A fundamental examination of air pollution by roadway dust (Part 1) A research of indicator elements by multielement analysis

摘要

Non-destructive neutron activation analysis was applied to a research of indicator elements in asphalt, diesel and gasoline engine soot, tire tread, tire stud and road beacon paint that were considered to be structure materials of roadway dust. From the analysis of 38 elements, suitable indicator elements were found, i.e. bromine in gasloline engine soot, tungsten in tire stud tip and chromium in yellow paint but no suitable indicator elements was found in asphalt, tire tread and diesel engine soot.
