摘要：

The temporal trends of the secondary air pollutants NO2 (nitrogen dioxide) and O-3 (ozone) in the urban area of Thessaloniki (Greece) and their spatial distribution are examined statistically. The decreasing trend of primary air pollutants during the decade 1988-97 is not observed in the case of photochemical pollutants (NO2 and O-3) The improvement of fuel quality, the technological innovations in industry and the recent considerable renewal of the vehicle fleet did not Influence similarly the trend of secondary pollutants. The photochemical pollutant temporal evolution in the areas with high traffic shows that the increasing vehicle fleet (mainly the fleet of the new technology passenger cars) is a determinant factor for their levels.
