Pesticides used in agricultural produce have great effects on our environment. In vegetables and fruits, pesticides are used to control pests and diseases. Some may still be present as residues in vegetables and fruits. The objectives of this study are to: prevent hazards and produce safe food especially that is daily consumed (fresh vegetables and fruits), and show the risks that threaten human and animal health. Brine shrimp test and thin layer chromatography were used to detect pesticide residues and their toxicity. Toxicity of given samples extracts were qualitatively measured and statistically analyzed to obtain the LC50S. The sample green pepper contain only one pesticide cypermethrin, mango, radish does not contain any components of cypermethrin .Five samples were found to be more toxic with LC50 (74.9, 123, 300.8, 316.2 and 630 ppm). < 1000 ppm comparing to MRL. Four samples show low toxicity with LC50 (1000, 1202, 15135.6, and 223872 ppm) > 1000 ppm. Results suggested that the tomatoes were more toxic, they contain high amount of pesticide residue comparing to MRL. |
