The objective of the present study was to determine the pesticide residues in fresh vegetables and ruits. Total of 35 samples including fruits (grape, banana, apple, and guava) and vegetables (tomato, brinjal, and cucumber) from three sampling locations Kancharapara, Jaguli and Barasat were studied. Analysis was carried out by Gas Chromatograph coupled with Mass spectrophotometer (GC-MS) and four major pesticides belonging to synthetic pyrethroid and carbamates were identified. The identified pesticides were Aldicarb, Allethrin, Oxamyl and Molinate. The typical percent recoveries were found to be 95 ± 10 for all pesticides. The average level of pesticides concentration of Aldicarb, Allethrin, Oxamyl and Molinate were 0.36, 3.93, .18 and 2.83 ppm respectively for fruits and 0.86, 5.57, 5.55 and 3.67 ppm respectively for vegetables were found. The concentration of three pesticides was above the prescribed maximum residue levels (MRL) except for aldicarb. The high levels of pesticide residues found in this study imply the need to enforce effective regulations regarding the appropriate use of pesticides.
