Effects of artificial acid rain on microbial activity and biomass

Research output: Contribution to journalArticle

Abstract

The emission of air pollutants which form acid components
in rain and snow represents a threat to natural ecosystems.
Increased leaching of nutrients from soils (ABRAHAMSEN et
al. 1976b), decreased pHvalues in lakes and changes in fish
populations (SCHOFIELD 1976) have been suggested as some of
the consequences of the increased acidity of rain. Scandinavian
coniferous forests are very stable ecosystems, and dramatic
short-term effects due to acid rain are hardly to be
expected. To simulate long-term effects, artificially acidified
rain may be used. We report here decreased microbial
activity and biomass in a Norwegian forest soil treated with
artificially acidified rain.
