Modelling of PCP migration in the environment: Feeding the models with laboratory data
A Besner, P Tétreault, R Gilbert
In 1989, Hydro-Québec began a study program on pentachlorophenol (PCP) to ensure safe use of the product at all stages. One of the aspects of the study is the creation of a predictive system for evaluating the behavior of PCP and oil migration from wood poles to the environment. This system comprises four mathematical models for predicting PCP and oil migration in and on the surface of the pole, in soil and in groundwater, and for predicting runoff. Laboratory experiments aimed at quantifying and supplying the input for each model have been designed. A method of analyzing both PCP and oil in water. wood and soil has been developed. The radial and longitudinal distributions of PCP and oil concentrations have been established for several combinations of wood species and treatments. Laboratory setups and preliminary results are presented.
