| 摘 要： | 为研究聊城市冬季PM_(2. 5)中多环芳烃(PAHs)的浓度水平、来源及健康效应,于2017年1～2月对聊城市PM_(2. 5)中的14种PAHs进行分析,利用特征比值法和PCA-MLR模型对其来源及贡献率进行解析,并利用Ba P当量浓度(Ba Peq)和呼吸途径暴露PAHs引发癌症的风险(ILCR)模型进行健康风险评估.结果表明,聊城市冬季PM_(2. 5)中PAHs的平均质量浓度为(64. 89±48. 23) ng·m~(-3),其中Fla、Pyr和Chry的浓度最高,占比分别为15. 5%、12. 8%和12. 7%,且4环PAHs总质量浓度占比最高,春节前与烟火Ⅱ期比其他时期污染较重. PCA-MLR模型分析结果表明,聊城市冬季PM_(2. 5)中PAHs来源主要包括煤炭燃烧、生物质燃烧和机动车尾气.聊城市冬季TEQ平均值为(6. 37±4. 92) ng·m~(-3),ILCR模型评估结果表明,成人的ILCR值高于儿童,二者的ILCR值均处于风险阈值内(10-6～10-4),表明聊城市冬季PM_(2. 5)具有潜在致癌风险.
