Phase out persistent, bioaccumulative or highly toxic chemicals

Area of Science:

• Environmental Science
• Toxicology
• Public Health Policy

Background:

• Persistent, bioaccumulative, and/or highly toxic (PBT) chemicals, including lindane, lead compounds, brominated flame retardants, and organophosphate pesticides, are still in commerce.
• Strong evidence indicates these chemicals threaten human and ecosystem health.
• The inherent characteristics of these chemicals make them difficult to manage safely, posing risks to workers, the environment, and ecosystems.

Purpose of the Study:

• To highlight the need for prioritizing chemicals that cannot be safely managed for phase-out.
• To emphasize the necessity of a transparent process for identifying and prioritizing chemicals for phase-out.
• To identify the lack of governmental authority and efficient policy instruments for restricting the use and release of high-priority chemicals.

Main Methods:

• Literature review of existing chemical management policies and their limitations.
• Analysis of the characteristics of persistent, bioaccumulative, and toxic chemicals.
• Assessment of governmental (federal, state, local) authority and policy instruments for chemical restriction.

Main Results:

• Certain hazardous chemicals remain in commerce despite known risks.
• Existing management strategies are insufficient to mitigate threats posed by these chemicals.
• Governmental bodies at all levels lack effective policy tools to phase out problematic chemicals.

Conclusions:

• Chemicals that cannot be managed safely must be prioritized for phase-out.
• A clear and transparent process is required to identify and prioritize chemicals for elimination.
• Development and implementation of effective policy instruments are crucial for phasing out hazardous chemicals at all governmental levels.
