The US Environmental Protection Agency on March 22 released its annual air quality trends report showing continued long-term progress for all pollutants. But the report also shows that ozone and carbon monoxide problems continue to plague many major metropolitan areas. The study, National Air Quality and Emissions Trends Report, 1987, shows that during the 10-year period 1978-1987: Lead levels in the air decreased 88 percent and dropped 19 over last year. Ambient carbon monoxide levels decreased 32 percent over long term and six percent over the last year. Sulfur dioxide air quality levels dropped 35 percent over the 10 years and decreased three percent over the last year. Ambient ozone levels dropped 16 percent over the long term, but increased five percent from 1986 to 1987. Nitrogen dioxide levels decreased 12 percent over the 10 years and showed no change in the last year. Annual average particulate (dirt, dust, soot) levels dropped 21 percent over the long term, but showed a two-percent increase between 1986 and 1987.
