| 摘 要： | 为了解石河子市住宅中邻苯二甲酸酯(Phthalates,PAEs)的污染特征及PAEs对婴幼儿产生的健康风险.本研究对石河子市采暖季和非采暖季50户住宅降尘中的7种PAEs物质进行检测,利用蒙特卡洛(Monte Carlo)模拟和生理提取实验(PBET)评估了PAEs暴露对0～3岁婴幼儿产生的生殖和癌症风险.结果表明:①不同时期石河子市卧室和客厅降尘中邻苯二甲酸二异丁酯(diisobutyl phthalate,DIBP)、邻苯二甲酸二正丁酯(Dibutyl phthalate,DBP)和邻苯二甲酸二(2-乙基)己酯Bis(2-ethylhexyl)phthalate,DEHP]均为室内PAEs的主要组成物质,占总PAEs的99.5%以上,其中DEHP为首要PAEs物质(浓度中位数值为361～462μg·g~(-1)),DBP次之(浓度中位数值为94.9～166μg·g~(-1));②除DIBP外,采暖季卧室和客厅降尘中各PAEs的浓度均高于非采暖季,且差异具有统计学显著性(p0.05),此趋势对小分子质量的邻苯二甲酸二甲酯(Dimethyl phthalate,DMP)和邻苯二甲酸二乙酯(Diethyl phthalate,DEP)而言更明显,DMP采暖季浓度中位数值:0.36～0.42μg·g~(-1)非采暖季:nd,DEP采暖季:0.65～0.71μg·g~(-1)非采暖季:nd～0.03μg·g~(-1);③利用风险指数(HQ)进行健康风险评估表明,采暖季和非采暖季DBP暴露可能会对0～3岁婴幼儿产生较大的生殖风险(HQ_(DBP )=2.62～5.79);DEHP暴露可能会对0～2岁婴幼儿产生较大的癌症风险(HQ_(DEHP)=3.51～5.22).当考虑生物可及性后,仍有8%～37%的婴幼儿可能存在生殖风险,几乎所有婴幼儿无癌症风险.
