摘　　要：Eleven perfluorinated compounds(PFCs) were determined in tissue samples from farmed pigs and chickens(n=143) that were purchased in Beijing in March 2009.The total PFCs mean concentration was the highest in pig liver(3.438 ng g-1 wet weight(ww)),followed by pig kidney(0.508 ng g-1(ww)),pig heart(0.167 ng g-1(ww)),chicken liver(0.098 ng g-1(ww)),chicken heart(0.050 ng g-1(ww)),pork loin(0.018 ng g-1(ww)),and chicken breast(0.012 ng g-1(ww)).Among the PFCs analyzed,perfluorooctane sulfonate(PFOS) was the predominant compound in viscera and muscle of farmed pigs and chickens.In addition,a strong linear correlation(r = 0.932) was observed between the concentrations of PFOS and perfluoroundecanoic acid(PFUnDA) in pig liver.Our preliminary conclusion is that there is little potential risk of exposure to PFCs via the consumption of these products in Beijing.Eleven perfluorinated compounds （PFCs） were determined in tissue samples from fanned pigs and chickens （n=143） that were purchased in Beijing in March 2009.
