Volatilization half-lives from soil were calculated to be 0.2-0.5 days. Estimated losses of VC (after one year under a 1 m soil cover) ranged from 0.1-45%, depending on soil type. Soil sorption coefficients estimated from physicochemical data indicate a low sorption potential and therefore a high mobility in soil. Another important distribution route is leaching through the soil into groundwater where VC may persist for years.
