• Description:
  The literature on worker exposure is limited but growing in size and pertinence. Initially, the focus of research was on exposures to workers handling raw, as-manufactured nanomaterials in laboratories and small production facilities. Research in Europe and the United States has more recently been focused on potential exposures to workers handling products after the nanomaterials are incorporated into matrices such as polymers, coatings, and cementitious products. A major review of 54 studies on release of nanomaterials from solid nanocomposites along the life cycle from drilling and sanding to eventual shredding, incineration, and composting provided a broad foundation for this workshop session. There are several methods for measuring releases from nanocomposites. For carbon nanotubes (CNTs) and carbon nanofibers (CNFs), new NIOSH findings from a range of workplaces add important exposure data. There is an innovative thermophoretic personal sampler for collecting airborne nanoparticles on a grid for direct analysis by transmission electron microscopy. The technology promises to reduce the number of overloaded filters during sampling, which has meant voided samples in the past. [Description provided by NIOSH]
