||The Public Health Institute of Chile carried out an evaluation of the level of exposure of workers to silica in the country. 132 companies involved in various fields of industry were assessed, from which a total of 394 air samples were analyzed. It was found that 35% of the samples exceeded the weighted average permissible limits . The percentage of workers with a high probability of exposure to silica (working more than 30h per week in the presence of silica) was estimated using a job-exposure matrix developed by industrial hygiene experts. It is concluded that 5.4% of the employed workforce has a high risk of exposure to silica. Implications of these findings are discussed.
