AN INVESTIGATION OF FUTURE AMBIENT DIESEL PARTICULATE LEVELS OCCURRING IN LARGE-SCALE URBAN AREAS
The Environmental Protection Agency proposed a particulate standard for diesel-powered light-duty vehicles in February, 1979, and is in the process of promulgating this standard. One of the prime inputs to this process is the effect of diesel particulate emissions on air quality. The purpose of this report is to determine the diesel's effect on ambient particulate levels over large urban areas. Past studies are examined and combined with original projections to arrive at the best estimate of ambient diesel particulate levels in U.S. cities. A companion study is being conducted to determine the diesel's impact in smaller, local areas where the impact may be significantly larger (e.g., street canyons).
