Biomarkers – a user friendly approach

2021-07-08T15:16:05+00:00Categories: 05 Suborganism-level ecotoxicology, 2021, Past Courses|

14 – 18 June 2021 | Department of Biology & CESAM, University of Aveiro, Portugal | 2 credits

Advanced course on biomarkers


 This one-week course held at DBio & CESAM (University of Aveiro, Aveiro, Portugal) aims to provide knowledge about using biomarkers and their advantages (and disadvantages) to assess the ecologically relevant impact of stressors in the environment. Moreover, the ecological relevance and ranges of applicability of biochemical/behavioural/analyticaltools will be shown for particular classes of pollutants by linking their effects with alterations at higher levels of biological organization. Furthermore, the practical use of a biomarker approach in distinct taxa will be demonstrated, showing the usefulness of this set of tools independently from the analysedecosystem. This new approach has been successfully used by staff members of this course in soil ecotoxicology, freshwater ecotoxicology, marine ecotoxicology, wildlife ecotoxicology, biomonitoring, characterization of drug toxicity and nanotoxicology. The course is composed by theoretical lectures, by the presentation and discussion of several of our own case studiesduring which test procedures will be discussedand students will have the opportunity to understand the pros and consof several techniques. Thecourse is targeted to scientists, PhD and MSc students (with a background in Biology, Environmental Sciences and Engineering, Chemistry, andrelated fields) and other professionals involved in decision-making and environmentalmanagement. All lectures and training sessions will be held in English.

Online Course: Aquatic Effect Assessment of Plant Protection Products

2021-07-08T15:16:26+00:00Categories: 2020-Sep, Past Courses, Specialised course|

21 Sep – 6 Oct 2020 | Online course | Central European Summer Time (GMT+2)


Do you want to apply existing guidance and new approaches in risk assessment? But don’t know how? In the authorization of plant protection products the potential risks of active ingredients and products for the environment are assessed at EU and MS level using governmental guidance. This course focuses on aquatic effects and offers a combination of lectures, hands-on exercises and virtual classroom. This combination of theory and practice is an excellent opportunity to deepen your knowledge and understanding of aquatic effect assessment and to improve your skills.

Back home you can apply new knowledge and approaches straight away in your daily work. In this course we focus on aquatic effect assessment and the linking of exposure to effects, including consistency of the tiered approach, issues in each of the tiers, geomean approach, species sensitivity distributions, modified exposure tests, micro- and mesocosm studies, realistic worse-case exposure profiles, statistical power, recovery option and General Unified Threshold models of Survival;  Refined Exposure testing and TK/TD modelling.After successfully attending this advanced online course you will have deepened and actualized your expertise level on all topics included in the programme.

Target Audience

This course aims at professionals using guidance for the authorisation of plant protection products, for Tier 1 up to 3:

  • Regulators working for admission authorities who apply the guidance for their dossier evaluations
  • Consultants and business representatives working for industry and or consulting agencies who apply the guidance for dossiers (evaluation, preparation and submission)
  • Scientists performing lower and higher tier research (experimental and modelling), applying the latest and newest available guidance

This online course is an advanced course and handles aquatic effect assessment at the applied level. We ask at least a Bachelor degree or similar level in natural sciences and in-depth experience with the Tiered approach for effects on the aquatic ecosystem.

Mechanistic Effect Modelling Workshop 2019

2020-05-01T19:15:26+00:00Categories: Meeting News, Past Courses|

21-22 February 2019 | Hirschberg, Germany


The course introduces the principles of effect modelling (TK/TD and population models), model development and documentation, important terminology and good modelling practice. The state-of-art of effect modelling in the context of risk assessment is addressed. Group exercises are intended which reflect our experience in project work on the one hand and provide the participants with hands-on experience in model applications on the other hand as well as the opportunity for model exploration. One main aspect is an open discussion with our motivated team of competent scientists in a relaxing atmosphere.

  • Getting familiar with ‘modelling’: Basic understanding of what modelling is, using an interactive presentation and simple example situations
  • The basics of modelling: introduction to modelling basics, the modelling cycle and important terminology
  • Modelling in environmental risk assessments: the different types of models and their applicability to ERA, good modelling practice
  • Organism-based modelling: information on possibilities and state-of-the art. The main focus is the General Unified Threshold model for Survival (GUTS) which is presented in detail, followed by example case-studies from our experience with project work in this field.
  • Population modelling: information on possibilities and state-of-the art. The main focus is spatially-explicit individual based models, usually 2 of which are presented in detail, followed by example case-studies from our experience with project work in this field
  • Hands-on experience is planned with a set of models ((at least one TK-TD and two different spatially explicit individual based population models) where the participants work in groups to explore the simulation tools which we make available and to address given questions using simulations for which they will analyse / check / compare and interpret the output.
