The main objective of the proposed project is to carry out detailed comparative study of Hg distribution and mobility in soil at 3 contrasting sites. The sites have been selected according to topsoil Hg concentration. The study will include the determination of Hg concentration and speciation in individual horizons of selected soil profiles and sediments. Additionally Hg concentration will be determined in vegetation to evaluate the actual input flux of Hg to ecosystems. Analysis of total Hg will be performed by the AMA-254 Mercury Analyzer. Mercury speciation will be analyzed by means of Hg pyrolysis technique. The proposed project should extend the present knowledge of Hg contamination in the Czech Republic and broaden the research methodology, especially with respect to the Hg speciation in soil. Comparable study has not been recently realized in the CR, although understanding of Hg speciation and migration in environment is essential for assesing the environmental risks for human.
