Chemistry and Behavior

Halogenated Alkanes


Table 1 presents common physical/chemical properties of the profiled halogenated propanes. Both of these chemicals are expected to be highly mobile in the subsurface. Neither is expected to bioaccumulate. Although both are subject to anaerobic biodegradation, neither is expected to biodegrade in an aerobic environment (Cohen and Mercer 1993).
