Respiratory effects of exposure to low levels of concrete
Jul 23, 2001 · The average silica content of the dust was 9%. The average cumulative dust exposure was 7.0 mg/m 3 year and cumulative silica exposure was 0.6 mg/m 3 year. Significant associations between exposure to concrete dust and a small lung function (FEV 1 /FVC ratio, MMEF) loss were found, independent of smoking habits and of a history of allergy.
