Abstract

Sediment samples from multiple sites in the North Sea Coast of England were solvent extracted and analysed by a quadruple gas chromatograph equipped with a mass spectrometer detector in order to determine the concentration and distribution of aliphatic and alicyclic n-alkanes Results indicate that most of the organic. species present in the sediment samples consisted of anthropogenically derived long chain aliphatic and Acyclic n-alkanes (C-n(10-15), (17,) (19-21) (24) (26) (27) (29) (30) (33) (35) (36) (43)). n-alkanols, n-alkanals, n-alkanones. esters as well as many volatile organic compounds (VOCs) Chemical composition of samples and relative concentration were found to vary both spatially and temporally on all scales. These variations are mainly attributable to spatial and temporal variations in source but also parameters such as rainfall, turbulence and micro-organism activity also account for the observed trends (C) 2010 Elsevier Ltd All rights reserved
