PM<sub>2.5<\/sub> are particles less than 2.5 microns in diameter).\u00a0 Fine particulate matter is associated with respiratory failure and promotes lung cancer.<\/p>\n<p>Similarly, during the 1950s, when China subsidized the use of coal for heating in cities north of the Huai River, but not those to the south, subsequent levels of cardiorespiratory mortality strongly reflected this division.\u00a0 Levels of PM<sub>10<\/sub>\u00a0were 42 ug\/m<sup>3\u00a0<\/sup>(46%) higher north of the river, and human life-span was reduced by an average of 3.1 years, largely through increased occurrence of cardiovascular disease. \u00a0\u00a0For studies in Beijing, where PM<sub>2.5<\/sub>\u00a0exceeded 115 ug\/m<sup>3<\/sup>\u00a0for more than 6 days, the excess risk of mortality (mortality above expected levels) was about 40%.<\/p>\n<p>The new work indicates that particles from coal-fired power plants are more deadly than those from other sources of fine particles, including forest fires and ammonium-based nitrogen fertilizers.\u00a0 Sulfur dioxide emissions were used to estimate fine particulate matter from coal, which often forms by atmospheric reactions involving SO<sub>2<\/sub>.<\/p>\n<p>Mercifully, a few years ago, the EPA directed electric utilities\u2014much to their objection\u2014to remove fine particles from smokestack emissions. Regionally, in North Carolina, studies by Drs. Julia Krauchanka and H. Kim Lylerly of the Duke University Medical Center found lower rates of mortality after the passage of the Clean Smokestacks Act. \u00a0The science was right, and the air we breathe is much cleaner for it.\u00a0 There is nothing beautiful about coal.<\/p>\n<p>&nbsp;<\/p>\n<p>References<\/p>\n<p>Ebenstein, A., M.
