Abstract

The problem of polychlorinated biphenyls (PCBs) became a national concern in 1971 when several accidental contaminations of foods were reported. Extensive efforts were undertaken by FDA to reduce the residues of PCBs in food. However, the PCB levels in several species of fresh-water fish have raised concern about the PCB residues from environmental contamination, and it is this concern which has prompted a reassessment of the human risk involved from consumption of such fish. The human epidemiology and animal toxicity of PCB exposure are reviewed, as well as risk assessment in general. Specific examples to risk assessment involving extrapolation of animal data to humans, based on several levels of human exposure to PCBs in fish, are presented.

摘要

1971年,多氯联苯(PCBs)问题引起了全国关注,当时有几起食品意外污染事件被报道。美国食品药品监督管理局(FDA)做出了广泛努力,以降低食品中多氯联苯的残留量。然而,几种淡水鱼体内的多氯联苯含量引发了人们对环境污染导致的多氯联苯残留的担忧,正是这种担忧促使人们重新评估食用此类鱼类对人类造成的风险。本文综述了多氯联苯暴露的人类流行病学和动物毒性,以及一般的风险评估。文中还给出了风险评估的具体例子,这些例子基于人类对鱼类中多氯联苯的几种暴露水平,涉及将动物数据外推至人类。
