The large majority of the concentrations measured did not exceed the lowest levels of regulatory concern. Typically, surface concentrations exceeded subsurface concentrations at a given location. Although not the primary focus of the study, assessments of railroad track beds and asphalt surfaces as sources of polycyclic aromatic hydrocarbons were secondary purposes. Naphthalene concentrations decreased with increased distance from railroad track beds. Several polycyclic aromatic hydrocarbons decreased with increasing distance from asphalt surfaces.en-USNo known copyright.
