生物接触指数(Biological Exposure Indices,BEI)是在工业卫生工作中用来指导评价潜在健康危害的参考值。制定BEI的依据为阈限值与生物接触指数文件第六版,1991。《Documentation of Threshold Limit Values and Biological Exposure Indices, 6th Ed., 1991》。 ACGIH自1984年起开始制定化学物质的生物接触指数,其后每年增补和修订一部分。本文摘译的是1991～1992年ACGIH正式通过和拟制订和修订的BEI。目前正在研究建立生物接触指数的化学物质有:丙烯腈、锑、苯、二氯苯、2-乙氧基乙醇、2-乙氧基乙酸乙酯、铅、2-甲氧基乙醇、2-甲氧基乙酸乙酯、二氯甲烷、镍、多氯联苯、合成除虫菊酯、钒。正在研究的其它项目还有:(1)质量控制;(2)药物治疗及疾病对生物学水平的影响;(3)用BEI对接触混合
Biological Exposure Indices (BEI) is a reference value used in industrial hygiene efforts to guide the assessment of potential health risks. The basis for the development of BEI is the Threshold Limit and Biological Contact Index, Sixth Edition, 1991. “Documentation of Threshold Limit Values and Biological Exposure Indices, 6th Ed., 1991”. ACGIH has been developing a chemical exposure index since 1984 and subsequently supplements and revises part of it annually. This article extracts the 1991 to 1992 ACGIH formally adopted and intended to be developed and revised BEI. Chemicals that are currently being established to establish biological contact indices include acrylonitrile, antimony, benzene, dichlorobenzene, 2-ethoxyethanol, ethyl 2-ethoxyacetate, lead, 2- methoxyethanol, Methoxyethyl acetate, methylene chloride, nickel, polychlorinated biphenyls, pyrethroids, vanadium. Other items under study include: (1) quality control; (2) the impact of drug treatment and disease on biological levels; (3)
