Phase out persistent, bioaccumulative or highly toxic chemicals.

Chemicals such as lindane, lead compounds, and some brominated flame retardants and organophosphate pesticides are examples of persistent, bio-accumulative, and/or highly toxic chemicals that continue to be used in commerce, although strong evidence exists that they pose threats to human and ecosystem health. These and other chemicals, by virtue of their characteristics, are very difficult to manage without unacceptable threats to workers, the environment, or ecosystems. Chemicals that cannot be safely managed should be prioritized for phase out.
