Learning, Teaching and Assessment (LTA) Approach:
Introductory lectures and tutorials which incorporate problem solving and data interpretation exercises (LOs 1-6) are used to develop knowledge and understanding together with scientific and employability skills. This enables students to engage with research literature. Students will work in groups in the laboratory practicals to set up experiments which will allow them to generate data for hazard assessment (LO6).


Formative Assessment:
Formative assessment occurs in tutorials: data interpretation questions similar to those presented in the final exam are attempted by students in class with guidance and immediate feedback from the tutor. A formal examination at the end of the module assesses knowledge, understanding and skills in the interpretation of scientific data and application of data to problems.

Summative Assessment:
A laboratory report assesses analysis, presentation, interpretation and discussion of results from one of the laboratory practicals. This builds upon analysis and interpretation skills incorporated in tutorials. Formative assessment comprises analysis and reporting of data similar to the assessed lab report but using a different dataset from a different, but similar, experiment. Feedback on the formative assessment is important for successful completion of the laboratory report; therefore, the formative assessment is required rather than optional.

Description of module content:

In this module you will study the effect of pollutants on living systems (from cell to individuals and ecosystems) and the methods used to assess toxicity. You will practice bioassay design and interpretation including experimental laboratory work and computation of relationships between exposure and response to toxic substances. You will interpret and apply the findings of field and laboratory studies from the literature and learn to apply scientific information for environmental protection. You will learn about important pollutants such as pesticides, metals and endocrine-disrupting chemicals. You will also learn about the sources and environmental fate of pollutants, their uptake into living systems and transfer through living systems.
Subject matter: Introduction to toxicology and ecology and their core concepts. Transport and fate of contaminants in the abiotic environment and within organisms and ecosystems. Hazard assessment and risk assessment in the context of environmental pollution. Experimental design for toxicity bioassays. Effects and mode of action of pollutants. Methods for environmental monitoring and environmental protection. Data interpretation. Short-term and long-term toxicity tests will be conducted and the resulting data analysed.

Learning Outcomes for module:

Upon completion of this module you will be able to:
LO1: Compare and contrast the effects, disposition and mode of toxic action of pollutants.
LO2: Critically reflect on the means by which pollutants are taken up and transferred through living systems and communities.
LO3: Examine the relationship between exposure and response for various toxicants, including the estimation of EC50 values.
LO4: Evaluate methods used to assess the toxic effects of individual and multiple pollutants on organisms, populations and ecosystems.
LO5: Apply knowledge of the disposition and effects of toxicants and understanding of the environmental risk assessment process to assess the likelihood of environmental harm.
LO6: Conduct, analyse and report the results of an experiment.
