Nanotech and the oil spill
As BP and government agencies struggle to stem the devastating flow of oil now hitting the Louisiana coast, there is growing desperation to find a solution -- and fast. Green Earth Technologies, Inc. (GET) is seeking approval from the Environmental Protection Agency (EPA) to disperse manufactured nanoparticles in the Gulf of Mexico to remedy the oil spill. IATP and more than a dozen other organizations think this is a bad idea.
In a letter organized by Friends of the Earth, IATP and others urged EPA to deny approval of this project. Manufactured nanoscale chemicals measure less than 300 nanometers. A human hair is about 80,000 to 100,000 nanometers. The large surface to volume ratio of nanoparticles is supposed to prevent the oil from coagulating and then being carried by ocean currents to damage coastal areas. The problem is that nanoparticles have been found to be toxic to humans, mammals and aquatic life. Manufactured nanoparticles can travel up the food chain from smaller to larger organisms. In this case, the exact composition of nanoparticles being used by Green Earth Technologies are trade secrets so the extent of toxicity is unknown.
The groups wrote, "We understand the enormous technical and regulatory challenges posed by the oil spill. However, two wrongs do not make a right. Exacerbating this grave situation by allowing GET to add pollutants to contaminated land and water should not be allowed, especially considering that the GET nanoparticles could be impossible to recover once introduced into the environment. We fully oppose this irresponsible, unscientific and dangerous experiment."
IATP has been looking into food and agriculture applications of nanotechnology and the lack of strong regulations to protect the environment and public health.
