EXPERIMENTAL MEASUREMENTS OF C2-C5 AND C6-C10 IN URBAN AREA OF THESSALONIKI, GREECE

The present study refers to experimental ambient air hydrocarbon measurements In the city of Thessaloniki. Greece. during June and July 2006. The measurements were performed at two sites of the Municipal Air Quality Network of Thessaloniki, at the commercial city center (11.4 m asl) and at an urban peripheral site (174.0 m asl). The two locations, city center and peripheral site, have been selected because the), represent the maximum and minimum levels of pollutants measured in Thessaloniki, respectively. The measurements concern two hydrocarbon groups, C2-C5 and C6-C10 and were performed with three automatic gas-chromatographs, selected for their suitability to measure in the field. equipped with FID and PID detectors. The daily and hourly variations of these measurements are presented and a comparison between the two sites is performed. Moreover an additional comparison is made with the permanent measurements of BTEX and of other relevant air pollutants which are performed at the urban area of Thessaloniki.
