Coking workers are regularly exposed to coke oven emissions, which consist primarily of polycyclic aromatic hydrocarbons and volatile organic compounds. This study measured the workers' exposure to the benzene soluble fraction of total particulates (BSF). The study population consisted of 88 coking workers as an exposure group and 59 referents. Personal breathing-zone samples of BSF and total particulates were taken from all study subjects for 3 consecutive days. The highest BSF concentrations were found among the topside oven workers (geometric mean; range) (microgram/m3): lidman (515; 72-18, 181), tar chaser (432; 51-4334), and larry car operator (185; 55-649). The lowest was 7 micrograms/m3 in the referents. Among the samples at the topside oven 84% exceeded the Occupational Safety and Health Administration standard (150 micrograms/m3 BSF). The percentage of BSF in total particulates varied across job classifications, ranging from 0.3% in wharfmen to 24% in tar chasers. Area sampling indicated that the BSF concentration at the topside area was sixtyfold higher than that at the administrative area, which was approximately 2 km from the coke oven plant.
炼焦工人经常接触焦炉排放物，这些排放物主要由多环芳烃和挥发性有机化合物组成。本研究测量了工人对总颗粒物中苯可溶部分（BSF）的接触情况。研究人群包括88名炼焦工人作为暴露组和59名对照者。连续3天从所有研究对象采集个人呼吸带的BSF和总颗粒物样本。在炉顶工人中发现了最高的BSF浓度（几何均值；范围）（微克/立方米）：炉盖工（515；72 - 18181）、焦油清理工（432；51 - 4334）和拉里车操作员（185；55 - 649）。对照者中最低为7微克/立方米。在炉顶样本中，84%超过了美国职业安全与健康管理局标准（150微克/立方米BSF）。总颗粒物中BSF的百分比在不同工种间有所不同，从码头工人的0.3%到焦油清理工的24%不等。区域采样表明，炉顶区域的BSF浓度比距离焦炉厂约2公里的行政区高60倍。
