Beryllium, pollution control

Control Techniques for Beryllium Air Pollutants," EPA Pub. No. AP-116. U.S. Environmental Protection Agency, Research Triangle Park, NC, 1973. 

Beryllium and mercury were two of the three air pollutants promulgated as hazardous by the EPA in 1973 and subject to stringent controls (30). While coal combustion releases these elements to the atmosphere, EPA, on the basis of available information, held that this source did not generate sufficient concentrations to be considered hazardous even under restrictive dispersion conditions (29, 31). Coal combustion is thought to be a significant industrial source of atmospheric As (13), Bi (14), Cd (32), FI (33), Hg (3), and Ni (34).
