Assessing the long‐range transport potential of polybrominated diphenyl ethers: A comparison of four multimedia models
Abstract Data from a comprehensive literature search of environmentally relevant physical‐chemical properties for nine poly‐brominated diphenyl ethers (PBDE), ranging from a monobrominated congener to the fully brominated decabromodiphenyl ether, were evaluated and adjusted to achieve both internal...
