Several challenges can complicate the hazard identification process:
1. Data Gaps: Sometimes, there is insufficient data on the toxicity of certain substances, making it difficult to assess their hazard accurately.
2. Variability in Data Quality: The quality of data can vary, and not all studies may meet the rigorous standards required for hazard assessment.
3. Complex Mixtures: Identifying hazards in complex mixtures of chemicals can be challenging due to the potential for interactions between different components.
4. Emerging Hazards: New substances and technologies continuously emerge, requiring ongoing research and updated hazard identification methods.
