Every cell in the body continually carries out millions of biochemical processes requiring oxygen. By-products of this cellular metabolic process are unstable electrons called oxidants or “free radicals.” Unfortunately, these free radicals are not harmless. Their chief danger comes from the damage they incur upon cellular structures or DNA. Anti-oxidants reduce the effects of dangerous oxidants by binding with them, thereby decreasing their destructive power. Food sources of antioxidants include those with high vitamin A, C, E and beta-carotene contents, such as spinach and liver. Anti-oxidants are thought to have a role in slowing the aging process, preventing heart disease and protecting against the development of cancers.

Local officials must reduce smog by June 2009, the Environmental Protection Agency said Thursday after increased testing found unacceptable air quality in parts of Maricopa and Pinal counties.

Tougher smog standards roll out nationwide today.

It's a green home-building feature particularly fitting for Southern California: a concrete tile roof that neutralizes the smog-forming nitrogen oxides spewed by automobiles.

The Arizona Department of Environmental Quality has issued an ozone high-pollution advisory for Friday.

Arizona State University has received a $14 million, five-year grant from the U.S. Department of Energy to establish an Energy Frontier Research Center, which will study ways of using solar energy to convert water into oxygen and hydrogen fuel.

I was happy to see electric cars being talked about in the Tribune story "Charged up for electric cars." It stated that the Valley and Tucson will be installing about 900 residential charging stations and the forthcoming mass hook-up of 1,150 chargers in the spring. I am completely for becoming environmentally friendly, but I know at least three other families that can't afford the price tag of $25,280 after federal tax credits for a car that only takes you 100 miles and takes 2 1/2 hours to become fully charged. Electricity comes from coal-burning power plants that make up 54 percent of America's power, but it emits toxic chemicals into the air like mercury, arsenic, nitrogen oxide, sulfur oxide and many more.

FLAGSTAFF — The U.S. Environmental Protection Agency has imposed new pollution limits on three coal-fired Arizona power plants, aiming to protect the environment and air quality for wilderness areas and landmarks such as the Grand Canyon.

Every cell of the body continuously carries out biochemical processes that require oxygen. The overall term for this on-going process is metabolism. By-products of this cellular metabolic process are unstable electrons called oxidants or “free radicals.” Unfortunately, these free radicals are not harmless. Their chief danger comes from the damage they incur upon internal cellular structures such as DNA.

Just in time for Earth Day observance, a study published in last week’s Environmental Research Letters warns that animal manure and fertilizers used in growing animal feed emit large amounts of nitrous oxide, a powerful greenhouse gas. An op-ed piece in this week’s New York Times warns that the devastating environmental impacts of a meat-based diet are actually magnified when raising animals on the range, because this involves much more land and more greenhouse gas emissions.

The Valley will be under an ozone high pollution advisory Thursday.

The Arizona Department of Environmental Quality has extended Monday’s ozone health watch into Tuesday.

Gilbert police are looking for three men involved in the shooting death of a Chandler man near Cooper and Warner roads Tuesday night.

HONG KONG - Thailand's military coup this week interrupted filming of Nicolas Cage's new movie, a gangster thriller being shot in Bangkok, a news report said Thursday.
