Using emerging science to inform risk characterizations for wildlife within current regulatory frameworks.

Area of Science:

• Environmental toxicology and risk assessment
• Wildlife ecotoxicology
• Environmental regulation and policy

Background:

• Current regulatory frameworks aim to mitigate anthropogenic chemical impacts on terrestrial wildlife.
• These frameworks address both new and existing chemicals, encompassing prospective (pesticides) and retrospective (contamination) risk assessments.
• Recent scientific advancements hold potential for enhancing wildlife risk estimation.

Purpose of the Study:

• To evaluate North American and European wildlife risk assessment regulations for their compatibility with emerging scientific methods.
• To identify specific areas where new science can refine wildlife risk characterization.
• To pinpoint future research needs in wildlife ecotoxicology and risk assessment.

Main Methods:

• Comparative analysis of regulatory frameworks in the United States, Canada, and Europe.
• Review of recent scientific literature on advanced methods for wildlife risk assessment.
• Case examples illustrating the application of emerging science in risk characterization.

Main Results:

• Existing regulations in North America and Europe vary in their capacity to integrate novel scientific approaches.
• Emerging science, such as advanced exposure modeling and toxicogenomics, can significantly improve the accuracy of wildlife risk assessments.
• Several key areas for future research were identified, including the development of standardized methods for incorporating new data and addressing cumulative effects.

Conclusions:

• Regulatory frameworks need adaptation to fully leverage emerging scientific advancements for more robust wildlife risk assessment.
• Integrating new methodologies can lead to more precise and protective environmental policies for terrestrial wildlife.
• Further research is crucial to bridge the gap between scientific innovation and regulatory implementation.
