Estimated Monthly Emissions of Sulfur Dioxide, Oxides of Nitrogen, and Volatile Organic Compounds for the 48 Contiguous States, 1985-86: Volume 1, Interim Update and Methodology Review.

摘要

The purpose of this report is threefold. First, it reports recent trends in sulfur dioxide (SO(sub 2)) and oxides of nitrogen (NO(sub x)) emissions. This work is part of a continuing study of the seasonal and regional patterns of these pollutants. An earlier Argonne National Laboratory (ANL) report, estimated Monthly Emissions of Sulfur Dioxide and Oxides of Nitrogen for the 48 Contiguous States, 1975-1984, presented estimates of NO(sub x) and SO sub 2 emissions that were developed for each month by state. This report extends the NO(sub x) and SO(sub 2) series to 1985 and 1986. In addition, emission estimates are introduced for a new class of pollutants, volatile organic compounds (VOCs). The VOC estimates are given for 1985 and 1986 by month and state. Second, this report discusses how the estimating methodology used in this update differs from that used in the previous report. Third, this report examines areas in which the methodology could be improved. Changes in the methodology and improvements in the data sources could result in more accurate and efficient estimates of pollution emissions. 20 refs., 13 figs., 2 tabs. (ERA citation 13:041157)
