美国ACGIH自1984年开始建议采用生物接触指标(Biological Exposure Index,BEI),在其1984—1985年拟制订的生物接触指标中列出了化学物质6种、监测指标17种。在1985—1986年的表中新增加化学物质4种、监测指标8种,共计列出化学物质10种、监测指标25种。1984—1985年表中原有化学物质生物接触指标的有关规定也略有更动,本文附表中连同新增订的项目一并列出供参考。
Since 1984, ACGIH has recommended the use of Biological Exposure Index (BEI), which lists 6 chemical substances and 17 monitoring indicators in the bio-contact indicators to be formulated in 1984-85. In the table of 1985-1986, four kinds of new chemical substances and eight kinds of monitoring indicators were newly added, of which 10 kinds of chemical substances and 25 kinds of monitoring indicators were listed. The relevant provisions of the original biological indicators of chemical substances in the table from 1984 to 1985 have also been slightly changed, and are listed in the attached table together with the newly added items for reference.
