Behaviors of Chromium in Coal-Fired Power Plants and
Coal burning is a main concern for a range of atmospheric pollutants including the environmentally sensitive element chromium (Cr). Cr migrates to the environment through stack emissions and can leach out from solid coal-burning byproducts thereby causing adverse effects on the ecosystem. In this study atmospheric emissions of Cr from six coal-fired power plants (CFPPs) as well as the
