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

拟议研究计划的目标是对包括多溴二苯醚(PBDEs)、药品和个人护理产品(PPCP)和纳米材料(NMS)在内的CECs在MWTP过程中的去向和传输进行全面的基础和应用研究。该计划包括三个项目，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，以便为模型的改进和开发提供信息；(2)确定多溴二苯醚对不同MWPT OM大小部分的分配行为，以阐明分配机制并与各种物理化学参数相关联；以及(3)扩展为多溴二苯醚所获得的知识，以研究PPCPs和NMS，包括验证被动有机化学综合采样器。

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.
