Abstract

The effect of industrial pollution on soil respiration measured in situ has been studied along two gradients formed by emissions from large copper smelters: the Middle Ural Copper Smelter (spruce-fir forests) and Karabash Copper Smelter (birch forests). Pollution has proved to have a slight effect on soil respiration: its rate drops only in the zone of industrial barren. There is no correlation between soil respiration and distance to the emission source, metal contents in the litter, or litter acidity. A hypothesis is proposed that this may be due to a shift in the ratio of the root and microbial components of respiration in the pollution gradient.
