2004 Strategic Environmental Assessment SEA5 Analysis of seabed sediment samples for heavy metals (North Sea)

As part of the UK Department of Trade and Industry's (now Department of Energy and Climate Change) ongoing sectorial Strategic Environmental Assessment a seabed survey programme (SEA5) was undertaken between August and early October 2003 for the UKCS areas lying between Scotland and Orkney and Shetland. This report summarises the sediment trace metal data generated from the analyses of selected samples from the study areas detailed: Fair Isle; Outer Moray Firth A; Outer Moray Firth B; Smith Bank; Southern Trench.

Strategic Environmental Assessment (SEA) data portal - The Strategic Environmental Assessment (SEA) data portal provides free access to available data and reports which have been produced through the UK Department of Energy and Climate Change SEA process. The site is run and managed by BGS on behalf of the Department of Energy and Climate Change (DECC). Many files can be downloaded directly from this website. Those that are too large to download can be ordered via the website for postal delivery from BGS.

Data Quality

This report was compiled by Harwell Scientifics under contract to Geotek Ltd as part of the UK Department of Energy and Climate Change's Offshore Energy Strategic Environmental Assessment programme. Sediment samples were collected between August and early October 2003. 79 samples were analysed for heavy metals (arsenic, barium, cadmium, chromium, copper, iron, lead, manganese, mercury, nickel, strontium, vanadium and zinc). The samples were dried in an oven at 30 C. The samples were then treated by strong acid extraction process (aqua regia) followed by multi-element analysis by ICP-AES (Perkin Elmer Opotima 4300DV) followed by in-house method HS/GWI/1075 issue 2 to analyse for arsenic, cadmium, chromium, copper, iron, lead, manganese, mercury, nickel, strontium, vanadium and zinc. The aqua regia digests were analysed for mercury by ICP-MS (Agilent 7500c) following in-house method HS/GWI/1002 issue 15. The barium content of the sediment was measured by ICP-AES following alkali fusion to ensure dissolution of all barium sulphate. As a quality assurance measure a reference material LGC 6138 and an inhouse material were prepared and analysed by the same method as the samples.
