对焦炉作业环境中多环芳烃（PAHs）浓度、作业工人接触PAHs的量、尿1－羟基芘（1－OH芘）排出水平的调查结果表明，焦炉工人尿1－OH芘排出水平与接触PAHs量呈正相关，吸烟对尿1－OH芘测定影响不明显。因此，尿1－OH芘可望作为评价焦炉工人接触PAHs的生物监测指标．
The PAHs concentration, the amount of PAHs exposed to workers and the level of 1-OHP in the coke oven were investigated. The results showed that the levels of urinary 1-OHP in coke oven workers PAHs exposure was positively correlated, smoking on urine 1-OH-pyrene determination was not obvious. Therefore, urinary 1-OH-pyrene is expected to be used as a bio-monitoring indicator to evaluate the exposure of coke oven workers to PAHs.
