Data are compiled and reviewed of the physical-chemical properties of chlorinated benzenes, biphenyls, and dibenzo-p-dioxins and dibenzofurans, which control air-water partitioning, namely vapor pressure, aqueous solubility, and Henry's law constant over the environmentally relevant temperature range of 5-50 degrees C. Recommended values at 25 degrees C, and equations for estimating these properties over the temperature range of 5-50 degrees C are provided. Corresponding enthalpies of phase transition are also reported. (C) 2000 American Institute of Physics. [S0047-2689(00)00203-8].
