The results of the content and distribution of heavy metals and selenium in different types of soils of Ukraine, in protected areas and areas of technogenic pollution are presented. The highest content of selenium (460 micrograms/kg) is set in the soils of the Crimean reserve. Revealed its association with heavy metals – Cu, Pb, Zn, Cr. In respect of territories with development pressure, the selenium content in the soil increased to 1200–1400 micrograms/kg. Just increases in association with the selenium content of heavy metals with respect to the protected territory of 10 times or more. The analytical scheme of ICPMS determination of selenium and its association with heavy metals in soils, plants, fungi have been developed. The technique allows to express and efficiently carry out eco-geochemical monitoring of the environment on the content of toxic elements (Se, Pb, Ni, As) in the range of 0,1 ppb to 100 ppm.
Key words: selenium, heavy metals, ICP-MS analysis.
