Agents fibrogènes et cancérogènes dans les mines d’or et de fer du Québec - Étude exploratoire
De récentes études ont mis en évidence que les travailleurs des mines d’or du Dakota et des mines de fer du Minnesota sont exposés à des particules minérales allongées (PMA). En particulier, les mineurs du Minnesota présentent un risque plus élevé de décès par cancer du poumon, par mésothéliome et par maladies cardiaques que la population générale. Comme l’intérêt renouvelé pour l’exploration de nouveaux gisements d’or et de fer dans le Nord...
Levels and predictors of airborne and internal exposure to manganese and iron among welders
We investigated airborne and internal exposure to manganese (Mn) and iron (Fe) among welders. Personal sampling of welding fumes was carried out in 241 welders during a shift. Metals were determined by inductively coupled plasma mass spectrometry. Mn in blood (MnB) was analyzed by graphite furnace atom absorption spectrometry. Determinants of exposure levels were estimated with multiple regression models. Respirable Mn was measured with a median of 62 (inter-quartile range (IQR) 8.4–320) μg/m3 and correlated with Fe (r=0.92, 95% CI 0.90–0.94). Inhalable Mn was measured with similar...
Welders Exposed to Manganese Above Recommended Levels
Researchers investigating welding fume exposures have found that welders frequently are exposed to manganese at or above the American Conference of Governmental Industrial Hygienists (ACGIH) recommended limit of 0.2 milligrams per cubic meter.

Analysis of CTI foundry dataset
The aim of this study is to provide a statistical analysis of an exposure dataset provided by Castings Technology International (CTI). The purpose of the analysis is to provide a ‘snapshot’ of current exposure levels to ferrous foundry particulate (FFP) and other chemicals across a range of casting and fabrication related jobs. http://www.hse.gov.uk/research/rrpdf/rr677.pdf
