Mercury translocation in and evaporation from soil. II. Evaporation of mercury from podzolized soil profiles treated with HgCl2 and CH3HgCl
Mercury evaporation from soil columns of an iron humus podzol treated with various amounts of HgCl2 and CH3HgCl was measured over 3500 h. The effects of rain acidity, rain duration, and rain intensity were investigated. Hg evaporation from CH3HgCl‐treated soil columns seems to be a biologically determined process. Hg evaporation from HgO2‐treated soil probably is mainly an abiotic process, following a pseudo first‐order reaction with rapidly decreasing evaporation rate due to a decreasing amount of available Hg. The added Hg compounds were transformed to highly volatile Hg0 and/or (CH3)2Hg. The Hg evaporation rate decreased with increasing rain acidity, which may cause accumulation of Hg in the soil. No effects of rain duration and rain intensity were found.
