This course offers an introduction to the chemistry and toxicology of chemical environmental pollution, one of the hallmarks of the Anthropocene. Topics include:
Background:
In our modern society, we are constantly surrounded by an extensive array of chemicals, encompassing a diverse range of applications and functions. Among these are chemicals known for their impact on the environment and human health, such as PFAS (per- and polyfluoroalkyl substances), pesticides, microplastics, and countless others. With growing awareness and concern about their presence and impact, these pollutants are nowadays a focus of attention of scientific research and public debate.
As these chemicals infiltrate our surroundings, they navigate through various pathways, penetrating ecosystems, food chains, and ultimately, organisms, including humans. The consequences of their presence can be profound, exerting adverse effects on both environmental and human health.
This course offers an introduction to the chemistry and toxicology of environmental polluting chemicals and the chemical analyses of different types of environmental pollutants in a variety of environmental and biological compartments.
The course will first focus on the behaviour of chemical pollutants. Where will the chemicals end up, do they bioaccumulate or biotransform in living organisms and what are the (bio)degradation processes?
Subsequently, the course will focus on the environmental risk assessment of chemicals, on adverse effects of environmental pollutants, and on bioassays and effect-directed analysis.
Lastly, it covers methodologies for detecting and quantifying chemical pollutants in soil, sediment, water, and biota.
At the end of the course, all topics will be combined and integrated into the environmental assessment of a selected chemical pollutant.

This course consists mainly of lectures (6 hours a week) with a working group devoted to exercises using partitioning coefficients to calculate the distribution of chemicals between environmental compartments. The course includes an assignment and an oral presentation of the results of this assignment in a poster format and an oral presentation. Several hours a day self-study.

The final grade is calculated from the grade of the exam (67%), assignment poster (25%), and oral presentation (8%). The minimum grade for the exam has to be 5.0. The minimum grade for the poster has to be a 6.0. If resubmission of the report or poster is needed a maximum grade of 6.0 will be assigned.
The assignment consists of an independent assessment of the environmental risks of a chemical based on information
retrieved from the literature. The assessment should include the following information on the selected chemical:
• Sources and emissions
• Most relevant environmental compartment
• Methods to analyse the chemical in this compartment
• Predicted or measured concentrations in this compartment
• Toxicity for organisms in this compartment
• Risks for organisms in this compartment based on a comparison of concentration and toxicity
Results and conclusions of the assessment are reported in a poster and an oral presentation of the poster.
