Due to the interest in reducing the benzene exposure limit from 10 to 1 ppm, the benzene exposure data collected since 1977 were compiled and evaluated. Some 38,000 data points representing either time-weighted air samples or persons exposed were collected from five industries which produce and/or use benzene and two government organizations. Of the reported data, 87% represented exposure levels of 1.0 ppm or less. Petroleum and chemical operations where elevated exposure levels were reported included petrochemical and bulk loading operations. Benzol and by-product plants in the iron and steel industry showed similar elevated results.
由于人们希望将苯的接触限值从10 ppm降至1 ppm，因此对1977年以来收集的苯接触数据进行了汇编和评估。从五个生产和/或使用苯的行业以及两个政府组织收集了约38000个代表时间加权空气样本或接触者的数据点。在报告的数据中，87%代表接触水平为1.0 ppm或更低。报告接触水平升高的石油和化工业务包括石化和散装装载业务。钢铁行业的苯和副产品工厂也显示出类似的升高结果。
