Check out the New York Times for a rundown of the impressive environmental initiatives the nation's largest retailer is undertaking. Wal-Mart plans to double fuel economy on its delivery trucks, reduce energy use in its stores and minimize packaging.

In the past week, activists have pressed Teflon maker DuPont to clean up its act on two fronts. Environmental groups demanded that the company monitor groundwater around its local plant, the only one in the US that makes this indestructible, cancer-causing chemical, and the steeworkers' union urged carpet and clothing retailers and fast food companies to warn consumers that their products may be coated with chemicals that break down into DuPont's toxic Teflon chemical.

As the Detroit News reports, Ford Motor Co. has again withheld evidence of safety problems with its SUVs and other vehicles. For Ford, it’s hardly an isolated incident.

A new study presented at a meeting of the Society of Environmental Toxicologists and Chemists links the Teflon chemical C8 [also known as PFOA] to elevated cancer rates. Researchers found higher levels of prostate cancer in men and cervical and uterine cancer in women exposed to C8 than in the general population.

PFOA is used to make PTFE, the Teflon in pans. However, scientific evidence points to fluorotelomers as the main source of the PFOA and other perfluorinated chemicals in Americans' blood. That fluorotelomers on coated paper food packaging break down into PFOA and other chemicals is a separate problem from PTFE and cookware. This source of PFOA is one that DuPont cannot control by reducing emissions or impurities in its products.

EWG asks the CEOs of nine major fast food corporations to disclose the use of toxic nonstick chemicals in their packaging.

Telfon-coated cookware poses a hazard when it is heated to high temperatures. EWG tests show that in 2 to 5 minutes on a conventional stovetop, cookware coated with Teflon and other non-stick surfaces can exceed temperatures at which the coating breaks apart and emits toxic particles and gases linked to hundreds, perhaps thousands, of pet bird deaths and an unknown number of human illnesses each year.

The Environmental Working Group today asked the Consumer Product Safety Commission (CPSC) to ban the use of arsenic-treated wood in outdoor play structures and to order consumer refunds for millions of playsets nationwide, based on a new round of laboratory tests that found high levels of arsenic contamination even on older pressure-treated wooden structures.

Ford has been the subject of some strong charges by our organization about its veracity with customers and the public about the safety of its Bronco II-Explorer model line.
