Abstract

The aim of the present study was to evaluate the levels of 9 organochlorine compounds (aldrin, hexachlorobenzene, 2,4-DDE, 4,4-DDE, 2,4-DDT, 4,4-DDT, and alpha-, beta-, and gamma-HCH) in butter samples collected in the Eastern, Middle and Western Black Sea Regions of Turkey between October 2009 and June 2010. The liquid-liquid extraction method was used to extract the organochlorine compounds from the samples and the measurements were performed by using a gas chromatograph-electron capture detector system. DDT metabolites, aldrin, hexachlorobenzene (HCB), and alpha-, and gamma-HCH were not detected in the samples but beta-HCH was detected in 3 of a total of 88 samples. In the first period, only one sample from the West Black Sea Region was beta-HCH positive (0.014 mg kg(-1)). The other beta-HCH positive samples collected in Middle and West Black Sea Regions in the second period had a concentration of 0.066 and 0.019 mg kg(-1), respectively. All concentrations of the detected compounds exceeded the legal limits of 0.003 mg kg(-1) for beta-HCH, as prescribed by the Turkish Food Codex, and therefore pose a potential health risk for consumers. The contamination detected is most likely due to the past usage of beta-HCH in agriculture and its long term persistence in the environment. These results strongly suggest that further research should be focused on the detection of pesticide residues in agricultural areas across the nation.
