New Mexico Highway Department Crusher Study.
Data from a New Mexico Highway Department Crusher study from August 23 to 26, 1971 are presented. The author notes that concentrations of respirable dust at a Bernalillo, La Bajada, and Solano crusher location ranged from 340.0 to 0.26 milligrams per cubic meter. Silicon-dioxide (7631869) (SiO2) concentrations ranged from 3.3 to 55.5 percent. Settled dust ranged from 6.4 percent at Solano to 55.5 percent at Bernalillo. Area dust samples ranged from 19.2 percent at LaBajada to greater than 40 percent at Bernalillo. Personnel samples ranged from 3.3 percent at Solano to 54.7 percent at Bernalillo. Threshold limit values ranged from 0.18 at several locations to 1.89 at one Solano location.
