  • Using the Aerasense NanoTracer for simultaneously obtaining several ultrafine particle exposure metrics

    Abstract. The expanding production and use of nanomaterials increases the chance of human exposure to engineered nanoparticles (NP), also referred to as ultrafine particles (UFP; ≤ 100 – 300 nm). This is particularly true in workplaces where they can become airborne and thereafter inhaled by workers during nanopowder processing. Considering the suspected hazard of many engineered UFPs, ...

  • Silver Membranes in Monitoring Respirable Crystalline Silica

    Crystalline silica, most commonly found in the form of quartz, is a basic component of the earth; it’s found in soil, sand granite, and other minerals. During many industrial processes, crystalline silica is released as particles that are 100 times smaller than beach sand.1 Due to their size, these mineral particles cannot easily be cleared by human lungs. Instead, they persist in the ...
