The predicted environmental distribution of some PCB replacements

Physical and chemical properties which control the environmental distribution of five PCB replacement chemicals (di-isopropylnaphthalenes, phenylxylylethanes, butylated monochlorodiphenyl ethers, isopropylbiphenyls and tetrachloroethylene) have been obtained. These data are used to predict the distribution of these chemicals, a pentachlorobiphenyl and $\text{p,p′}$-DDE in an evaluative environment using a fugacity approach. This simple model gives no information about reactivity or persistence. More complex fugacity models are used to compare these additional features of a di-isopropylnaphthalene PCB replacement with those of a PCB.
