Investigation of the role of organic matter in partitioning of chemicals in the municipal wastewater treatment process

拟议的研究计划的目标是进行全面的基础和应用研究的CEC的命运和运输，包括多溴联苯醚（PBDEs），药品和个人护理产品（PPCPs），和纳米材料（NM）在MWTP过程。该方案包括三个项目，其目标是：（1）评估MWTP模型，以确定必要的物理化学参数和需要进一步了解的分配机制，为模型的改进和发展提供信息;（2）确定多溴二苯醚在各种MWPT OM粒度级中的分配行为，以阐明分配机制并与各种物理化学参数相关联;以及（3）将所获得的关于多溴二苯醚的知识扩展到PPCPs和NM的研究，包括被动有机化学综合采样器的验证。

The goal of the proposed research program is to conduct comprehensive fundamental and applied research on the fate and transport of CECs including polybrominated diphenyl ethers (PBDEs), pharmaceuticals and personal care products (PPCPs), and nanomaterials (NMs) in MWTP processes. The program includes three projects with objectives of: (1) Assessment of MWTP models to determine necessary physicochemical parameters and partitioning mechanisms needed to be further understood to inform model improvement and development; (2) Determine the partitioning behaviour of PBDEs to various MWPT OM size fractions to elucidate partitioning mechanisms and correlate to various physicochemical parameters; and (3) Extend knowledge gained for PBDEs to research PPCPs and NMs including validation of passive organic chemical integrative samplers.
