The project’s long-term aim is to prevent and assess nanoparticle (NP) exposures in Canadian workplaces by determining the role of metal-based NPs on lung function and the exacerbation of pre-existing respiratory diseases. The researchers intend to examine the toxic effects of these nanoparticles on a novel artificial lung chamber, which the researchers say is a more authentic replication of the inhalation of NPs. The researchers will conduct this study using a workplace focus, i.e. attempting to replicate the NPs released into the air during welding and shipbuilding.
