The levels of six polychlorinated biphenyl congeners (PCBs) were evaluated in 55 samples of meat (bovine and pork) and meat products (sausage, hot dog sausage, bologna sausage, canned export meat and salami) from 11 cities of the state of Rio Grande do Sul, Brazil, between July and August 2002. PCB congeners were found (in fat basis) in the following rank 52 (5.18 ng/g) > 180 (1.69 ng/g) > 10 (1.35 ng/g) > 28 (1.19 ng/g) >153 (0.47 ng/g) >138 (0.43 ng/g), with a summation SigmaPCB amounting to 10.30 ng/g. Meat products had higher PCB levels than meat. PCB levels in samples followed the rank: mixed meat products > pork meat > bovine meat. These results indicate the presence of PCBs in food samples from Rio Grande do Sul, Brazil, but the levels found were well below the maximum level established for animal food products in Brazil (3000 ng/g fat). Only one sample exceeded the maximum level established by the European Community (200 ng/g fat). This is the first paper describing background concentrations of PCBs in meat and meat products from Brazil.
2002年7月至8月期间，对巴西南里奥格兰德州11个城市的55份肉类（牛肉和猪肉）及肉类制品（香肠、热狗肠、博洛尼亚香肠、出口罐装肉和萨拉米香肠）样本中的6种多氯联苯同系物（PCBs）含量进行了评估。以脂肪计，PCBs同系物的含量排序如下：52（5.18纳克/克）>180（1.69纳克/克）>10（1.35纳克/克）>28（1.19纳克/克）>153（0.47纳克/克）>138（0.43纳克/克），多氯联苯总量ΣPCB为10.30纳克/克。肉类制品中的PCBs含量高于肉类。样本中PCBs含量排序为：混合肉类制品>猪肉>牛肉。这些结果表明巴西南里奥格兰德州的食品样本中存在PCBs，但所测含量远低于巴西规定的动物食品最高限量（3000纳克/克脂肪）。只有一个样本超过了欧盟规定的最高限量（200纳克/克脂肪）。这是第一篇描述巴西肉类及肉类制品中PCBs背景浓度的论文。
