The use of physicochemical data to estimate the fate of chemical pollutants in environmental systems in an easy way is described. This application is presented to students in a series of labs in an environmental chemistry course, which is mainly focused on the chemical behavior of contaminants in the environment. Specifically, physicochemical parameters are used to determine the phase equilibrium distribution of a substance in a closed system. The model is applied to estimate the phase distribution of three organic pollutants, namely, pentachlorophenol, hexachlorobenzene, and hexachlorocyclohexane, in a defined environmental model system.

Our Secondary School editors work hard to distill all the JCE materials to produce a fraction of particular interest to high school teachers. We call it CLIC.
In recent years we have worked hard to better match our advertisers with our readers. When shopping for chemistry education materials, visit our advertisers' WWW sites first.
