How to avoid the enviro nasties that lurk in pools
Let water sit around for 24 hours — stagnating in an old tire, say, or in a birdbath in the backyard — and some pretty nasty things can start breeding in it. After Mt. St. Helen’s erupted in Washington State in 1980, newly formed oxygen-deprived pools became breeding grounds for Legionnaires’ disease. Then there’s cholera, […]

Michelle Nijhuis reviews Libby, Montana by Andrea Peacock
It's never been easy to make a living in Libby, Mont. Citizens in this town of 12,000, tucked into the dense, damp conifer forests of northwestern Montana, have long scraped by on seasonal logging jobs and other sporadic work. So in the 1920s, when local entrepreneur Edward Alley discovered that a nearby vermiculite deposit yielded an efficient, lightweight insulation and fireproofing material, Libbyites were thrilled.

Weed Between the Lines
In a finding that undermines one key argument in favor of genetically modified (GM) crops, researchers at Iowa State University have discovered that a number of “superweeds” have developed a resistance to Monsanto’s widely used Roundup herbicide.

The Farmer and the Smell
The U.S. EPA could offer large industrial livestock farms amnesty from the federal Clean Air Act and Superfund laws, according to people involved in agency-industry talks. Rather than enforce the laws, the EPA would monitor pollution levels at roughly 30 large hog and chicken operations, a plan environmentalists and former enforcement officials say is far […]

Giving the Devil His DU
As many people wonder about the long-term environmental effects of the war in Iraq, the U.N. has issued a report documenting the ongoing pollution problems posed by depleted uranium (DU) ammunition used by NATO forces in Bosnia-Herzegovina in the mid-1990s. The report, published by the U.N. Environment Programme, found DU contamination in groundwater and drinking […]

What we don’t know about the toxic chemicals in our bodies
Scientists call the accumulation of chemical contaminants (such as PCBs, mercury, and pesticides) within a person’s body the “body burden.” Body burden is just a number, a concentration in parts per billion or micrograms per liter. But the term calls forth an image, too, of a body bent over and struggling beneath a heavy load. […]
