Learning Outcomes and Competencies Students will:
  • be able to explain the scientific questions which are dealt with within toxicology and ecotoxicology.
  • be able to explain and assess toxic effects, poisons and poisonous effects on the human organism (including side effects of drugs and toxic effects of [poisonous] plants).
  • be able to develop experimental strategies for researching the harmful effects of specific chemical substances or drugs.
  • be able to analyse and interpret results of toxicological studies.
  • be able to describe basic concepts / range of tasks within ecotoxicology.be able to name relevant sources of pollutants, their deposition as well as their behaviour in the environment.
  • understand the term bioaccumulation (biomagnification & bioconcentration) and explain this using examples
  • have an overview of the direct and indirect effects of chemicals on individuals, populations and ecosystems, and explain this using historical examples.
  • know a range of methods to detect toxic effects of substances on organisms.
  • be able to carry out a simple risk analysis of a plant protection agent.
  • learn about leading organisations, their tasks and research fields in the field of ecotoxicology in Switzerland.
Module Content Lectures are conducted in 3 parts:

1)Toxicology: interactions between foreign substances and the human organism; how substances are metabolised in and excreted from the body; what toxic effects can occur on different organ systems and tissues
2) Ecotoxicology: Interaction between chemical substances and the environment: deposition, accumulation in organisms, negative effects on organisms, populations and ecosystems
3) Testing methods and risk assessment: Experimental strategies and tests performed for risk assessment, e.g. LD-50 determinations, etc Ecotoxicological tests for monitoring aquatic systems. Risk assessment of plant protection agents
