Pesticide Residues in Tomatoes from Greenhouses in Souss Massa Valley, Morocco

Abstract

Eight pesticide residues in tomato samples collected in the area of Souss Massa Valley (Southern Morocco) were analyzed. The detected residue levels ranged from 0.001 to 0.400 mg kg(-1) for dicofol, from 0.003 to 0.170 mg kg(-1) for procymidone, from 0.001 to 0.250 mg kg(-1) for chlorothalonil, from 0.050 to 0.500 mg kg(-1) for bifenthrin, from 0.001 to 0.010 mg kg(-1) for λ-cyhalothrin, from 0.001 to 0.300 mg kg(-1) for cypermethrin, from 0.010 to 1 mg kg(-1) for deltamethrin and from 0.003 to 1.123 mg kg(-1) for endosulfan. European MRL for endosulfan in tomatoes set in 0.500 mg kg(-1), was exceeded in 8 samples, and MRL for deltamethrin set in 0.300 mg kg(-1) for tomatoes was exceeded in 2 samples.
