Abstract |
A study of the over-estimate of silica concentration in the workplace air of foundries, due to the presence of other substances detected by infrared spectrophotometry. Significant interference was produced by the following substances (percentages refer to the minimum concentrations of these substances relative to silica that would produce such interference): iron oxide (300%); aluminium oxide (100%); graphite (100%); kaolin (50%); bentonite (100%). |
