Heavy Metals in Particulate Matter

        At the majority of monitoring stations, heavy metals concentrations in atmospheric aerosol are lower than in 1996. This data applies to the majority of heavy metals with the exception of the Chopok station where only a decrease in the concentrations of copper, zinc and vanadium was recorded.
