Correlation of nitrogen dioxide with other traffic pollutants near a major expressway

ObjectivesThis study addresses three objectives: (1) to assess the correlation of NO2 to other ambient pollutants measured with passive samplers; (2) to explore peak traffic particulate matter air pollution correlations with passively measured NO2; and (3) to pilot an advanced mobile air pollution laboratory to supply supplementary information on correlations between NO2 and other air pollutants.MethodsActive and passive monitoring was …
