Quick Reference

Emissions from combusted coal, a mixture of several toxic gaseous components and solid particulate matter. Its components include sulfur dioxide, carbonized particles, oily aerosols, and trace amounts of toxic metals such as lead and mercury. Emissions from combusted coal cause air pollution, which has chronic adverse effects on health, and occasional episodes of severe smog, with acute effects including an upsurge of deaths from respiratory and cardiac failure, as in Donora, Pennsylvania, in 1948, and London, England, in 1952.
