Mercury and other trace elements in Ohio River fish collected near coal‐fired power plants: Interspecific patterns and consideration of consumption risks
Many coal‐fired electric generating facilities in the US are discharging higher loads of Hg, Se, and other chemicals to receiving streams due to the installation of flue gas desulfurization (FGD) air pollution control units. There are regulatory concerns about the potential increased uptake of these bioaccumulative trace elements into food webs. We evaluated the concentrations of As, THg, ...

An analysis of extinction coefficients of particles and water moisture in the stack after flue gas desulfurization at a coal-fired power plant
Two important factors that affect in-stack opacity—light extinction by emitted particles and that by water moisture after a flue gas desulfurization (FGD) unit—are investigated. The mass light extinction coefficients for particles and water moisture, kp and kw, respectively, were determined using the Lambert-Beer law of opacity with a nonlinear least-squares regression method. The ...

Document shows power plant guidelines rule significantly altered in White House review
An Environmental Protection Agency rule proposed in June to regulate discharges of toxic pollutants from power plants was significantly altered during White House review to include additional regulatory options for industry, an EPA document shows. The newly added options are generally seen as less stringent than the initial EPA proposals because they establish lesser numeric effluent limitations ...

Present status and future prospect of clean coal technology in China
Coal consumption accounts for about two thirds of the primary energy consumption in China. High economic growth has brought about a rapid increase of coal consumption. Low-efficiency combustion of a large amount of coal caused coal-smoke related air pollution. The Chinese government put forward plans to develop clean coal technology in the early 1990s, and has listed it as one of the emphases for ...

Formation and emission of fine particles from two Danish pulverised coal fired power plants
ABSTRACT Measuring campaigns at two Danish pulverised coal fired power plants has been performed. The power plants are equipped with the same type og flue gas cleaning devices. The concentrations and chemical compositions of the formed particles were similar for the two plants. The measurements were performed simultaneously at three locations including both total dust measurements and fine ...
