Full coverage (a dedicated course)
No species is addressed specifically
|Details on the topic or technology covered:||
· Characterisation of ecological effects. Stressor-response analysis. Quantification of ecological effects: LC50, EC50, NOEC.
· Ecological effects on different ecological levels: single species tests, population studies, ecosystem-level tests (microcosm’s, mesocosm´s and field studies).
· Ecological risk assessment: field, objectives and concepts
· Ecological risk assessment as a decision-making tool: ecological risk assessment and risk management, participants, quality assurance
· Exposure characterisation. What is exposure? Definition.
· Exposure analysis: exposure pathways, fate and transport models.
· Planning laboratory tests. Selection of appropriate end-points. Tiered approach.
· Risk characterisation. Quantification of risk. Uncertainty assessment.
· Risk assessment tools 1. Fate and transport models. Modelling exposure of biotic stressors: population dynamics models. Toxicokinetic and toxicodynamic models. SAR and QSAR models.
· Stressor characterisation. Chemical, physical and biological stressors (exotic species and GMOs). Secondary stressors. Interaction of stressors: graph theory.
The student will learn how to:
· Carry out an ecological risk assessment in relation to a given problem and to present the outcome of the risk assessment in a form that may be used to devise a risk management measure.
· Define environmental/ risk management measures based on scientific principles and interpret an ecological risk assessment in terms of the process and results and.
|Accreditation body and/or authority that approved the education or training:||
by the university
Students are required to carry out an ecological risk assessment for a given substance and submit the assessment in writing. Assessment is based on the following criteria:
· Correct application of the environmental risk assessment algorithm
· Comprehensive description of the stressor
· Selection of appropriate end-points
· Appropriate quantitative estimation of stressor-response relationships, proper application of statistical methods (probit, ANOVA)
· Proper quantification of risk
