Emissions of trace elements from coal fired power plants

摘要: Elemental compositions of the coal, various ash fractions and suspended particles in stack Chalk Point (coal fired) power plant southern Prince George's County, Maryland have been measured by instrumental nuclear activation methods. Similar analyses were performed on ambient particulate samples collected at ground level a network stations near with mobile sampling vehicle equipped an SO/sub 2/ analyzer condensation nuclei counter to detect plume. This particular appears cause less enrichment moderately volatile elements (with respect input coal) than plants studied other US groups. The factors earth's crust) most emitted are rather similar values observed for background area. Thus, emissions from raise concentrations uniformly without greatly altering pattern relative concentrations. 7 references, 2 figures, 1 table.
