CHEMISTRY OF THE ENVIRONMENT - 2022/3
Module code: CHE1034
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
An introduction to the numerous interlinked chemical processes that take place within the Earth’s environment, and the impact they may have for life on Earth.

|Assessment type||Unit of assessment||Weighting|
|Examination||EXAM - 2.0 HOURS||70|
No alternative to Examination and extended essay
The assessment strategy is designed to provide students with the opportunity to demonstrate successful achievement of the learning outcomes.
Thus, the summative assessment for this module consists of:
- 2.0 hour examination 70% (addresses LOs 1-4)
- Coursework (2000-2500) 30% (addresses all LOs, particularly 3 and 5)
Students are required to produce a detailed plan for the extended essay; tutorial sessions with problems and/or discussion topics ensure that students engage with the module and are able to measure their own progress with it.
Detailed feedback is provided on the essay plan and on the extended essay – written on each printed piece of work and using the feedback form. Similar feedback given on the poster and ‘newspaper’ front page generally and individually.
- To provide an introduction to some of the fundamental concepts and principles of environmental chemistry
- To provide an introduction to the type of chemical processes occurring naturally and as a result of anthropogenic activities within the atmosphere, biosphere, hydrosphere and lithosphere
- To provide an understanding and rationalisation of some of the key environmental problems currently confronting society, and a consideration of possible of the solutions

Tutorial Hours: 6
Methods of Teaching / Learning
The learning and teaching strategy is designed to:
allow students to understand the key processes operating within the environment, relate them to their current understanding of chemistry, and to consider how environmental problems may be foreseen and avoided.
The learning and teaching methods include:
lectures, seminars, tutorials, consideration of case studies, research for extended essay. There are 33 hours of lectures and 6 hours of tutorials/seminars, arranged flexibly to reflect class cohort and topics of discussion.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
