摘要
探讨不同岗位暴露多环芳烃(PAHs)情况,结果表明,环境空气中PAHs受岗位影响显著,随暴露程度的加重,PAHs暴露浓度呈明显上升趋势。2、3环的PAHs主要分布在气相中,而4环以上的PAHs则主要存在于PM10中。PAHs相当于BaP当量致癌强度也表明,相对于气相来说,致癌源为PM10,其贡献率为90%。
Studied on personal work post exposure to polycyelic aromatic hydrocarbons （PAHs）, result shows different work post has obvious difference reacted on PAHs with rising concentration. The PAHs of 2 rings is distributed in gas, but PAHs of more than 4 rings exists in PM10 mainly, Resuh shows the carcinogenic source is PM10, namely as to gaseous phase with the contribution rate 90%.
