美国ACGIH制订的《1985～1986年作业环境中化学物质阈限值》与前一版(1984～1985年)比较,又有一些变动。现将其中增订、修订和拟修订的阈限值分别列于表1和表2。(1984～1985年阈限值见《卫生标准年刊》第二期第170～184页和《工业卫生与职业病》1985年第3期195～199页)。 There are some changes in the “Threshold for Chemical Substances in Operating Environment 1985-1986” formulated by ACGIH in the United States compared with the previous edition (1984-1985). Now set forth in the revised, revised and proposed thresholds are listed in Table 1 and Table 2, respectively. (Threshold limits from 1984 to 1985 can be found in “Annals of Health Standards,” No. 2, pp. 170-184, and Industrial Hygiene and Occupational Diseases, 1985, No.3, 195-199.)
