Endocrine disrupting chemicals in Hungarian canned foods

The aim of this study was to clarify the worldwide residual levels of organochloride compounds, such as BHC and DDT, which were reportedly concentrated in animal tissues by biological food chains. As a part of the investigation of endocrine disrupting chemicals (EDCs), we had a chance to measure the level of these compounds in Hungarian canned foods.Seven kinds of canned foods were purchased at a market in Budapest, Hungary, and the concentrations of eighteen organochloride compounds (α-BHC; β-BHC; γ-BHC; δ-BHC; p,p'-DDT; p,p'-DDE; p,p'-DDD; o,p'-DDT; heptachlor; heptachlor-epoxide; aldrin; dieldrin; endrin; oxychlordane; trans-chlordane; cischlordane; trans-nonachlor; and cis-nonachlor) were measured.Other than DDT and its metabolites, none of the EDCs were detected (levels <0.4 ppb). DDT and its metabolites, however, were detected in fish, meat and chicken liver pate. One of the DDT metabolites was detected quite frequently: p,p'-DDE was detected at a level of 1.8 ppb in fish soup concentrate, 2.3 ppb in Hungarian luncheon meat, 0.5 ppb in special luncheon meat, and 0.6 ppb in chicken liver pate.Of eighteen organochloride compounds examined, only DDT and its metabolites were detected in fish, animal meat, and animal liver. It is suggested that the DDT contamination in fish and meat is worldwide even after the ban of its use.
