• Description:
  Humans have known about the antibacterial properties of silver since ancient Greece. Today, manufacturers of construction products are using silver nanoparticles (AgNPs) to enhance an increasing number of materials, including lumber, flooring products, paints, and coatings. However, exposure to AgNPs may pose a health risk, and previous research has not evaluated this exposure risk among construction workers. The National Institute for Occupational Safety & Health (NIOSH) recently evaluated over 100 studies of silver nanomaterial toxicity and derived a recommended exposure limit (REL) of 0.9 µg/m3 as an airborne respirable 8-hour time-weighted average concentration. For this study, CPWR researchers took air samples while a tradesperson sprayed two types of paint. One was a conventional paint, the other a biocidal paint containing AgNPs to prevent growth of bacteria, mold, and mildew, common hazards for building occupants and workers. This study included comparisons to exposure limits like the NIOSH REL and focused on better understanding exposure risks to workers who spray paints containing AgNPs.
