The contents of environmental trace elements in permian coal from Huainan coalmine area and their combustion products were tested by ICP-MS. Analysis and comparative researches on the contents of eighteen environmental trace elements in coal and its combustion product suggest that Se and Cd have a high level of distribution in coals;As, Se, Cd, Sb and As, Se, Cd, Mo, Be, Sb also have a high level of distribution in 815 ℃ and 1100 ℃ coal ashes, respectively. Combustion temperature, thermodynamics features of trace elements and ash content in coal are the main factors that influence the abundance of trace elements in coal and ash.
