DATA FOR 10 YEARS SHOW REMARKABLE IMPROVEMENT IN U.S. AIR QUALITY

The U.S. Environmental Protection Agency (EPA) recently reported the air quality trends for six pollutants for which it has issued National Ambient Air Quality Standards (Naaqs). The analyses are based on data from some 4,000 air pollution monitors throughout the U.S. The 1993 data disclose changes for the 1984-1993 period and indicate significant improvements in the concentrations of all pollutants tested: (1) Ground-level ozone decreased 12 percent; (2) Lead decreased 89 percent; (3) Sulfur dioxide (SO2) dropped 26 percent; (4) Carbon monoxide (CO) declined 37 percent; (5) Nitrogen dioxide (NO2) levels fell 12 percent; (6) Particulate matter smaller than 10u (PM-10) has decreased 20 percent since 1988.
