Language of instruction:

English

Assumed knowledge on:

Prior to the course it is assumed that the information of chapters 7 and 8 of the book used in this course (Walker, C.H.; Sibly, R.M.; Hopkin, S.P.; Peakall, D.B. (2006). Principles of Ecotoxicology) is known to the students.

Continuation courses:

TOX-31306 Environmental Risk Assessment of Chemicals

Contents:

This course gives an overview of different aspects playing a role in the challenging field of environmental toxicology. Toxicology itself already is very interdisciplinary, but environmental toxicology even adds (environmental) chemistry, earth sciences, biology of a wide range of species and ecology to this. The course is set-up as an integration between lectures, practicals, computer sessions, videos and excursion. The book 'Principles of Ecotoxicology' is used to develop a basis for the rest of the subjects in the course. About half of the lectures will focus on a variety of timely additional issues. In the practical part of the course you will use a set of experiments to identify two unkown chemicals based on their toxicity profiles. Applying a set of modern in vitro and in vivo assays you will address the toxicity of the unknown and compare this with literature data/ Based on this, the identity of the chemicals can be assessed. This will be presented both orally as well as in a small report.

Learning outcomes:

After successful completion of this course students are expected to be able to:
- summarise the most relevant terms, principles and methods in environmental toxicology;
- distinguish the main sources and types of environmental pollutants and assess their potential environmental fate;
- evaluate the characteristics of compounds, organisms and ecosystem for their consequences for environmental fate and effect propagation:
- design and execute toxicological dose-response experiments in a comprehensive way and analyse and critically discuss the results (written);
- create an experimental approach with meaningful endpoints to assess the environmental and human risk for a topical environmental contamination case;

Activities:

Lectures and the excursion will provide detailed information on the relevant topics of the course (learning outcomes 1, 2 and 3). An intensive practical will enable to the students to acquire hands-on experience in designing, performing and analysing experimental dose-response studies (learning outcome 4 and 5).
Lectures and excursion will be assessed at the individual level by the exam. Practical will be assessed by the written report and an oral presentation, group wise (2-3 persons per group). The case simulation (4 persons) will be performed in different and will be assessed by an poster presentation and a pitch presentation.

Examination:

Assessment will be based on two outcomes.
- exam: in this exam the theoretical base of environmental toxicology will be assessed, using multiple choice questions (60%);
- practical skills: this will be tested with a written report and a group presentation. This will also include work attitude (40%);

For both parts a minimum grade of 5 is needed
