"And what about new nanomaterials?
The original Lautenberg proposal would have allowed EPA to regulate novel nanomaterials more rigorously. It contained language that would have updated the definition of “chemical substance” to reflect the new science of nanotechnology, which exploits changes in size and shape of materials to manipulate their behavior, but also may present new health risks.
The Lautenberg-Vitter bill would maintain the status quo. It would give EPA no more power to oversee nanotechnology, despite the rapid development of these materials. That’s a serious gap. As a chemist specializing in nanotechnology, I know that certain nanomaterials can present greater hazards to health and the environment than ordinary ones. The EPA needs to have the ability to distinguish among different material forms to ensure that both new and existing nanomaterials are safe for us all."
