This course introduces the principles of toxicology, exploring the adverse effects of xenobiotics on living organisms. It covers the history of toxicology, biochemical and molecular toxicology, and the roles of biotoxins. Key topics include carcinogenesis, teratogenesis, mutagenesis, and biotransformation of toxicants. The course also examines toxic responses in various body systems such as blood, liver, kidney, immune and respiratory systems, and the eye. Students will learn about assessment methods and the application of toxicology in safety evaluation.

EMT407 · UNIT 2 BIOCHEMISTRY CELLULAR AND MOLECULAR TOXICOLOGY

Cleopatra’s (69–30 BC) knowledge of natural primitive toxicology permitted her to use the more genteel method of falling on her asp. The Romans too made considerable use of poisons in politics.

What you should be able to do

  1. Define toxicology and its major sub-disciplines.
  2. Explain the mechanisms of action of various toxicants.
  3. Identify the target organs and systems affected by specific toxins.
  4. Describe the processes of biotransformation and excretion of toxicants.
  5. Apply toxicological principles to risk assessment and safety evaluation.
  6. Evaluate the impact of environmental factors on toxicological outcomes.
