Not all the toxics in your car from from the tailpipe. There's a new ranking out this week that finds the worst polluters inside the car and offers some hint of how you can shop to avoid sitting in a toxic chamber when you buy a new car.

At just 1/50,000 the width of an average human hair, nanoparticles are widely used in cosmetics, medicines, and more.

But their emerging use in agriculture has raised questions about health and environmental effects, and a new report by a team of chemists at the University of Texas at El Paso concludes that those questions don't yet have answers.

After reviewing nearly 100 scientific articles on the effects of a variety of nanoparticles on edible plants (including cucumbers, rye, barley, and zucchini), the team found that both uptake and build-up of nanoparticles vary widely depending on plant type … Read more

In its latest Guide to Greener Electronics, released today, Greenpeace points to some significant changes among computer makers in keeping it clean.

Apple's ranking, for example, has dropped, from fifth place to ninth. More than a year ago, Apple was ranked the highest among computer makers, being the company that used the fewest toxic substances in making its products.

Apple's drop in the ratings, however, doesn't mean the company has been lacking in staying clean and green; but more because it didn't provide the public enough information about its future toxic chemical phase-out plans and the … Read more

Editors' note: This article was updated at 2:50 p.m. PDT with HP's statement.

It's war on hazardous chemicals that Greenpeace single-handedly provoked Tuesday.

After rating Hewlett-Packard low on its Green Meter did little to convince the company to change its ways, the organization decided to resort to trespassing.

It sent activists to HP's global headquarters in Palo Alto, Calif., where they climbed on top of the building and painted a gigantic message announcing "Hazardous Products," using nontoxic children's finger paint. The message covered more than 11,500 square feet, which is about … Read more

Struggling with the economic downturn, the biggest names in PC makers seem to lag on staying clean.

In the March issue of the Guide to Greener Electronics, released Tuesday, Greenpeace decided to knock a point off of Dell's, HP's, and Lenovo's green scores for procrastinating their commitment to eliminate toxic substances from their products by the end of 2009.

The toxic substances in question include vinyl plastic (widely known as PVC) and brominated flame retardants (BFRs). Lenovo has delayed its deadline by one year, while HP and Dell have yet to set a new timeline.

The NGO praised Apple and Acer for being the only ones firmly committed to phase out these substances. Apple has already met its commitment to have all of its products free of PVC and BFRs by the end of 2008. This is with one exception, which is a technical challenge: getting certified PVC-free power cords.

To Greenpeace, Apple is now the example for other PC makers to follow. "If Apple can find the solutions, there should be no reason why the other leading PC companies cannot," said Casey Harrell, Greenpeace International toxics campaigner. "All of them should have at least one toxic-free line of products on the market by the end of this year." … Read more

Imagine a manufacturer that took back its products after 25 years of use.

That's exactly what watchdog group Silicon Valley Toxics Coalition is recommending that the solar industry do in a white paper released on Wednesday. (Click here for PDF.)

Solar is a renewable source of energy, and solar panels don't pollute when they are generating electricity. But the upstream process of making solar panels involves a number of toxic chemicals.

Most solar cells are made out of silicon, the same material embedded in billions of electronic chips. As a result, the burgeoning solar photovoltaics (PV) industry faces … Read more

When 60 Minutes correspondent Scott Pelley and his crew went to China to record the black market dismantling of electronic waste, or e-waste, the experience was almost as hazardous for the 60 Minutes team as working with the toxic material is for poor Chinese workers.

Jumped by a gang of men overseeing the e-waste operations who tried to take the CBS team's cameras, Pelley's crew managed to escape and bring back footage of the hazardous activities. Pelley's investigation will be broadcast this Sunday, Nov. 9, at 7 p.m. ET/PT.

The Chinese attackers were trying to protect a lucrative business of mining the e-waste -- junked computers, televisions and other old electronic products -- for valuable components, including gold. "They're afraid of being found out. This is smuggling. This is illegal," says Jim Puckett, founder of the Basel Action Network, a group working to stop the dumping of toxic materials in poor countries that certifies ethical e-waste recyclers in the United States. "A lot of people are turning a blind eye here. And if somebody makes enough noise, they're afraid this is all going to dry up."

E-waste workers in Guiyu, China, where Pelley's team videotaped, put up with the dangerous conditions for the $8 a day the job pays. They use caustic chemicals and burn the plastic parts to get at the valuable components, often releasing toxins that they not only inhale, but release into the air, the ground and the water. Potable water must now be trucked into Guiyu and scientists have discovered that the city has the highest levels of cancer-causing dioxins in the world. Pregnancies in Guiyu are six times more likely to result in miscarriages, and seven out of 10 children there have too much lead in their blood. … Read more

Car interiors and car seats are becoming less toxic, although "new car smell" continues to carry poisons linked to allergies and cancer, according to a report last week by the Ecology Center.

The Ann Arbor, Mich., group found that General Motors made the most progress in reducing potentially harmful materials, followed by Mazda and Nissan, since the nonprofit's initial Healthy Car report last year.

The ingredients in question include lead, chlorine, and phthalates from plastics, as well as brominated flame retardants from cushions and padding.

The car with the best marks was the Acura RDX SH sport-utility … Read more

Most Americans live and work in buildings awash in chemicals blamed for asthma, lung cancer, and a host of other maladies.

The best way to clean the air could be with a green thumb, according to Bill Wolverton, a former NASA environmental scientist who has spent more than 30 years studying how plants purify the air. The results of his research could come to market this fall as a household air filter that looks like a potted plant.

"Every chemical we tested, plants could take them out," said Wolverton, who originally worked on life support systems for the … Read more
