What Are the Challenges in Chemical Prioritization?
Chemical prioritization poses several challenges, including:
- Data Gaps: Often, there is insufficient toxicological data available for many chemicals. - Complex Mixtures: Assessing the toxicity of chemical mixtures is more complicated than evaluating individual substances. - Evolving Science: Advances in toxicology and emerging contaminants require continuous updates to prioritization methods. - Regulatory Variability: Different regions may have varying regulatory frameworks, complicating global prioritization efforts.
