How should engineered nanomaterials be regulated for public and environmental health?

Abstract

A central ethical and policy issue regarding minimizing and managing risks of engineered nanomaterials (ENMs) is whether existing legal frameworks sufficiently protect public health and the environment. This article argues that policymakers should (1) use existing laws to regulate ENMs and the best available evidence to inform appropriate levels of regulation and (2) support additional research on risks of ENMs. Were they to do so, public health and environmental risks of ENMs could be minimized and managed without sacrificing their potential clinical, social, and economic benefits.
