Exposure to polychlorinated biphenyls and organochlorine pesticides through traditional food resources was examined for Arctic Indigenous women living in two cultural and environmental areas of the Canadian Arctic--one community representing Baffin Island Inuit in eastern Arctic and two communities representing Sahtú Dene/Métis in western Arctic. Polychlorinated biphenyls, toxaphene, chlorobenzenes, hexachlorocyclohexanes, dichlorodiphenyltrichloroethane, chlordane-related compounds and dieldrin were determined in local food resources as normally prepared and eaten. Quantified dietary recalls taken seasonally reflected normal consumption patterns of these food resources by women in three age groups: 20-40 y, 41-60 y and > or = 61 y. There was wide variation of intake of all organochlorine contaminants in both areas and among age groups for the Sahtú. Fifty percent of the intake recalls collected from the Baffin Inuit exceeded the acceptable daily intake for chlordane-related compounds and toxaphene, and a substantial percentage of the intake records for dieldrin and polychlorinated biphenyls exceeded the acceptable or tolerable daily intake levels. Primary contributing foods to organochlorine contaminants intake for the Baffin Inuit were meat and blubber of ringed seal, blubber of walrus and mattak and blubber of narwal. Important foods contributing organochlorine contaminant to the Sahtú Dene/Métis were caribou, whitefish, inconnu, trout and duck. The superior nutritional benefits and potential health risks of traditional food items are reviewed, as are implications for monitoring organochlorine contaminant contents of food, clinical symptoms and food use.
研究了加拿大北极地区两个文化和环境区域的北极原住民妇女通过传统食物来源接触多氯联苯和有机氯农药的情况——一个社区代表北极东部的巴芬岛因纽特人，两个社区代表北极西部的萨胡图戴内/梅蒂斯人。对当地正常加工和食用的食物资源中的多氯联苯、毒杀芬、氯苯、六氯环己烷、滴滴涕、氯丹相关化合物和狄氏剂进行了测定。按季节进行的定量饮食回忆反映了三个年龄组（20 - 40岁、41 - 60岁和≥61岁）妇女对这些食物资源的正常消费模式。在萨胡图地区的两个区域以及不同年龄组中，所有有机氯污染物的摄入量差异很大。从巴芬因纽特人那里收集的50%的摄入量回忆超过了氯丹相关化合物和毒杀芬的每日可接受摄入量，狄氏剂和多氯联苯的大量摄入量记录超过了可接受或可耐受的每日摄入量水平。巴芬因纽特人摄入有机氯污染物的主要食物来源是环斑海豹的肉和脂肪、海象的脂肪和鲸皮以及独角鲸的脂肪。对萨胡图戴内/梅蒂斯人来说，导致有机氯污染物摄入的重要食物是驯鹿、白鲑、湖白鲑、鳟鱼和鸭子。本文回顾了传统食物的卓越营养益处和潜在健康风险，以及监测食物中有机氯污染物含量、临床症状和食物使用情况的意义。
