Halogenated derivatives of aromatic and polyaromatic hydrocarbons have been widely used as heat transfer fluids, organic diluents, plasticizers, fire retardants, pesticides, waxes, etc. However, recently it has been pointed out that some of these or their related compounds, of both synthetic and natural origin, can seriously interfere with reproductive function. From the pharmaceutical and environmental viewpoints, the solubilities of these substances are useful to elucidate the movement and persistence in the environment and to estimate the hazard or risk associated with them. Therefore it is important to evaluate the solubilities of, e.g., chlorinated benzenes, biphenyl and dioxins in various media including single, binary and/or multi-component solvents, micellar solutions and polymer solutions.

At first, we started to compile the aqueous solubility data for polychlorinated biphenyls (PCBs) among the halogenated aromatic hydrocarbons, because much attention has been paid to these chemicals as environmental contaminants. We have also compiled the aqueous solubility data of PCBs since 1949 and have started to evaluate them. So far, we have compiled about 40-50 % of the solubility data including those of biphenyl and have paid special attention to the solubility of chlorinated biphenyl isomers.
