Mercury in fossil fuels and refined petroleum products are discussed. Mercury emissions from U.S. fossil fuel-fired power plants totaled 61 short tons in 2010 and were emitted in three forms – elemental, oxidized, and condensed on ash particles. The characteristics of these mercury types and issues surrounding their generation and control are presented. The distribution of mercury emissions by type of fossil fuel, combustion technology, and air pollution control device combination is discussed in this chapter. Mercury chemistry in the environment is reviewed. Control technologies for capturing mercury are discussed.
