Description

Dark-brown to black solid dispersed in air;

Sources/Uses

Most common exposures: underground mines; Also exposed are workers handling and transporting coal, e.g., trimming or leveling coal in ships; [Levy, p. 422]

Comments

Chronic exposure to coal dust can cause bronchitis and coal workers' pneumoconiosis (CWP). See "Coal workers' pneumoconiosis." "CWP deaths peaked in 1972 (n=2,910), and then declined more than 4-fold to 703 in 2004." [Reference #1] "In the anthracite coal region, CWP mortality has been declining rapidly. If there is no resurgence in the industry, CWP could disappear in that region by 2030." [Reference #2]
