Abstract
A new method was developed to evaluate experimentally the load of atmospheric trichloroethylene (TCE) on the contamination of soil by sue of osil (pot soil) packed i n Wagner Pots and polypropylene pots. This method was applied to deter-mine the amount of TCE to the soil through air and/or rain water at a metalware factory where TCE was used as a degreasing agent. It appears that the amount of TCE to the soil through air was much more than that through rain fall, and about 80% of TCE supplied to the soil was volatilized again to the atmosphere. Moreover, only several to some dozen percent of remaining TCE in the pot soil moved more than 12cm deep in the soil for 24 days with precipitation of 26mm.
