Mercury stack emissions from U.S. electric utility power plants

The materials flow of mercury in the economies of the United States and the world

“…Although these regulations are not specifically targeted at reductions in mercury emissions at this time, some of the emission control technologies currently employed prevent nearly one-half of the mercury contained in coal from being emitted to the atmosphere (Chu and Porcella, 1995). As stricter regulations are implemented and as mercury is targeted, mercury contributions to the environment from these sources should decrease.…”

Hg Reactions in the Presence of Chlorine Species: Homogeneous Gas Phase and Heterogeneous Gas-Solid Phase

“…The first sampling impinger contained a 0.1% HNO 3 solution and was used to trap the oxidized forms of Hg. 32,33 A set of three other impingers containing 0.4% KMnO 4 /10% H 2 SO 4 were used to trap elemental Hg in the gas phase. 31 The impinger solutions were analyzed to determine the elemental Hg concentration and oxidized Hg species concentration in the gas phase, using CVAA.…”

Combined Theoretical and Experimental Investigation of Mechanisms and Kinetics of Vapor-Phase Mercury Uptake by Carbonacoues Surfaces

“…(24) Chu and Porcella have estimated that 89 ton/year of mercury is emitted to the atmosphere from U.S. coal-fired power plants (CFPPs) in 1990. (25) U.S EPA estimated that about 300 ton/year of mercury was emitted from anthropogenic sources in the U.S. in 1990, with 30 % of total mercury emissions coming from coal fired power plants (CFPPs). (26) The hospital / medical / infectious waste incineration is a common unit operation used for medical waste disposal in the United States and worldwide.…”
