Collaborative Research: Formation of Polyhalogenated Dioxins and Furans from Triclosan and PBDEs in Rivers

维克斯兰这个由明尼苏达大学和弗吉尼亚理工学院合作的研究项目将调查废水排放到水环境中时，废水流出物氯化产生的持久性疏水产物的形成。具体地说，PIS提出，废水中存在抗菌化合物三氯生和常用的阻燃剂多溴二苯醚(PBDEs)，可能会导致氯化和溴化二恶英和呋喃。该项目将有助于更好地了解卤化和羟基二苯醚在废水处理过程中和环境中的反应性。化学反应的基础实验室研究和涉及两个废水处理厂的现场测量相结合是这项研究的重要组成部分。

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.
