  • The applicability of Raoult's Law for determining the fate of oxygen and sulphur heterocyclic compounds was established by testing a Raoults Law model against coal tar samples from two former manufactured gas plant (FMGP) sites. The model used was based on octanol-air partitioning coefficients (i.e. KOA values) and, despite all coal tars studied showing non-ideal behaviour, proved adequate for predicting heterocycle behaviour once model values were scaled up or down. Results from the first case study, at a FMGP in SW England, highlighted a correlation between those samples which did not follow the same linear Raoult's Law trend and areas where different contamination had occurred. Furthermore, heterogeneous microbial activity, established from variations in redox potential, correlated with areas identified as reflecting different contaminant signatures. Results from the second case study, at a FMGP site in Central Scotland, also show possible microbial influences on Raoult's Law.
