The toxicity of nanoparticles has received increased attention in the recent years. Toxicologists proposed to determine the total airborne nanoparticle surface area as a health relevant measure in order to assess worker exposure. If there is a leak in nanoparticle production equipment, nanoparticles can be emitted in large quantities. Between the leak and the point of human exposure they undergo physical or chemical reactions that can change the particle properties, including number and surface area concentrations, morphology, or chemical composition. In this project the PI proposes to measure the fate of nanoparticles, emitted through a leak in a nanoparticle production process into a workplace environment. Dr. Pui will particularly focus on changes of the nanoparticle surface area.
