Concentration of Heavy Metals in Dominant Moss Species as an Indicator of Aerial Technogenic Load

详细

The concentrations of nickel and copper were determined in mosses Hylocomium splendens and Pleurozium schreberi sampled in 1991 and 2011 at the same sites in the Lapland State Biosphere Reserve located in the impact area of atmospheric emissions from the Severonickel Smelter Combine (Monchegorsk, Murmansk Region, Russia). Both moss species have been confirmed to adequately reflect the levels of aerial technogenic load and can be used equally to monitor environmental pollution from heavy metals. It has been statistically proven that not only the volume of atmospheric emissions of polymetallic dust and the distance to the pollution source affect the concentrations of heavy metals in the studied moss species, but the wind rose and relief are also of importance.
