The U.S. Department of Labor's Occupational Safety and Health Administration
OSHA has released 15 years of data detailing workplace exposures to toxic
chemicals. The data, available on OSHA's Web site, is comprised of measurements
taken during the course of inspections, including exposure levels to the
hazardous chemicals asbestos, benzene, beryllium, cadmium, lead, nickel,
silica, and others. It can offer insights into the levels of toxic chemicals
commonly found in workplaces, as well as how exposures to specific chemicals
are distributed across industries, geographical areas and time.
