0606075VikeslandThis collaborative research project between University of Minnesota and Virginia Polytechnic Institute will investigate the formation of persistent hydrophobic products resulting from the chlorination of wastewater effluent when wastewater is discharged into aquatic environments. Specifically, the PIs propose that the presence of the antimicrobial compound, triclosan, and commonly used flame retardants, polybrominated diphenylethers (PBDEs), in wastewater can lead to chlorinated and brominated dioxins and furans. This project will lead to better information concerning the reactivity of halogenated and hydroxylated diphenylethers during wastewater treatment and in the environment. The combination of fundamental laboratory studies of chemical reactions and field measurements involving two wastewater treatment plants is an important component of the research.

0606075Vikesland明尼苏达大学和弗吉尼亚理工学院之间的这一合作研究项目将调查当废水排放到水生环境中时，废水废水氯化产生的持久性疏水产物的形成。具体而言，PI建议，废水中存在抗菌化合物三氯生和常用阻燃剂多溴二苯醚（PBDE），可能导致氯化和溴化二恶英和呋喃。这一项目将导致更好的信息卤化和羟基二苯醚的反应性在废水处理和环境中。化学反应的基础实验室研究和涉及两个污水处理厂的现场测量相结合是研究的重要组成部分。
