  • Explain how endocrine disruptors are dealt with under the REACH Regulation
  • Outline the key issues related to the assessment of endocrine disruptors

Acute Toxicity
  • Define the term acute toxicity and explain how it differs to repeated dose toxicity
  • Explain why it is not possible to use acute toxicity data to predict repeated dose effects
