I think plastics as a byproduct in the refinement of oil is a product that will keep ruining our planet, and I am convinced that there are no "safe plastics".
Even the so called bio degradable plastic is crap for nature, thanks DuPont.
Our enormously productive economy ... demands that we make consumption our way of life, that we convert the buying and use of goods into rituals, that we seek our spiritual satisfaction, our ego satisfaction in consumption ... we need things consumed, burned up, replaced and discarded at an ever-accelerating rate.

and now with this, nano technology? makes my skin crawl because it easy gets under your skin.
So this topic doesn't surprise me at all to be honest, good work OP.
The toxicity associated with PCBs and other chlorinated hydrocarbons, including polychlorinated naphthalenes was recognized very early due to a variety of industrial incidents.[8] A conference about the hazards was organized at Harvard School of Public Health in 1937, and a number of publications referring to the toxicity of various chlorinated hydrocarbons were published before 1940.[9] Robert Brown reminded chemists in 1947 that Arochlors were "objectionably toxic. Thus the maximum permissible concentration for an 8-hr. day is 1 mg/m3 of air. They also produce a serious and disfiguring dermatitis".[10] However, PCB manufacture and use continued with few restraints until the 1970s.
Pittsfield is one of GE’s hometowns. Pittsfield was home to GE’s transformer and capacitor divisions, and electrical generating equipment built and repaired in Pittsfield powered the electrical utility grid throughout the nation.
PCB-contaminated oil routinely migrated from GE’s 250-acre industrial plant located in the very center of the city to the surrounding groundwater, nearby Silver Lake, and to the Housatonic River, which flows through Massachusetts to Connecticut on down to the Long Island Sound. Faced with ever mounting amounts of PCB-contaminated material, and with a growing need to dispose of this material, GE and its contractors hauled and dumped PCB-contaminated material anywhere they could. They still had too much. So GE in the 1940s and 50s launched a giveaway program. GE employees and their neighbors and local contractors, in return for signing a letter stating that they were receiving clean fill and that they would not hold GE liable for any subsequent problems, were given truckloads of PCB-contaminated material to use as fill in their backyards and construction projects.
The sheer magnitude and varied scope of this contamination has made the Pittsfield/Housatonic Site one of America’s most complicated PCB sites.

I am the R&D lab manager for a small company that uses various types of coatings in the product line. We looked into incorporating these nano-particles (additives) into our coatings a few years back. My research led me to much the same findings that have been mentioned here.
Firstly, these materials are enormously expensive. Despite this, they are touted as imparting near magical (cure-all) properties into whatever product they are formulated into thus making them worth the expense. Yet, the number of industries and companies that have moved to using this technology is rather limited thus far.
But their adoption has been held back by the cost — $500 a pound and up, Blakely said.

Secondly, the jury was still out then on how to safely handle these materials as well as the health issues of exposure to them. One can only imagine a particle size that allows penetration into the once impenetrable. What plant safety gear and clothing would be sufficient to protect someone working with these materials? And so I persuaded our company's management not to incorporate nano-particle additives into our coating formulations. The biggest selling point in my argument was not the health issues regarding myself and the other employees but the possible future blowback once these materials were in the hands of our customers. Yes, the possibility of lawsuits from our customers was the clincher. Concerns over my health and that of our other employees? Well, not so much.

This makes small pox contaminated blankets look like charity.
Oh, but corporations can do no wrong without government!
Yeah right!
Great work in helping to bring this to light.

nice thread OP, it's been a while since i had a new man made toxin to worry about.
the thing i love about this is that the only good reason to use buckyballs in any of these products seems to be that you can use the words "nano-technology" in the ad to make the product sound cutting edge, it's pure marketing..
the "nano-technology" makes the product both more desirable and more toxic. kind of like radioactive toothpaste, that worked out well!!
Although buckyballs spontaneously occur in nature from origins as simple as candle soot, their discovery is a very recent occurrence.
Convoys of United States Army tanks are rumbling across Kuwait this month-ready again to play a key role in war with Iraq. But before they fire a single shot, those tanks are already locked in battle with old foes: whipping desert sands, blistering sun, and even the air itself.
Each year, the axis of corrosion costs the U.S. Army $10 billion dollars-$2 billion for painting and scraping alone, labor-intensive work that's hazardous to people and the environment. So last fall, the Army's Tank-automotive and Armaments Command, Armament Research, Development and Engineering Center (TACOM-ARDEC) in Picatinny Arsenal, NJ asked a coalition of researchers at the New Jersey Institute of Technology, Clemson University, and the University of Illinois to do something about it. The command awarded them $838,000-and promised up to $1.5 million more-to find materials that combine self-healing characteristics with the ability to change color and sense structural damage or environmental changes. Dan Watts, the man leading NJIT's program, says their research has been pushed along by unexpectedly rapid advances in self-healing polymers and electronics made from carbon nanotubes that go "beyond the realm of interesting academic speculation and approach economic practicality."

More here, if interested....
nanoparticle growing in popularity as a bactericidal agent has been shown to be toxic to fish, according to a Purdue University study.

The nascent nanotechnology industry collectively cringed last week after a study showed that fish exposed to nanoparticles suffered brain damage. Critics say the much-hyped multibillion-dollar nano industry has a dark side few want to talk about.

I don't like alarmists, but buckyballs seem genuinely dangerous. Glad to hear someone with a professional background back up my initial "WTF?" reaction.

Do you know if the price has dropped since?
So far the only industries I'm seeing really using this are cosmetic, fabric, disposable sport supplies, & OTC medical supplies (like suntan lotions). Only. LOL. One too many industries if you ask me.

When you were researching this, did you ever get any details on what big cosmetic companies were doing to protect their employees that package the facial cremes?
This is why I'm a cynic. I'd like to think at some point they'd stop counting dollars in their head and realize they, their kids, and their loved ones will one day end up on the sh## end of the nano- stick. It half makes me think the andromeda strain isn't far off from a possible future reality.
Ethics? What a quaint notion.
Though a big for convincing your company to drop the idea.
