Environmental Chemistry 1: Water-solid-air interactions

EART27001 Environmental Chemistry 1: Water-solid-air interactions 10 Semester 1 Undergraduate Level 5 Greg Holland Unit coordinator 1 FHEQ level (Framework for Higher Education Qualifications) ' Middle part of Bachelors ' European Credit Transfer & Accumulation System Rating : 5.0 This module will cover the physical and chemical properties of environmental fluids and gases, including low temperature equilibria with solid phases and introductory kinetics. In the first part of this course the rationale for considering the importance of water-solid interactions are introduced in a holistic manner. Topics that will be discussed include: solubility, precipitation and equilibrium dynamics; adsorption on mineral surfaces; stability of minerals related to the activity of hydrogen ions and electrons (Eh-pH diagram); pollution mobility and kinetics in aquatic environments; and water pollution, toxins and nutrients. In the second part the chemistry of water-gas interactions will be explored in more detail. Topics that will be discussed include: solubility of gasses in water; greenhouse gas fluxes, gas kinetics and oxidation; water vapour and aerosols; hydrogen and oxygen isotopes and the meteoric water line; and production of gaseous pollution (including toxicity).

Learning during this course builds from one week to the next, with a weekly 1 hour lecture supported by a 2 hour practical class. Examples classes will be given in weeks 1, 2, 3, 8, and 9. Practicals will include themed discussion sessions regarding specific topics and calculation exercises. To be successful it is essential that students attend every lecture, example, and practical class, and revise the previous week’s material between classes. Links relevant to the lectures and practicals will be posted online. Formative quizzes will be used to give the students the opportunity to gauge their conceptual understanding of the course material and monitor their own progress through the course. Feedback on these quizzes is direct/immediately. Lab based practicals will provide the opportunity to apply and extend the student’s knowledge as well as to learn some valuable lab skills. The assessment for this course comprises an exam (50%) and two assessed lab based practicals (50% total, 30% and 20% respectively).</div>  1 Written exam 50% 8 Practical skills assessment 50% <table border="1" cellpadding="1" cellspacing="1" style="width:500px;"> <tbody> <tr> <td>Assessment Type</td> <td>% Weighting within unit</td> <td>Hand out in dates</td> <td>Length</td> <td>How, when and what feedback is provided</td> <td>ILO tested</td> </tr> <tr> <td>Exam</td> <td>50</td> <td>January exam period</td> <td>1.5 hours</td> <td>Written feedback will be provided when marks are released.</td> <td>1-5</td> </tr> <tr> <td>Pratical on aqueous chemistry</td> <td>30</td> <td>Mid Novemeber</td> <td>Max 6 pages</td> <td>Written/oral feedback will be provided when marks released</td> <td>1-5</td> </tr> <tr> <td>Practical on atmospheric chemistry</td> <td>20</td> <td>Mid December</td> <td>Max 6 pages</td> <td>Written/oral feedback will be provided when marks released</td> <td>2,4,5</td> </tr> </tbody></table>  <table border="1" cellpadding="0" cellspacing="0" width="0"> <tbody> <tr> <td style="width:204px;"> Pre-requisite units</td> <td style="width:436px;"> 1st year Earth & Planetary Science or Environmental Science</td> </tr> </tbody></table>  BSc (Hons) Earth and Plan Scie BSc (Hons) Earth (Geochemistr) Second Year Mandatory MEarthSci (Hons) Ea and Pl Sci MEarthSci (Hons) Earth (Geoch) Second Year Mandatory MEarthSci (Hons) Earth Industr MEarthSci EPS w IE (GeoChem) Second Year Mandatory MEarthSci (Hons) Earth Abroad MEarthSci EPS w YA (Geochem) Second Year Mandatory MEarthSci (Hons) EPS with Res MEaSc (H) EPS w R (GeoChem) Second Year Mandatory Introduction to Geochemistry, Krauskopf and Bird. 1995.
