摘要：In this study, organochlorine pesticides (OCPs) and organophosphorus pesticides (OPPs) contamination of wheat cultivated in Konya region and soils of this region were determined. Health risk caused by the consumption of pesticide contaminated wheat was assessed. Totally, 30 soil samples and 21 wheat samples taken from the field and trade center were analyzed for OCPs (a-HCH, P-HCH, y-HCH, 5-HCH, aldrin, dieldrin, heptachlor, heptachlor epoxide, endosulfan I, endosulfan II, endosulfan sulfate, p,p’-DDE, p，p’-DDD, p，p’-DDT, endrin, endrin aldehyde, endrin ketone, methoxychlor) and OPPs (malathion, parathion, methyl-parathion, chlorpyrifos, diazinon). Determinations of OCPs and OPPs were carried out with a GC/MSD (GC, Agilent 6890 N, MSD, Agilent 5973).Maximum concentrations of OCPs in soil samples were found for SHCHs (a-HCH, P-HCH, y-HCH, 5-HCH) and Sendosulfan (endosulfan I, endosulfan II, endosulfan sulfate) in the range of 8.74 - 71.8 ng g-1 and 1.99 - 112 ng g-1, respectively. Malathion and chlorpyrifos were the predominant OPPs in soil and wheat samples. Maximum concentrations of malathion and chlorpyrifos in soil samples were 222 ng g-1 and 556 ng g-1, respectively. Maximum total OCPs and total OPPs in the grain were 2.32 ^g g-1 and 15.4 ^g g-1, respectively. SDDT was found in the range of 20 - 60 ng g-1 in grain samples. Trade center samples exceeded maximum residue limits (MRL) of Turkish Food Codex (TFC) given for P-HCH, y-HCH, SHCH, dieldrin and chlorpyrifos, and field samples exceeded MRL given for a-HCH, P-HCH, XHCH, ^endosulfan, Sheptachlor, and all OPP compounds. There is an acute and chronic consumer health risk due to the consumption of pesticide contaminated wheat, on the basis of aHI and HQ calculation. Besides, prohibited pesticides are obviously still being used in the area.
