A field study was carried out to investigate whether polyaromatic hydrocarbon (PAH) contamination in shore crabs (Carcinus maenas) could be measured using fluorescence spectrometry. Crabs were collected as part of an integrated study to assess PAH contamination in Southampton Water, UK. Urine was collected from crabs via a non-destructive technique and analysed using fixed wavelength fluorescence (FF) and synchronous fluorescence spectrophotometry (SFS) in order to determine the presence of PAH metabolites, indicative of PAH exposure. By scanning at wavelength pairs specific to a variety of PAH groups the fluorescence of metabolites was analysed and attributed to the following PAH groups; naphthalenes, pyrenes and benzo[a]pyrene (BAP). Naphthalene-type, pyrene-type and BAP-type metabolites were detected using FF and SFS techniques and two distinct parameters were measured; Peak Intensity and Peak Area. Results showed that crabs obtained near a petroleum refinery, a point source of PAH discharge, exhibited significantly higher PAH metabolites for all PAH groups, than at sites sampled along the estuary (ANOVA, p < 0.05). This study highlights the effectiveness of using FF and SFS as a rapid and cost-effective biomonitoring tool for detecting PAH contamination. (C) 2004 Published by Elsevier Ltd.
