Abstract |
The report presents the results of intensive air pollution sampling covering seven days, including one weekend, and one all-night sampling period. The period covered was December 2 through December 8, 1960, from 9:00 AM, to 5:00 PM. The all-night sampling period covered 9:00 AM, December 5 through 9:00 AM, December 6. The gas and particulate pollutants under test were selected to be indicative of the general air pollution of the area. Visibility measurements to ground level objects were taken every hour. The roof of the seven-story District of Columbia Municipal Center Building, 300 Indiana Avenue, N. W., was selected as the sampling site. (Author) |
