Abstract
Various chrysolite-asbestos from Canada and Russia, asbestos plate and, dry as well as wet manufactured asbestos, were analyzed for Hg, Fe, Eu, La and K by the neutron activation method. Following concentration values were found: Hg 0.01–0.46 ppm, Fe 4818–32738 ppm, Eu 0.02–0.125 ppm, La 0.061–0.874 ppm, K 14.829–358.5 ppm. Statistically significant differences /t=0.05/ in Hg, Fe, Eu, La and K contents were found in the different asbestos samples. The concentration of Hg, Fe, Eu in Italian asbestos were considerably higher than in Canadian chrysolite. High Concentration of La, K were found in Austrian asbestos plate.
