Abstract

In 1979, widespread distribution of chicken and egg food products and grease contaminated with polychlorinated biphenyl (PCBs) occurred across the United States and as far away as Canada and Japan. The contamination was traced to an accidental leakage of PCBs from a transformer stored in a hog slaughtering plant in Montana. Breast milk analyses showed the PCB absorption had occurred among egg consumers. The episode illustrates the need for heightened vigilance over the fate of PCBs still in use.

摘要

1979年,受多氯联苯(PCBs)污染的鸡肉、蛋类食品及油脂在美国广泛传播,甚至远至加拿大和日本。污染源头是蒙大拿州一家生猪屠宰厂储存的一台变压器意外泄漏多氯联苯。母乳分析显示,食用蛋类的人群体内出现了多氯联苯吸收情况。这一事件表明,对于仍在使用的多氯联苯的去向,需要提高警惕。
