Alfred E Neuman is a better choice than Bush........at least he has character, Bush has none. Everything in life is not dollar and cents .........sometimes you have to put people's wellbeing first. Philanthropy and humanitarianism go hand in hand to improve our lot unlike greed and avarice which denegrate our existence.

Catalytic Converters May Cause Pollution
By Nancy A. Melville
HealthSCOUT Reporter

SATURDAY, Sept. 30 (HealthSCOUT) -- The same devices credited with clearing up vehicle air pollution around the world may in fact be polluting the atmosphere.

Researchers at the University of California, (UC) Berkeley, say that catalytic converters -- considered so essential in reducing auto emissions -- appear to produce large quantities of ammonia, which can result in the heavy layers of brownish haze that blanket many urban areas.

The findings are based on a sampling of emissions from more than 60,000 vehicles in a California highway tunnel over eight days.

The samplings showed that while cars equipped with modern catalytic converters emit about 50 percent less hydrocarbons, carbon monoxide and other harmful gases than cars in earlier studies, the typical vehicle emitted 0.28 ounces of ammonia -- the equivalent of a teaspoon -- per hundred miles. Findings appear in the Sept. 1 issue of Environmental Science & Technology.

The amount of ammonia emitted from the cars is much less than the other pollutants, but it's not an insignificant amount, says lead researcher Robert Harley, an assistant professor at UC Berkeley.

"The ammonia emissions are about 27 percent of things like nitric oxide, so it is a significant amount of ammonia," he says.

Besides addinig to atomospheric haze, Harley says ammonia is the source of health concerns.
