| Abstract |
Trends in ambient levels of oxidants over periods of five years or more are reviewed for seven locations in the United States. Statistically significant downward trends were identified in the San Francisco Bay Area and in Denver. Trends in emissions of organic and NOx precursors over comparable periods are also reviewed. Only in San Francisco were the data sufficient to note a statistically significant relationship between precursor emission trends and the trend in ambient oxidant. Downward oxidant trends are most pronounced in the western part of the Bay area. Indications are that a five year period may not be sufficient to identify statistically significant trends in many areas. Downward trends in the Bay Area are much more pronounced when 13 years of records are examined. |
