Image: Sampling Dust From Sealcoated Pavement

Detailed Description

USGS researchers collect samples of dust from a sealcoated parking lot for analysis of polycyclic aromatic hydrocarbons (PAHs).  PAH concentrations in dust swept from coal-tar-sealcoated parking lots are 100s to 1000s of times higher than those swept from parking lots with other types of surfaces.
