Black Carbon along a Highway and in a Residential Neighborhood during Rush-Hour Traffic in a Cold Climate
Short-term exposure to ultra-fine Black Carbon (BC) particles produced during incomplete fuel combustion of wood and fossil fuel has been linked to respiratory and cardiovascular diseases, hospitalizations and premature deaths. The goal of this research was to assess traffic-related BC in a cold cli...
