• Abstract:
  Recent research has identified the public health importance of air pollution exposures ; near busy roadways. As a result, EPA significantly revised its NO2 air quality standard in 2010. ; The current regulatory focus has shifted from assessment of longer-term (annual average) NO2 ; concentrations measured at locations away from busy roads to shorter-term (1-hour average) ; concentrations measured at locations near busy roads. Given the potential importance of ; understanding both near-road and on-road NO2 exposures in built-up urban areas, additional ; monitoring approaches are needed that are relatively user-friendly, specific to NO2 rather than ; general oxides of nitrogen, and sufficiently flexible to be deployed at both near-road locations ; over time as well as on busy freeways over both time and space.
