In this study 32 pesticide residues and eight polybrominated diphenlyl ether (PBDE) congeners were measured in nine honey samples from Kahramanmaras, Turkey. A new method based on the best recovery was column extraction with n -hexane/acetone followed by gas chromatography electron-capture detection (GC-ECD), and mass spectrometry (GC–MS). Generally the pesticide levels were low in the honey samples. γ-HCH and PCB 28 were being measured in all honey samples. The sum of HCHs in samples varied between 0.71 and 2.47 ng/g. Malathion, bromophos methyl, cis -HCE, chlordane, endrin, p,p ′-DDE and o,p ′-DDD were not detectable. The mean values of α-HCH and β-HCH were 0.60 and 0.52 ng/g. The mean values of HCB, α-chlordan, trans -nonachlor, cis -nonachlor, Heptachlor, aldrin, bromophos ethyl, trans -HCE, α-endosulfan, β-endosulfan, dieldrin were 0.30, 0.05, 0.14, 0.84, 0.04, 0.06, 2.74, 0.03, 0.09, 0.27, 0.36 ng/g respectively. In none of the samples PBDEs were detected. |
