MSc Ecotoxicology

MSc in Environmental Pollution Management (Ecotoxicology)

An increasing number of chemicals is used by society today, which are also released into the environment. Environmental Pollution Management (Ecotoxicology) is concerned with their potential impacts on the ecosystem. It aims to investigate and discover effects of chemicals on biological systems in order to develop methods for risk management, as well as to predict ecological consequences.

The international "Master of Science program in Environmental Pollution Management (Ecotoxicology)" integrates concepts of Environmental Chemistry, Environmental Toxicology, Ecology, Pollution Management and includes Social Sciences and Economics as well. Due to its interdisciplinary and applied approach, the Program enables its graduates to analyze complex environmental problems and to develop practical solutions.

As environmental problems reach far beyond national borders, an international approach is necessary and the situation in developing countries needs special solutions.

The Master in Environmental Pollution Management (Ecotoxicology) is organized by the Institute for Environmental Sciences Landau and its graduates receive the full credits for the nine required topics of the Society of Environmental Toxicology and Chemistry’s Certification of Environmental Risk Assessors (CRA) program.

The Master of Science in Environmental Pollution Management (Ecotoxicology) is a tuition free graduation Program in Landau, Germany. The Program is taught in English and attended by students from more than 70 countries. In Landau, our Welcome Center offers video guides, personal support, and will accompany prospective students all the way: Starting with visa applications, finding accommodations, registering with local authorities, obtaining health insurance, and more to ensure an uncomplicated enrollment process here in Landau.

Course breakdown

ETX1: Methods in Ecotoxicology

You are introduced to methods according to Good Laboratory Practice (OECD) and get to know different ecotoxicological test systems that are used in a regulatory context. Students acquire the understanding of how to work under quality assurance systems, following OECD and GLP guidelines, which are then applied practically in an experiment and summarized in a report.

ETX2: Principles of Ecotoxicology

Students acquire the knowledge of terrestrial and aquatic ecotoxicology, i.e. the effects of chemicals on individual organisms. The curriculum further expands on ecotoxicological effects from to population up to the ecosystem level, how to identify and evaluate proper testing procedures. The module is concluded by learning strategies of how to address such environmental challenges in order to manage ecotoxicological risks and associated adverse outcomes.

ETX3: Tools for Complex Data Analysis

Students learn to design a study and select the corresponding tools for subsequent data analysis. They become able in linking scientific questions to the required methods of data analysis and data processing. With a deepening knowledge, ranging from univariate to multivariate or novel machine-learning approaches, students become more familiar with advantages and disadvantages of respective analysis tools.

ETX4: Effects of Chemical Stressors I

Students are taught the principles of toxicology by leading toxicological experts from the chemical industry. With this course, students acquire the knowledge of routes and reactions in the metabolism, mechanisms of cancerogenity, toxicokinetics, toxicodynamics and become able of deriving toxicological and pharmacological profiles. Knowledge is applied in the laboratory, conducting mutagenicity, developmental, and biotransformation experiments.

ETX5: Effects of Chemical Stressors II

Ecotoxicological knowledge is deepened, learning the interactions of chemical stressors with various organismic and higher-level structures that result in ecosystem alterations impairing their structure, function or ability to provide ecosystem services. Students are then introduced to Landau’s research coordinators and integrated into ongoing research, based on student’s preference, ability and interest. Thus, students gain a first glimpse into project planning and execution, as well as an early opportunity to become a member of Landau’s Institute for Environmental Sciences (iES) research teams.

ETX6: Environmental Analysis

The students gain advanced knowledge about the production, use and effects of various classes of environmental pollutants and their pathways in different ecosystems, including transfer, transformation and transport of pollutants. The course is complemented with practical lab exercises where students will learn sampling and extraction methods for pollutants followed by chemical analysis using GC- and LC-MS.

ETX7: Molecular Ecology I

The students become familiar with major topics in molecular ecology and basic theories of population genetics and phylogenetics. They get an overview of possible methods in molecular ecology and learn examples of their application. The students gain practical experience in phylogenetic analysis software and will be able to interpret the results. Finally, students become capable in applying and interpreting genetic data in the context of ecotoxicology, i.e. the potential effects of chemicals on genetics

ETX8: Models in Ecotoxicology

The students learn the basic principles of models to be used in the exposure or effect assessment in ecotoxicology. They gain insight into the restrictions, sources of errors and are enabled to quantify the uncertainty associated with them. They learn how to use models and to identify situations in which a modelling approach can be of help. They gain the ability to independently analyze a problem situation, to apply a suitable modelling approach and to interpret the results obtained.

ETX9: Risk Assessment and Management

The students acquire the principles of risk assessment and environmental pollution management of chemicals in Germany, the EU and internationally. They will become aware of the legislative and non-legislative background to risk assessment and risk management, the procedure and the role different stakeholders play. They learn to evaluate existing data in order to conduct deterministic and probabilistic risk assessments and to derive appropriate risk mitigation strategies. Students are introduced to software and other IT-solutions that are commonly used in the field of regulatory risk assessment and ecological evaluations for the registration of chemicals.

