Abstract:

Pesticides residues contamination is one of the major concerns worldwide, which influences the practical and structural integrity of an environment. Their direct and indirect effects on human health cannot be avoided. The purpose of this study was to highlight the traceability of organochlorine pesticide residues on the food chain: feed - fatty tissue, - meat - meat products. All samples were collected from a slaughter house in Cluj County. The fat and meat samples were stored at 18 °C temperature and the feed samples at room temperature. The gas chromatographic method was followed for identification of organochlorine pesticide residues from vegetable and animal food. In the collected samples, the largest weight had DDT and its metabolites (375.9 ng/g fat) and HCH isomers (277.7 ng/g fat) site by chlordane, heptachlor, heptachlor epoxide, as well as endosulfan. Regarding the contents of â??DDT it can be observed that the largest amount was found in fatty tissue, mainly being bioaccumulated in mesenteric tissue and organs. This may be due to the cumulative effect of DDT and its metabolites in fatty tissues and organs (liver, kidney, heart, and spleen) reported also by Covaci et al. In the case of â?? HCH was found a preferential accumulation in meat followed by organ, fatty tissue and meat products. Regarding organochlorine pesticide residues traceability, it can be concluded that their presence in feed make them to be presented both in the adipose tissue, organs and muscle tissue, as well as in the meat products. Codification of the samples was as follows: feed samples Fj; fatty tissue samples: fat O, bacon S, caul M; meat samples: pork neck CF, chops CO, leg P; samples of paste composition: paste composition for frankfurters and rosy sausages CFP, paste composition for semi-smoked samples PCS; and meat products samples: frankfurters CW, rosy sausage PZ, salam varÄ? salami SV, smoked sausages CA, trandafir sausages CT, and liverwurst LB.
