1. Develop a strong rationale for which metals will be included within (or excluded from) your Dee Estuary Report; for example, two aspects that should be considered are: 1) potential sources; and 2) toxicity and possible impacts on natural ecosystems and human health. This rationale should be included clearly within the report, and there should be a (very) strong justification for any decision to ignore parts of the full metals concentrations dataset.

2. Initiate writing of a short draft Materials and Methods section for the Dee Estuary Report (Assignment Part 2, 70%). Refer to the specific assessment coversheet for guidance on what content to include.
3-Site G and H, This Excel file includes the metals concentrations for the Site G saltmarsh sediment core sample nitric acid extraction solutions. Some data processing will be required.
The report should include:
4.two aspects that should be considered are: 1) potential sources; and 2) toxicity and possible impacts on natural ecosystems and human health.
5 Dee estuary metals concentrations data should be summarised to tables of descriptive statistics (average, error, range), use of appendices for fuller data tables, and graphs to show to the reader clear spatial and temporal patterns in metals distributions within the Dee estuary. The concentrations datasets should be analysed and interpreted.
6 Initiate (or continue) identification of appropriate scientific journal articles focused on estuarine metals pollution (e.g. by a Web of Science search) and start background reading to assist with your own assessment of the Dee estuary metals datasets. The identified articles also will give you ideas on how the metals concentrations data can be presented, analysed and interpreted.
7 for example, two aspects that should be considered are: 1) potential sources; and 2) toxicity and possible impacts on natural ecosystems and human health. This rationale should be included clearly within the report, and there should be a (very) strong justification for any decision to ignore parts of the full metals concentrations dataset.
8 Identify how your narrative can be supported by assessment of the Dee estuary metals datasets against Sediment Quality Guidelines (SGQs) and other metals pollution indices. Undertake the required analyses and start to embed within your Dee Estuary Report integrated Results and Discussion section; consider how you could/should break-up this important part of the report into sub-sections, each with a discrete heading.
9 Consider how you could include statistical analyses to support the narrative within your Dee Estuary Report.
10 Look at papers that have analysed n-alkanes in polluted estuary sediments to find:

How do the authors distinguish petroleum pollution from natural n-alkanes?
What levels of n-alkane pollution were measured?
How were these levels presented in figures and tables?
