WASHINGTON (CN) - Citing their toxicity and persistence in the environment, the EPA has proposed notification requirements for all significant new uses of multi-walled carbon nanotubes.
Under the proposal, the Environmental Protection Agency would receive notice of any person's intent to manufacture, import, or process for a new use of the nanotubes before that activity begins.
The Toxic Substance Control Act authorizes the EPA to require 90 days advance notice of the intent to use regulated substances in a new way, to prevent uses that may prove harmful to the environment or to people.
The agency has identified EPA multi-walled carbon nanotubes as toxic due to their impact on lung tissue where the needle like structures can become embedded in the lung, causing inflammation and formation of lesions known as granulomas which can reduce lung capacity and other symptoms similar to those caused by exposure to asbestos.
