And though it does not break new scientific ground, it provides evidence from recent research that acid precipitation is more complex and more intractable than had been thought 10 years ago.

To combat the problem, Sen . Daniel Patrick Moynihan, D-N . Y ., has proposed legislation that would reduce the airborne pollutants _ sulfur and nitrogen _ that cause acid precipitation.
23.
Acid precipitation occurs when sulfur or nitrogen, which drift eastward on the prevailing winds, mix with moisture in the atmosphere to form sulfuric or nitric acid and fall as acid rain, snow or fog.

The observed effects on soil chemistry were unexpected, Likens said, and neither those effects nor other other data based on long-term observations were reflected in the 10-year federal study, the National Acid Precipitation Assessment Program.
25.
They cite the work by the National Acid Precipitation Assessment Project, a 10-year study that was published in 1990 and says that the problem of acid rain was exaggerated when it first came to prominence.
26.
In a letter to Albright, Eliot Spitzer said nitrogen oxide and sulfur dioxide emissions from Eastern Canada's aging power plants " are among the leading contributors to acid precipitation " in New York and the Northeast.
27.
The resulting increase in cloud reflectivity ( or albedo ) would reflect more incoming light from the sun than usual, and cool the entire planet until the suspended sulfur fell to the ground as acid precipitation.
28.
For years, scientists have viewed the Adirondack Mountains in New York, where hundreds of lakes and streams can no longer sustain life because of chronically high acidity, as the region that suffers the most from acid precipitation.
29.
The report, a comprehensive survey of recent research, concludes that despite important strides in reducing air pollution, acid precipitation remains a serious problem in the Adirondacks and is a growing threat in the southern Appalachians, Colorado's Front Range and elsewhere.

He was also at various times vice president for research and development at Weyerhaeuser Company, director of research of the National Acid Precipitation Assessment Program, affiliate professor at the University of Washington, a consultant in environmental and energy affairs, and owner of Teledyne Isotopes.
