What are the Challenges in Evaluating Safety and Toxicity?
Evaluating safety and toxicity presents several challenges, including heterogeneity in populations, variations in exposure levels, and the presence of confounding factors. Long-term studies are often required to assess chronic toxicity, but these can be resource-intensive and ethically complex. Additionally, emerging threats such as nanomaterials and endocrine disruptors pose new challenges for traditional assessment methods.
