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.
