摘　　要：The contents of environmental trace elements in permian coal from Huainancoalmine area and their combustion products were tested by ICP-MS.Analysis and comparativeresearches on the contents of eighteen environmental trace elements in coal andits 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 1 100 ℃ coal ashes, respectively.Combustion temperature, thermodynamics featuresof trace elements and ash content in coal are the main factors that influence theabundance of trace elements in coal and ash.The contents of environmental trace elements in permian coal from Huainan coalmine area and their combustion products were tested by ICP-MS.

Combustion temperature, thermodynamics fea- tures of trace elements and ash content in coal are the main factors that influence the abundance of trace elements in coal and ash.