Detailed description of the study program and the modules:

Applied Module at External Organizations (AMEO)

The module AMEO is an 8-week internship, which can be performed at an external university or a governmental or industrial research institute in Germany or abroad. Students become familiar with working practice, requirements of the job market and career opportunities and can establish business contacts. They apply, confirm and expand knowledge and competences achieved during their study.

Following an introductory discussion with the supervisors, the students perform the (research) work on their own and discuss the obtained results regularly with their supervisors. The content depends on the actual research questions in the selected research organizations. Topics or possible positions will be suggested by the staff of the Institute for Environmental Sciences or maybe suggested by the students. The topics should be directly related to applied problems relevant in these external organizations and should ideally offer the students opportunities to apply their knowledge and skills in areas, which are not the particular research areas at the Institute for Environmental Sciences in Landau. They include, but are not restricted to the following areas:

  • Engineering aspects (e.g. hydrology, mitigation techniques)
  • Multimedia modelling
  • Food web modelling
  • Fish, bird or mammal ecotoxicology and risk assessment
  • Agricultural sciences
  • Socioeconomics
  • Specific aspects in regulatory ecotoxicology
  • Risk communication, economic or societal aspects

Research Project Course (RPC)

The students work independently on a research topic of the university for a total time of about 10 weeks. The topics depend on the actual research conducted in the various research groups. However, all topics do have an interdisciplinary character covering at least two different disciplines (e.g. chemistry and ecology, or physics and risk assessment). The students submit proposals for topics selected from a list provided by the teaching staff including a time and resource planning as well as an independently conducted literature search. Following an introductory discussion with the supervisor, the students perform the research work on their own and discuss the obtained results regularly with their supervisor. Following the practical work, the students write a report including the theoretical background, the methods used, the results obtained and a discussion of the results based on the relevant scientific literature. The students present and defend the outcome of their work at an oral presentation. Following successful completion, the students are able to plan a scientific work package, conduct the work, evaluate the results based on the relevant literature and present the outcomes.

The content depends on the actual research questions in the research groups associated with the Institute for Environmental Sciences. They include, but are not restricted to the following areas:

  • Chemical experiments in the lab
  • Environmental colloid chemistry
  • Environmental organic chemistry
  • Physical transport or transfer processes of environmental chemicals
  • Ecotoxicological lab tests
  • Ecotoxicological field studies
  • In situ or monitoring work in the field
  • Molecular genetics
  • GIS data analysis
  • Data analytics, modelling, and machine learning
  • Literature reviews
  • Exposure, effect or landscape modelling
  • Assessment or management of risks

In an opinion paper in the journal Integrated Environmental Assessment & Management, Harris et al. (the open access paper can be found here) identified the following requirements for the training of future Ecotoxicologists:

  • interdisciplinary training at the own university or at another institute or laboratory (see e.g. general learning target and AMEO module in the list of modules)
  • participation of business and government experts in academic research and guest lectures (see e.g. modules ETX4 Effects of chemical stressors I and ETX9 Risk Assessment and Management in the list of modules)
  • training in the basic principles of test guidelines and QA and GLP regulations that are used in industry (see module ETX1 Methods in Ecotoxicology in the list of modules)
  • training that allows considering the potential regulatory impact of academic research throughout the research process (see e.g. modules ETX2 Principles of Ecotoxicology and ETX9 Risk Assessment and Management in the list of modules)

Landau's Master in Environmental Pollution Management (Ecotoxicology) program provides all of these skills and opportunities allowing students to become well-educated Ecotoxicologists suited to the current and future job market.

The Program enables the graduates to conduct independent scientific work and prepares in particular for independent and leading positions in the numerous emerging fields of Environmental Pollution Management (Ecotoxicology). The graduates are able to take responsibility in a professional manner in: Scientific facilities and research institutes, authorities, public offices and ministries with a regulatory role, Non-governmental organizations, industry and consulting enterprises. The international orientation of the program qualifies graduates for a global job market. In addition, the Master program prepares for a PhD study.


Landau’s Master of Science program in Ecotoxicology is the first program cooperating with the Society of Environmental Toxicology and Chemistry - Europe (SETAC) on their “Certification of Environmental Risk Assessors” (CRA) program, which provides an internationally recognized certification for environmental risk assessors. Graduates from Landau receive the full credits for the nine required CRA program topics (modules). Furthermore, graduates already on an environmental risk assessment job can consider this job as equivalent to the internship required by the CRA program and can directly enroll for the Graduate Environmental Risk Assessor (GRA) examination. More information is available on


The Institute for Environmental Sciences is globally connected through international research projects and student exchange programs. The international nature of the Program is achieved through numerous international research and teaching staff, regular seminars from guest lecturers from abroad, and possible internships all over the world.
