Abstract :In this study were determine concentrations of organochlorine pesticides and polychlorinated biphenyls in meat and by-products samples from different markets of Tirana, Albania. Meat and by-products with origin from Albanian farms were sampling in March 2016. Organochlorine pesticides, their residues and PCBs are stable compounds, lipophilic, with toxic properties. These pollutants could found in meat and by-products because of feed, bioaccumulation process and meat treatment processes. Ultrasonic bath extraction assisted with n-Hexane/Dichloromethane (3:1) as organic solvent and two clean-up steps have been used for analytical treatment of meat and by-products samples. The quantitative analysis of organochlorine pesticides and PCBs were performed by the gas chromatography method with electron capture detector. Analytic steps were based in EN 1528 Method. The profiles of detected pesticides were: Endosulphanes > HCHs > Aldrines > Mirex > Methoxychlor > DDTs. PCB 28, the volatile PCB marker was the main congener for all analyzed samples. In a large number of samples were identified organic pollutants as a result of their previous uses, degradation processes, atmospheric deposition etc. Their levels do not exceed the rates set for them, but should serve as alert for institutions to conduct ongoing controls in foods because it is directly related to the health of consumers.Keywords : Organochlorine pesticides, PCBs, Meat samples, Gas chromatography
