Levels of polycyclic aromatic hydrocarbons in Canadian mountain air and soil are controlled by proximity to roads
Concentrations of polycyclic aromatic hydrocarbons (PAHs) were measured in soil and XAD-based passive air samples taken from a total of 22 sites along three transects (Revelstoke, Yoho, and Observation, 6-8 sites for each transect) in the mountains of Western Canada in 2003-2004. Median concentratio...
