Title

2003 Strategic Environmental Assessment SEA4 Sample analysis - Particle Size Analysis and Heavy Metal analysis, Atlantic margin (north UKCS)

Abstract

This report contains heavy metal concentrations (As, Ba, Cr, Cu, Cd, Fe, Hg, Pb, Mn, Ni, Sr, V and Zn) and sedimentological characteristics (particle-size analysis) which were determined in respectively 61 and 68 samples for the Atlantic margin Department of Trade and Industry's (now Department of Energy and Climate Change) Strategic Environmental Assessment (SEA4) . A spreadsheet of data is available.

Lineage

Heavy metal concentrations and sedimentological characteristics in sediment samples were determined in respectively 61 and 68 samples by the Netherlands Institute of Applied Geoscience TNO - National Geological Survey (NITG-TNO) as part of the UK Department of Energy and Climate Change's Offshore Energy Strategic Environmental Assessment programme. Trace and heavy metals (As, Ba, Cr, Cu, Cd, Fe, Hg, Pb, Mn, Ni, Sr, V and Zn) were extracted by aqua regia and analysed by inductively coupled plasma emission spectrometry, graphite furnace atomic absorption spectrometry, hydride generation AAS and cold vapour atomic fluorescence as appropriate. In addition, total barium was measured by Flame AAS following alkali fusion to ensure dissolution of all barium sulphate. Particle size analysis and organic matter analyses were undertaken according to generally accepted methodologies: i.e. Dry sieving and pipette and/or particle counter analysis. The data required included both absolute and relative sediment weights by size fraction, together with statistical and graphical summaries of that data. In addition to the particle size data, sample carbonate content (i.e. Loss on acid treatment) and organic matter content (i.e. Loss on high temperature treatment) was reported for each sample. Total organic carbon and nitrogen was determined from a subsample of the particle size sample using a C/N analyser.
