C1- and C2-halocarbons in soil-air of forests

Abstract

Halogenated methanes, ethanes and ethenes have been determined quantitatively in the soil-air and in the atmosphere in forests of southern F.R.G.; the levels in both compartments are similar for most halocarbons, except for trichloromethane. The concentrations of the latter in soil-air are consistently higher than in the air above the ground, which is most pronounced on a mountain crest with severe tree damage.
