For each occupation, the prevalence of exposed workers within the occupation (%), and the level of exposure (mg/m³), is given. The number and percentage of men, respectively, women in each occupation in the census of 1980 is also shown. Occupations are coded according to the Swedish version of the International Standard Classification of Occupations from 1958 (ISCO58).
*Examples of groups exposed to RCS include workers in the production of sanding discs and paper, abrasives, and insulation material.
