Mohave power plant set to close

Dec 31 ,Space & Earth science


A coal-fired power plant that emitted vast quantities of air pollution that clouded views of the Grand Canyon will close at year's end.

The utility has confirmed a U.S. court ordered Mohave Generating Station near Laughlin, Nev., to shut down unless it upgraded its pollution controls by Jan. 1, reported the Los Angeles Times Friday.

Environmental groups had sued in 1999, alleging the plant repeatedly violated the Clean Air Act.

The 1,580-megawatt Mohave plant, which provided 7 percent of electricity to Southern California Edison, released an average of 19,000 tons of nitrogen oxide, 40,000 tons of sulfur dioxide and 2,000 tons of fine particles a year near Laughlin. That smog and soot pollution has contributed to the haze above Grand Canyon.

In a filing Thursday with the California Public Utilities Commission, Edison said it wanted to continue negotiations to keep the power plant open, to add pollution controls that are expected to cost $1 billion, but close for at least a few months.

Probing Question: How do antioxidants work?
Blueberries, pomegranates, green tea and dark chocolate -- these are just some of the antioxidant-rich "superfoods" found in almost any supermarket today. As well as improving our general health, there is growing evidence that diets high in antioxidants may confer some protection against a long list of chronic diseases, including Alzheimer's disease, cancer and even HIV. Given their increasing popularity, the fundamental question bears asking: What exactly are antioxidants, and how do they work in our bodies?

Closing coal-burning power plant in China and improved cognitive development in children
Closing coal-fired power plants can have a direct, positive impact on children's cognitive development and health according to a study released by the Columbia Center for Children's Environmental Health (CCCEH) at Columbia University's Mailman School of Public Health. The study allowed researchers to track and compare the development of two groups of children born in Tongliang, a city in China's Chongqing Municipality – one in utero while a coal-fired power plant was operating in the city and one in utero after the Chinese government had closed the plant. Among the first group of children, prenatal exposure to coal-burning emissions was associated with significantly lower average developmental scores and reduced motor development at age two. In the second unexposed group, these adverse effects were no longer observed; and the frequency of delayed motor developmental was significantly reduced. The study findings are published in the July 14th Environmental Health Perspectives.
