THE OCCURRENCE OF PRIORITY PAHs, NONYLPHENOL AND OCTYLPHENOL IN INLAND AND COASTAL WATERS IN ATHENS AND MYTILENE, GREECE

The present work regards the investigation of the occurrence of the seven priority PAHs, NP and OP in surface waters in Athens and Mytilene, Greece. Samples were collected and analyzed seasonally for one year from the four reservoirs supplying water to the drinking water treatment plants of Athens: Mornos, Marathonas, Yliki and Evinos. Samples were also collected from inland waters of Mytilene island (rivers Mylopotamos and Evergetoulas), and from coastal waters in Mytilene area (five sampling points). The determination of PAHs, NP and OP was conducted by means of gas chromatography-mass spectrometry (GC-MS) method. The results have shown that in most cases the waters studied are free from PAHs, possibly because of lack of PAHs release sources nearby the particular areas, or due to the adsorption of PAHs on sediments. NP occurred at low levels in several cases, while OP was detected only in one sample.
