Effects of oxides of nitrogen on California air quality. Final report

Technical Report · Sat Mar 01 04:00:00 EST 1986

OSTI ID:6503906

The report was written because of California Air Resources Board concerns about the multiple effects of oxides of nitrogen (NOx) emissions on California air quality. The deleterious effects are expected to increase because NOx emissions are expected to increase in 1990's. The report discusses six major products of nitrogen oxide (NOx) emissions: nitrogen dioxide, ozone, particulate nitrates, acid deposition, visibility impairment, other nitrogen compounds. For each product, the report describes health and welfare effects, atmospheric chemistry by which NOx emissions are transformed into various air pollutants, relevant ambient air quality standards, ambient concentrations measured in California, and status in attaining ambient air standards. Because ozone is California's most severe air pollution problem, the report discusses in depth the relationship of NOx and ozone. In most areas of California, ozone strategies have reduced hydrocarbon emissions while maintaining NOx emissions. Evidence is increasing that reduction of NOx emissions also reduces ozone.
