  • Documented substantially elevated risk of silicosis and autoimmune diseases among workers exposed to levels permitted by the current OSHA exposure limit.
  • Documented a 90 percent reduction in drywall dust emissions (a silicosis risk to construction workers) with the use of commercially available ventilated dry-wall sanders.
  • Documented elevated blood lead levels (exceeding CDC recommendations) among children of construction workers, resulting from contamination of workers and their work clothes.
  • Documented an unrecognized high prevalence of silica exposures among surface miners, leading to preventive measures in industry and by MSHA.
