摘 要：In the Eastern Seaboard Intermodal Transportation Applications Center at Hampton University, we started an investigation of the air pollutants around heavily-travelled roadways, shipping channels, airports, and railroads with the purpose of obtaining real time measurements of pollutant concentrations and relating them to real-time weather and traffic information. In the first two cycles of our research program, we built a mobile unit containing a NOx and an ozone analyzer, and a weather station to provide simultaneous measurements of wind speed, wind direction, temperature, and solar intensity with the concentration measurements. The measured NO2 concentrations were compared to the predictions of CALINE4. Considering the effects of PM2.5 on public health and the 2008 US Census Bureau report, which showed that around 16% of American households live within 100 m of a highway having four or more lanes, an instrument for the measurements of PM10 and PM2.5 were added to our measurement capabilities for the current research cycle.
