PCBs CONCENTRATIONS IN THREE KINDS OF LIVESTOCK MEAT FROM SHENZHEN, CHINA
Food intake is the main source of exposure to dioxin-like compounds for humans, meat accounts for a large portion in human daily diet. To protect the peoples health and explore the pollution level of polychlorinated biphenyls(PCBs) in meat, 28 samples of three kind of retail livestock meat were investigated. The research included beef, pork and mutton. After extraction, extracts were cleaned up by FMS and analyzed by isotope dilution high-resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS). The results showed that the highest level for the median of DL-PCBs was 0.84 pg WHO-TEQ/g fat in beef, followed by 0.28pg/g fat in mutton, 0.15pg/g fat in pork. In all samples, PCB118 was the greatest contributor to the total contaminated concentration, and PCB126 was the dominant contributor to the TEQ concentration. From the results of dioxin content in six samples exceeded the EU action level limit and four of the six samples also exceeded the EU maximum level limit, PCBs contamination existed in livestock meat products in China, it was suggested that policy decision maker and superviser should pay more attention to this circumstance.
