OSTI ID:7248483
A series of field measurements was carried out in six U.S. cities to assess the magnitude and variability of the concentration of 29 potentially toxic air pollutants. The measurements were conducted on a 24-hour-per-day basis for periods of 1 to 3 weeks in each the following cities: Philadelphia, PA; Staten Island, NY; Downey (Los Angeles), CA; Houston, TX; Denver, CO; and San Jose, CA. The chemicals measured included chlorofluorocarbons, halomethanes, haloethanes, halopropanes, chlorinated alkenes, aromatic hydrocarbons, organic nitrogen compounds, and aldehydes. For most species, average concentration were less than 5 parts per billion (v/v). The data were analyzed and compared with historic data in order to examine for trends.
