多氯二苯并二恶英（PCDDs），多氯二苯并呋喃（PCDFs），共面多氯联苯（coPCBs），和多溴联苯醚（PBDEs）的水平进行了测量，在2000年从旧金山弗朗西斯科湾和2001年从加州海岸收集的鱼。这些样本是来自不同地理区域、大小相当的鱼的可食用部分（带皮、去皮或整个身体减去头部和内脏）的复合物。对65个复合样品进行了多氯二苯并对二恶英/多氯二苯并呋喃/多氯联苯混合物分析，对43个复合样品进行了多溴二苯醚分析。在所有采样区域的所有鱼类中，BDE 47、BDE 99、BDE 100、BDE 153和BDE 154的平均浓度总和为302纳克/克脂重，BDE 47 > BDE 100 > BDE 99，BDE 154 > BDE 153。对于所有取样地区所有物种的所有鱼类，多氯二苯并对二恶英/多氯二苯并呋喃国际毒性当量的平均值为33.1皮克/克脂。对于三种coPCB（77、126、169），所有采样区域所有物种的所有鱼类的平均毒性当量为109皮克/克脂质。多氯二苯并对二恶英/多氯二苯并呋喃/coPCB和多溴二苯醚的最高浓度出现在人口密集的弗朗西斯科湾、洛杉矶地区和圣地亚哥湾。(c)2005爱思唯尔有限公司保留所有权利。
The levels of polychlorinated dibenzo-dioxins (PCDDs), polychlorinated dibenzo-furans (PCDFs), coplanar polychlorinated biphenyls (coPCBs), and polybrominated diphenyl ethers (PBDEs) were measured in fish collected from San Francisco Bay in 2000 and from the California coast in 2001. The samples were composites of only the edible portions of the fish (skin on, skin off, or whole body minus head and guts) of comparable size and from distinct geographical areas. Sixty-five composite samples were analyzed for PCDD/PCDF/coPCBs, and 43 composite samples were analyzed for PBDEs. For all fish of all species from all sampling areas, the mean concentration of the sum of BDEs 47, 99, 100, 153, and 154 was 302 ng/g lipid weight, with BDE 47 > 100 > 99 similar to 154 > 153. For all fish of all species from all sampling areas, the mean PCDD/PCDF International Toxic Equivalent (I-TEQ) was 33.1 pg/g lipid. For the three coPCBs (77, 126, 169), the mean I-TEQ for all fish of all species from all sampling areas was 109 pg/g lipid. The highest concentrations of both PCDD/PCDF/coPCBs and PBDEs were found in the highly populated areas of San Francisco Bay, the Los Angeles area, and San Diego Bay. (c) 2005 Elsevier Ltd.
