        报告中,颜老师围绕多环芳烃的理化性质、毒理危害与暴露风险进行阐述,并结合其课题组自主构建的源解析模型反演美国纽约城市多环芳烃的污染历史状况, 对纽约市多环芳烃污染暴露风险进行深入剖析。 此外,颜教授还介绍了其研究团队在个体黑炭等检测仪器的开发、改进与应用中所取得的重要进展, 以及与国内医疗机构合作开展以美国纽约与中国北京作为典型案例的对比研究, 并深入探讨了两城市空气污染与人体健康风险之间的潜在关系与主要差异。最后,颜教授针对重大环境污染事件——墨西哥湾原油泄漏事件,深入揭示了海洋表层水体及深水多环芳烃污染的迁移转化的影响机制, 并为减少环境中多环芳烃污染提出了重要的几点思考。

颜备战老师简介:

        Dr. Beizhan Yan is mainly focused on two areas: 1) characterizing exposure of pollutants and investigating adverse health effects of these pollutants in urban environments and 2) apportioning contamination sources and assessing environmental impact related to human activities (e.g., the fate of contaminants after Deepwater Horizon Oil Spill and impact of hydraulic fracturing on water and air quality).

The ability to unambiguously identify and measure trace organics is a prerequisite for testing mechanisms that impact their behavior and fate. At LDEO, he has established an organic geochemistry laboratory from scratch with the ability to extract organic contaminants from environmental samples (waters, soils, sediments, aerosols) and biological samples (e.g., fish tissue and human exhaled breath condensate), to conduct purification and separation of organics of interest from the complex mixtures and matrices, and to identify and quantify those compounds using modern chromatography techniques. As he has built up these abilities at LDEO, he has continued his research in Environmental Geochemistry (e.g., source apportionment in the NY metropolitan area) and expanded into other areas, including tracing spilled oil in Gulf of Mexico, bioaccumulation and bioavailability of PAHs, bioremediation of contaminated soil/sediments, and the relationships between indoor and personal exposures to these contaminants and adverse respiratory outcomes related to the exposure among children living in NYC and Beijing, China.
