EPA proposes policy on nanomaterials in pesticide products

The U.S. Environmental Protection Agency announced today it plans to obtain information on nanoscale materials in pesticide products. Under the requirements of the law, EPA will gather information on what nanoscale materials are present in pesticide products to determine whether the registration of a pesticide may cause unreasonable adverse effects on the environment and human health. The proposed policy will be open for public comment.
