| Aim: To provide a general basic knowledge of environmental chemistry and ecotoxicology as a fundamental basis for understanding chemical pollution problems. Tools for evaluation of environmental fate and effects of chemicals are introduced in the context of environmental management and risk assessment. |
| Contents: The course mainly deals with environmental exposure and effect assessment of organic chemicals. Exposure and effect assessments are key elements in both Danish and EU classifications and risk assessments of chemicals. The exposure assessment covers the environmental chemical fate i.e. transport, degradation, intermedia transfer and partitioning of chemicals in different parts of the environment. Here processes like biodegradation, hydrolysis, photodegradation, sorption, volatilization, and bioaccumulation are fundamental for understanding the environmental behaviour of chemicals. The processes are related to the physico-chemical and chemical structure properties and to the characteristics of the environmental compartments (water, aquatic sediments, aquatic biota, soil, and air). Calculation exercises and computer-based models for distribution of compounds are used to illustrate the environmental chemical fate. The effect assessment covers ecotoxicological effects of chemicals. This subject is taught through lectures dealing with the theoretical aspects of toxicity testing and regulatory use of toxicity data. Furthermore, a series of laboratory exercises are carried out in groups of 3 students. The laboratory exercises include standard tests for biodegradation and biological effects on different groups of organisms (e.g. bacteria, algae, and crustaceans). |
