| Abstract | ||
| In this study, the residues of commonly used carbamate and pyrethroids pesticides in Libya, (oxamyl, bendiocarb, carbofuran, carbaryl, methomyl, thiocarb, permethrin, deltamethrin , fenvalerate, esfenvalerate , and cypermethrin) in vegetables (tomatoes, cucumber, green pepper, scald, cabbage, lettuce and squash) and fruits (grape, peach, apple and plume) were determined in different seasons (summer 2013, autumn 2013, winter 2014 and spring 2014). HPLC with UV detector was used for quantification, while the quick, easy, cheap, effective, rugged and safe (QUECERS) extraction and purification method was used to isolate the pesticides found in samples. The mean recovery ranged between 75-95% with relative standard deviations ranged between 15%-25%. Results indicated that pesticide residues were found in some monitored fruits and vegetable samples. In all, 93.71% of fruit and vegetable samples analyzed contained no detectable level of the monitored pesticides, 2.81% of the samples gave results with levels of pesticide residues above the MRL, while 4.11% of the samples showed results below the MRL. Carbofuran and oxamyl appear to have health risk associated with them while rest of tested pesticides were found to be under safe limit. The results suggested that the consumers of the eastern area of Libya are exposed to concentration of pesticides that may cause chronic diseases correlated with carbofuran and oxamyl. A future study in a longer period of time would allow obtaining a deeper knowledge about the fulfillment of vegetables and fruits produced in Libya with respect to the use of pesticides and their presence in them | ||
