• Description:
  Objective: The primary objective of this study was to assess NO2 and O3 personal exposure levels of youth in an urban environment and to assess whether ambient air concentration data collected by the U.S EPA at the nearest fixed site air monitoring stations are representative of personal exposure concentration measurements. Methods: Thirty-six African American and Hispanic youth at two different environmental camps operated by the city of Chicago Park District (CPD) were recruited for this personal exposure assessment study. Both personal and area samples were obtained using passive NO2 and O3 badges. A fixed-site air monitoring station was established at each park to measure area NO2 and O3 ambient air concentrations. The air monitoring data collected at the nearest urban station for the study time frame was obtained from USEPA's AIRS database. Time-activity data of participants were recorded in five-minute intervals. Statistical methods were employed to analyze the personal and area exposure concentration data along with USEPA fixed-site air monitoring data for NO2 and O3. Results: Week 1 and 2, NO2 and O3 average weekly personal concentrations (AWPC) were below the EPA NAAQS. For Week 3, while 65% of NO2 measurements were above NAAQS, all O3 measurements were below NAAQS. For Week 4, 31% NO2 and 13% O3 measurements were above NAAQS. For Week 5 and 6, 22% and 37% of NO2 measurements were above NAAQS, respectively. However, O3 measurements were all below NAAQS for Week 5 and 6. Conclusions: Current NO2 NAAQS may not be effectively protecting underserve populations within urban areas as indicated by, personal NO2 measurements obtained for Weeks 3, 4, 5 and 6.
