【正文】 on of PBDEs has occurred literally everywhere in the environment. In aquatic systems, the majority of the PBDEs are deposited in sediments, particularly those with high degrees of bromination. The basic hypothesis of this proposal is that PBDEs, which have accumulated in the environment over the past four decades, have debrominated in the sediments of heavily contaminated water bodies. Comparison between PBDEs and polychlorinated biphenyls (PCBs) in their production history, congener distribution patterns in mercial products, carbonhalogen bond energy, and the time scale of environmental contamination, etc, supports their hypothesis.

Herek Clack Illinois Institute of Technology In 2021, the . EPA issued the Clean Air Mercury Rule (CAMR), making the . the first country to regulate mercury emissions from coalfired power plants (CFPPs). The CAMR emissions caps are designed to reduce total mercury emissions by 70% by 2021. This project represents a bined experimental and numerical modeling collaboration between research groups at the Illinois Institute of Technology (IIT) and the University of MinnesotaTwin Cities (UM) to provide fundamental understanding of mercury removal processes and to develop enhanced mercury removal processes.
