PPT-Particle Composition and Respirable Crystalline Silica Concentrations in Sand Mining and

Joe Oster Junyi Zhang Callie Fischer Mentor Dr Patricia Cleary Department of Chemistry UWEau Claire A Sioutas Personal Cascade Impactor was loaded with four 25mm 20μm PTFE filters to collect the airborne particles from the sand mining facility The four sampling filters and one field blank filter the same type as the sampling filters were weighed before and after sampling to the nearest 001mg a minimum of three times until a variability of less than 01 was attained This allows for the determination of how much particle mass was collected on the filters over the 24 hour sampling period.
