Determination of banned organochlorine pesticide levels of some vegetables produced in kastamonu central villages

In this study, forbidden organochlorine pesticide residues in garlic, potato and purslane,which are the most concentrated vegetables in Kastamonu Central Villages, were determined by GC / MS method. Twenty of the 23 OCPs we examined in this study were detected in at least one sample. The most common pesticide residue was p, p'-DDT detected in 10 of 35 samples. In our study, at least 1 pesticide residue was detected in 24 vegetable samples (67%) and no pesticide residue was found in 12 samples. The concentrations of some of the OKP residues (∑DTT, aldrin and dieldrin, methoxychlor, endosulfans, HCHs, heptachlor and endrin) detected in a garlic sample were found to be significantly higher than MRLs. Exceeding the MRLs of this garlic sample is about 28 times (alpha-HCH) to 90 times (aldrin + dieldrin) of these limits.
