在位于马里兰州、华盛顿和北卡罗来纳州的鱼市和大型连锁超市采集野生捕捞和养殖鱼片，测量其多溴联苯醚（PBDE）、多氯联苯（PCB）和多氯二苯并二恶英/二苯并呋喃（PCDD/Fs）水平。多氯联苯和多溴二苯醚在野生蓝鱼鱼片中的浓度最高（分别为800和38纳克/克湿重），在野生银鲑鱼片中的浓度最低（分别为0.35和0.04纳克/克）。多氯联苯和多溴二苯醚的浓度水平（纳克/克湿重）从蓝鱼（中位数为200和6.2）到岩鱼（中位数为66和4.7）依次下降，养殖鲑鱼（中位数为9.0和1.1）次之，野生鲑鱼最低，多氯联苯和多溴二苯醚的浓度分别为4.0和0.3纳克/克（多氯联苯是25种同系物的总和）。22份鱼片中的氯代联苯（CB）-153和溴化二苯醚（BDE）-47水平相关，Pearson相关系数为0.94。蓝鱼、岩鱼（条纹鲈鱼）、野生捕捞和养殖鲑鱼均显示出不同的CB-153和BDE-47线性回归斜率，分别为7.5、2.7、0.97和1.5。Wilcoxon秩和检验显示，养殖鲑鱼和所有野生鲑鱼物种之间的CB-153/BDE-47比率没有显著差异，但蓝鱼和岩鱼、养殖鲑鱼或野生鲑鱼之间的差异很大。爱思唯尔公司出版
Wild caught and farm-raised fish fillets collected in fish markets and large-chain super markets located in the Maryland, Washington, DC, and North Carolina were measured for their polybrominated diphenyl ether (PBDE), polychlorinated biphenyl (PCB), and polychlorodibenzo-p-dioxins/dibenzofurans (PCDD/Fs) levels. PCB and PBDE concentrations were the highest in a wild bluefish fillet (800 and 38 ng/g wet weight, respectively) and the lowest in wild Coho salmon fillet (0.35 and 0.04 ng/g, respectively). Levels for both PCBs and PBDEs in ng/g wet weight decreased from bluefish with medians of 200 and 6.2, to rockfish 66 and 4.7, followed by farmed-raised salmon with 9.0 and 1.1, with the lowest in wild salmon, 4.0 and 0.3 ng/g for PCBs and PBDEs, respectively (PCBs are the sum of 25 congeners). The chlorinated biphenyl (CB)-153 and brominated diphenyl ether (BDE)-47 levels correlated in the 22 fish fillets with a Pearson correlation coefficient of 0.94. Bluefish, rockfish (striped bass), wild caught and farm-raised salmons all showed different linear regression slopes between CB-153 and BDE-47 of 7.5, 2.7, 0.97, and 1.5, respectively. A Wilcoxon rank sum test showed no significant difference in the CB-153/BDE-47 ratios between farmed raised and all species of wild salmon combined, but was significant between bluefish and rockfish, farmed raised salmon or wild salmon.
