A major concern related to the use of coal for electricity production is the release of elements to the environment, both during combustion and from the resulting coal combustion products (CCPs).

Analyses of feed coal and CCPs from an Indiana power plant utilizing coal from the Powder River Basin, Wyo., provided data that characterized the physical and chemical properties of elements in the coal and CCPs, as well as the elements’ modes of occurrence.
