Traditional gravimetric based methods for exposure assessment may not effectively characterize the respiratory insult experienced by miners due to exposed small particles. An on-site evaluation of particle emissions from the feed-leg drilling activity was conducted to characterize particle size and elemental composition. Air quality was monitored using direct reading instruments for sizes of 10nm to 10mm and particles were collected using a novel nanoparticle sampler side by side with a respirable cyclone sampler. This webinar presents the need for nanoparticle exposure assessment in a mining workplace.
