Abstract
Concentrations of a range of polycyclic aromatic hydrocarbons (PAH) we re determined by means of coupled gas chromatography-mass spectrometry (GCMS). Water samples were collected, using a contamination-free samp ling device, at two depths (Im subsurface and 3 m above the seabed) at each of the six stations established in the Dover Strait. The station s were occupied during June and October 1990, and July 1991. Concentra tions of PAH were often close to or below the limits of detection for samples of 10.8 1 volume, although a number of samples exhibited high concentrations (of naphthalenes in particular) which were apparently d erived from shipping inputs in the Dover Strait. Future work will requ ire the development of methods with lower limits of detection, and whi ch can integrate concentrations over different timescales in order to obtain time-averaged concentrations of PAH.
