As a result of release to the atmosphere from primary sources and the advection of contaminated air into the atmosphere, the UK environment has become contaminated, with the soil accounting for most of the burden. The model predictions agree reasonably well with measured data from archived soils and fresh water sediment cores, both in terms of temporal trends and predicted concentrations. The use of soil-air fugacity ratios suggests that soil changed from being a net sink through the 1950's until the mid 1980's into a net source during the 1990's.
