摘要
This paper researched geochemistry character, chemical speciation, transportation pattern of selenium and mercury in the coal field circumstance by geochemical method. The results indicated that the contents of Se and Hg were enrichment prominently in atmosphere particles, the abnormity area was accord to the bound of Kailuan coal field. The atmosphere particles and surface water system were the mainly approach of Se and Hg diffusing in the system of coal-atmosphere-soil-surface water system, in the course of which the chemical speciation transformed, a ctivation direction was distinct. The influence area extended 1 200 km2 in the field and its periphery, covered the entire water system flowing the coal field.
