Human milk (497 samples) representing donors from across Canada were analyzed for 24 organochlorine pesticides and industrial chemicals and 40 PCB congeners. PCBs, p,p'-DDE, hexachlorobenzene (HCB), and trans nonachlor were present in all samples. Compared to earlier surveys in Canada, concentrations of most residues determined declined, and were lower than those reported recently in European countries. Although regional differences were minor, residues of PCBs, p,p'-DDE, and trans nonachlor were higher in the Ontario, Quebec, and Eastern regions, and all residues were slightly higher in the Great Lakes Basin compared to the rest of Canada. Concentrations of PCBs, DDTs, HCB, and trans nonachlor were higher in participants who consumed greater than 100 g of fish weekly.
对来自加拿大各地捐赠者的497份母乳样本进行了分析，检测其中24种有机氯农药和工业化学品以及40种多氯联苯同系物。所有样本中均检测出多氯联苯、p,p'-滴滴伊、六氯苯（HCB）和反式九氯。与加拿大早期的调查相比，所测定的大多数残留物浓度有所下降，且低于欧洲国家最近报告的浓度。尽管地区差异较小，但安大略省、魁北克省和东部地区的多氯联苯、p,p'-滴滴伊和反式九氯残留物含量较高，与加拿大其他地区相比，五大湖流域的所有残留物含量略高。每周食用超过100克鱼类的参与者体内多氯联苯、滴滴涕、六氯苯和反式九氯的浓度较高。
