Module description
This module offers you the opportunity to study the impacts of chemicals on animals (including humans and plants in the environment). Ecotoxicology is highly interdisciplinary, and this module will cover aspects of environmental biology and chemistry, animal physiology, behaviour, molecular biology, and chemical risk assessment. The module is taught by world leading researchers in ecotoxicology with specialisms in areas including endocrine disruption, pesticides, plastic pollution and the effects of human drugs on wildlife.
Module aims - intentions of the module
This module aims to develop your awareness of the major current theories and concepts in the field of ecotoxicology. The intention is to give you a critical understanding of the responses of organisms to pollutants, with a particular emphasis on the aquatic environment, and how this can impact individuals, populations and ecosystems. The module also aims to develop your understanding of some of the legislation aimed at minimising pollution as well as some of the methods used assessing the potential impacts.
Through lectures, seminars, directed reading and self-study, you will develop skills in interpreting, debating, reviewing, and summarising concepts and data relating to the impact of pollutants in the environment.
Accessibility Statement:
Some of the formative in person teaching sessions are interactive and can involve informal group work (although students are welcome to work alone during these times). The summative assessment consists of two pieces of written work. The first is an on-line, time-limited data handling paper requiring interpretation of experimental design and results/figures. The second is a piece of coursework comprising an environmental risk assessment on an allocated topic for which you are expected to use the information provided to design a small program of work to assess the impact of a chemical in the environment, including justification for your choices of each aspect of the designed work.

Syllabus plan
Through lectures and seminars, the module will cover the following interrelated topics:
- Introduction to, and principles of, toxicology and ecotoxicology
- The effects of various pollutants of current importance in the environment, including endocrine disruptors, plastics, pesticides and pharmaceuticals
- Impacts of pollutants on organisms at the individual, population and ecosystem levels
- Aspects of environmental protection including the environmental risk assessment and some of the methods used to measure the impact of pollution on the environment
Seminars to help develop skills in experimental design, the principles of environmental risk assessment and scientific data handling

Re-assessment notes
Deferral – if you miss an assessment for certificated reasons that are approved by the Mitigation Committee, you will normally be either deferred in the assessment or an extension may be granted. If deferred, the format and timing of the re-assessment for each of the summative assessments is detailed in the table above ('Details of re-assessment'). The mark given for a deferred assessment will not be capped and will be treated as it would be if it were your first attempt at the assessment.
Referral - if you have failed the module (i.e. a final overall module mark of less than 40%) and the module cannot be condoned, you will be required to complete a re-assessment for each of the failed components on the module. The format and timing of the re-assessment for each of the summative assessments is detailed in the table above ('Details of re-assessment'). If you pass the module following re-assessment, your module mark will be capped at 40%.
