Polycyclic aromatic hydrocarbons in sewage, mussels and tap water

Polycyclic aromatic hydrocarbons (PAH) have been determined in sewage discharge, mussels and tap water by glass capillary gas chromatography. Up to 30 PAH compounds have been identified. The concentration levels are low, respectively 0.8 – 7.7μg/1, 0.5–1.1 μg/g and 0.002 – 0.2μg/1 of sum PAH have been determined in sewage discharge, mussels and tap water. The accumulation rate in mussels seems to be rather slow at the ambient water concentrations.
