The Toxicity Of Wildfire Smoke

The health threat to city dwellers posed by Southern California wildfires like those of November 2008 may have been underestimated by officials. Detailed particulate analysis of the smoke produced by previous California wild fires indicates that the composition posed more serious potential threats to health than is generally realized, according to a new paper analyzing particulate matter (PM) from wildfires in Southern California.

Freshwater Pollution Costs US At Least $4.3 Billion A Year

Pollution by phosphorous and nitrogen isn't just bad for lakes, streams and other bodies of fresh water. According to researchers at Kansas State University, it's also bad for Americans' pocketbooks. Freshwater pollution impacts individuals on a level as basic as how much they spend on bottled water, said Walter Dodds, professor of biology at K-State. If you worry about what's in the tap water, you might be shelling out more money for the bottled variety, he said.

Coordinated Response To Economic And Environmental Crises Urged At Top Scientific Meeting

A fix for the economy must address ecological threats, a top international scientific meeting here has urged. Human society is moving dangerously beyond the planet's natural limits in a striking parallel to the financial debt crisis. "We're running the planet like a subprime loan," Dr. Johan Rockström of the Stockholm Resilience Centre said. A coordinated response would reduce the risks of both kinds of crises in the future.

Revised Theory Suggests Carbon Dioxide Levels Already In Danger Zone, Study Published In Open Atmospheric Science Journal

If climate disasters are to be averted, atmospheric carbon dioxide (CO2) must be reduced below the levels that already exist today, according to a study published in Open Atmospheric Science Journal by a group of 10 scientists from the United States, the United Kingdom and France.

Cleaning Heavily Polluted Water At A Fraction Of The Cost

Eureka project E!2962 Euroenviron Biosorb-Tox has succeeded in developing a water treatment system for industrial oil polluted water at a tenth of the cost of other commercially available tertiary treatments, leaving water so clean it can be pumped safely back out to sea without endangering flora or fauna. Wastewater from ships, oil refineries and other petrochemical industries is heavily contaminated with toxic compounds.

When Electricity Prices Rise, Electricity Use Significantly Reduced By Households

A new study in the RAND Journal of Economics examined how quickly households change their electricity use when prices rise and fall rapidly. Results show that when electricity prices increase, the average household rapidly reduces its electricity use. However, when electricity prices then decrease, household energy use returns to previous levels. Matthew White and Peter C.
