Effect of Meteorological to Urban Air Pollutants: The Case of Konya

Gülnihal KARA

Abstract


The atmospheric concentrations of several atmospheric pollutants: SO2 , PM10, and
meteorological parameters have been measured at several locations in Konya city, Turkey since 1990.
The objective of this work is to estimate the effects of meteorological factors on the air quality levels for
this city. The measurements are achieved using 4 fixed stations and 1 mobile station to cover several
important areas of Konya. The relationship of pollutants concentrations to five major meteorological
parameters is assessed, with a particular focus on the meteorological conditions that create high-pollution episodes.
The results showed that, wind speed, relative humidity and temperature were found to have an
influence not only on pollutant concentrations but also on the correlation between pollutants. At higher
wind speeds, from the surrounding area was entrained by the wind, thus contributing to ambient
particulate matter levels. For SO2 and PM10 the highest average concentrations occurred at humidity
above 75-80%, atmospheric pressure above 890-910 hpa and lower wind powers than 1.2 m/s during
winter period.
