Toxic Chemicals Database Comes OnlineTuesday, May 4th, 2010
ToxRefDB captures 30 years and $2 billion of federal required testing results. This is a handy regulatory and technical tool, and simplifies at least some of the required toxicity investigation research. ToxRefDB provides detailed chemical toxicity data in an accessible format. It is a part of ACToR (Aggregated Computational Toxicology Resource), an online data warehouse that collects data from about 500 public sources on tens of thousands of environmentally relevant chemicals, including several hundred in ToxRefDB.

For over half a century, the battle against malaria has been waged with powerful anti-malarial drugs and potent mosquito-killing insecticides, weapons born from the wonders of synthetic chemistry. In recent years, however, fed up with the financial and ecological drawbacks of chemical warfare, malarious communities from China to Tanzania to Mexico have been forging a new way to fight the scourge, one that draws inspiration from the lessons of ecology more than chemistry. Rather than attempt to destroy mosquitoes and parasites outright, these new methods call for subtle manipulations of human habitats and the draining of local water bodies — from puddles to irrigation canals — where malarial mosquitoes hatch. The most striking example comes from Mexico, which has completely abandoned its previously lavish use of DDT in malaria control for insecticide-free methods and has seen malaria cases plummet. Like many countries, Mexico for decades relied upon insecticides to fight the disease, by spraying mosquito-killing chemicals on the interior walls of homes where blood-feeding mosquitoes rest, among other methods. Between 1957 and 1999, taming Mexico’s malaria required 70,000 tons of DDT. (more…) Plastic Pollution in Water Supplies to Be InvestigatedWednesday, March 31st, 2010
The federal agency, which is looking to add the chemical to its list of “chemicals of concern,” will begin measuring levels of the chemical in drinking water and ground water supplies. More than one million pounds of BPA are released into the environment annually, EPA officials say. While studies have shown that the chemical disrupts development in animals, that link has not been confirmed for humans.

Which Solar Panels Are the Greenest?Friday, March 26th, 2010
Two years since the Washington Post first reported that a maker of polysilicon for solar panels was dumping toxic waste into Chinese soil, a U.S. nonprofit has ranked the “green” aspects of 25 photovoltaic module makers. The Silicon Valley Toxics Coalition launched the Solar Scorecard (PDF) on Tuesday. Installations of solar modules rose by 42 percent in 2009, according to SolarBuzz. If this growth continues, rooftop modules that wear out within two to three decades threaten to add toxic bulk to landfills, just as yesterday’s computer monitors and cell phones have created unwieldly piles of consumer electronics waste. Where Have the Plastic Bags Gone?Tuesday, March 23rd, 2010
Plastic bags are difficult and costly to recycle and many end up on landfill sites where they take around 300 years to photo degrade. They break down into tiny toxic particles that contaminate the soil and waterways and enter the food chain when animals accidentally ingest them. But the problems surrounding waste plastic bags starts long before they photo degrade. Many become airborne and float surprising distances. Others can choke waterways and animals. The “National Post-Consumer Recycled Plastic Bags and Film Report,” conducted by Moore Recycling Associates, finds that plastic bag and film recovery increased 28 percent since 2005, driven by several factors including greater consumer access to collection programs and new markets for the recycled materials such as backyard decking, fencing, railings, shopping carts and new bags.

Terry Tamminen, who was Secretary of the California Environmental Protection Agency under Republican Governor Arnold Schwarzenegger, threw down the gauntlet last month in an editorial in which he stated that “it’s time to dump the battery-powered car in the same policy landfill as corn-based ethanol.” |
