Air samples were collected by personal sampling with five stage Sioutas cascade impactors and respirable cyclones in parallel among tappers and crane operators in two manganese (Mn) alloy smelters in Norway to investigate PM fractions. The mass concentrations of PM collected by using the impactors and the respirable cyclones were critically evaluated by comparing the results of the parallel measurements. The geometric mean (GM) mass concentrations of the respirable fraction and the <10 μm PM… 
Challenge with a Personal Cascade Impactor Sampler in a Silicon Metal Smelter
ABSTRACT Cascade impactors are useful tools in the measurement of particle size mass distribution of workplace aerosols. The application of cascade impactors, however, is sometimes challenging.
Evaluation of Sub-micrometer-Sized Particles Generated from a Diesel Locomotive and Jackleg Drilling in an Underground Metal Mine.
TLDR
The mass concentration to which workers are potentially exposed was determined from a 4-h sampling in the vicinity of drilling activities in an underground metal mine; this concentration was found to be lower than 0.6 mg m-3 of total respirable dust.
Reactive hyperemia and baseline pulse amplitude among smelter workers exposed to fine and ultrafine particles
TLDR
PM exposure was associated with higher BPA among participants older than 34 years and older, and this results may indicate an age-dependent cardiovascular susceptibility to PM exposure.
Airborne Emissions from Mn Ferroalloy Production
Airborne emissions from metal production represent a health, safety, and environmental challenge to which more and more attention is being directed. Industries worldwide, as well as authorities and
The Effect of a Knowledge-Based Intervention on the Use of Respirators in the Norwegian Smelter Industry
TLDR
The results indicate that interventions can increase workers’ knowledge and attitudes, and reduce perceived inconvenience regarding the use of respiratory protective equipment, however, reported respirator use did not improve for either groups participating in the study.

Manganese air exposure assessment and biological monitoring in the manganese alloy production industry.
TLDR
A novel four-step chemical fractionation procedure developed for the speciation of Mn in workroom aerosols was applied for selected aerosol filters and no significant association was found between the "insoluble" components (probably SiMn) and Mn in biological samples.
Beryllium Aerosol Characteristics in the Magnesium and Aluminum Transformation Industry in Quebec: A Comparison of Four Different Sampling Methodologies
TLDR
Inhalable aerosol measurements should remain the tool for estimating the risk of exposure to beryllium in foundries and smelters in these settings until a clear dose response is established for these sampling heads.

Particulate matter emissions near active copper smelters and mine tailings in the southwestern United States pose a potential threat to nearby environments owing to toxic species that can be inhaled
Particle size and chemical species 'fingerprinting' of aerosols in primary nickel production industry workplaces.
TLDR
It was shown that, for practical purposes, the distributions of the four nickel species groups were consistently uniform across the full range of particle-size distribution, which enabled incorporation of additional data taken at those same sites using the IOM personal inhalable aerosol sampler to permit the development of exposure 'fingerprints' for each worksite.
Physicochemical characterisation of different welding aerosols
TLDR
Physicochemical properties important in exposure characterisation of four different welding aerosols were investigated and a clear size dependence of the particle chemical composition was encountered in the case of manual metal arc welding aerosol.

TLDR
A comparison of data collected using impactors and cyclones demonstrated that cyclones could be used to differentiate larger aerosol particles from fumes, rather than requiring the use of impactors.
Novel active personal nanoparticle sampler for the exposure assessment of nanoparticles in workplaces.
TLDR
Both NPs and RPM concentrations were found to agree well with those of the IOSH respirable cyclone and MOUDI and can be further analyzed for chemical species concentrations besides gravimetric analysis to determine the actual exposure concentrations of ENMs in both RPM and NPs fractions in workplaces.
Hygroscopic properties of the workroom aerosol in aluminium smelter potrooms: a case for transport of HF and SO2 into the lower airways.
TLDR
Results indicate that at least HF may penetrate deeper into the lung in the presence of soluble particles or particles that form surface water films compared to HF alone.
Characterisation of workplace aerosols in the manganese alloy production industry by electron microscopy
TLDR
The pronounced differences in particle composition along the production line clearly show that workers are exposed to a variety of Mn-containing species, and MnO particles have a higher solubility than MnSi particles and are thus more bioaccessible, suggesting a higher risk of adverse health effects in the FeMn production than in the SiMnProduction.
