Worker Health Study Summaries - Asphalt Pavers NIOSH

The study was about the potential health effects of exposure to PAHs in paving asphalt. PAHs are polycyclic aromatic hydrocarbons. Some PAHs have been shown to cause cancer. Some workers in the NIOSH study were exposed to regular asphalt and CRM (crumb rubber-modified) asphalt fumes during their workday and some workers were not.
