Over-dependence on coal results in the emission of Hazardous Trace Elements (HTEs) including selenium (Se), mercury (Hg), lead (Pb), arsenic (As), etc., from Coal-Fired Power Plants (CFPPs), which are the major toxic air pollutants causing widespread concern.
This study focused on the local environmental impact of a coal-fired power station with a net capacity of 600 MW e . The atmospheric emissions of numerous possible flue gas components were calculated using the KEMA TRACE MODELR. The STACKS model was used to calculate annual average immission levels or ground-level concentrations.
Trace element simulation and validation of model predictions for the elements Hg, As, Se, Cd and Pb have recently been undertaken for the ® FBDB™…

An analysis of a historical data base (1981-present) shows that the typical trace element concentration variability (percent relative standard deviation (PRSD)) for commercial coal from a single mine was 10–20% over that period. Across a broader geographical region in a single seam, the PRSD increased to 20–50%.
This paper identifies the toxic chemicals of greatest significance for the electric utility sector and develops quantitative estimates of the toxic releases reportable to the TRI for a representative coal-fired power plant. Key factors affecting the magnitude and types of toxic releases for individual power plants also are discussed.
