Characterization and control of occupational exposure to nanoparticles


Very little is known about levels of exposure to ultrafine particles and nanoparticles in workplaces. The aim of this project is to estimate the concentration of ultrafine particles in aluminum smelter workers, apprentice welders and nanoparticle producers. It will study the variables determining exposure, the effect that their modification may have on the concentrations, and the possibility that these determining variables can act directly on exposure, based on the size distribution of the particles. By characterizing still unexplored exposures and by determining potential variables that can be modified, workers’ exposure can be evaluated in an emerging technological field. This will then allow better control of particle emissions and thus reduce the risks to which the workers are exposed.
