"A new government study adds to the evidence that thimerosal, a mercury-based preservative until recently found in many vaccines, does not increase children's risk of autism."

"U.S. Department of Agriculture experts found growing sanitary problems including bugs and overflowing trash earlier this year on the Iowa farm at the center of the national egg recall, but didn't notify health authorities, according to government documents and officials."

"The Environmental Protection Agency sent letters to nine drilling companies on Thursday requesting detailed information about the chemicals contained in fluids used to crack open underground rock formations in the hunt for oil and natural gas."

"In the rush to develop America's biggest new source of domestic energy, one community is fighting to protect its rural way of life from the environmental strains that accompany shale gas drilling."

"Hundreds of people packed a public hearing Wednesday in Dallas to sound off on a federal proposal to label the ash from coal-burning power plants a hazardous waste."
 

Three environmental groups have issued a report detailing some 39 cases across the U.S. where pollution from the ash left from coal-burning electric power plants has cause pollution that often threatens human health. Now as EPA moves to close the electric utilities' longtime exemption from hazardous waste laws, industry lobbyists may have quietly put the fix in at the White House Office of Management and Budget.

"The United States ended its involvement in the Vietnam War 35 years ago, and established diplomatic relations with Hanoi 15 years ago.  But a recent visit to Vietnam by members of the U.S.-Vietnam Dialogue Group on Agent Orange and Dioxin saw the lingering effects of highly toxic chemicals used by U.S. forces to remove dense vegetation in a bid to flush out enemy combatants."

In a classic two-sided story, the New York Times reports scientific uncertainty about whether the ubiquitous plastic chemical BPA hurts humans or not. It does not explore another key question: should the burden of proof be on companies to prove chemicals they widely expose people to are safe? -- or on environmental health scientists to prove them unsafe?

The application of sewage sludge (renamed "biosolids" by industry PR) to fields has created worries about smell, disease, and toxic contaminants. Federal efforts to track sludge problems have been fragmented, haphazard, and delayed -- which does not inspire confidence in industry-backed federal assurances that sludge is safe. The assurances have preceded the evidence that would support them.
