Spatial and temporal distribution of inorganic and organic pollutant concentrations at Northwestern Anatolia

Sarısaltık, Ufuk
Concentrations of inorganic pollutants including NO2, SO2, O3 and organic pollutants including benzene, toluene, ethylbenzene, o-xylene and m&p-xylene, which are known as BTEX compounds were measured on a seasonal basis in 13 cities located in the Central and Northern parts of Anatolian Plateau. Cities included in measurements were Ankara, Bartın, Bolu, Çankırı, Düzce, Eskişehir, Karabük, Kastamonu, Kırıkkale, Kırşehir, Kütahya, Yozgat, and Zonguldak. Sampling was performed in four seasonal campaigns in each city between July 2014 and June 2015 by using passive VOC and inorganic samplers prepared in METU. Sampling and analysis of collected samples were completed. In this work, data generated in the above mentioned campaigns were statistically evaluated to understand how BTEX and conventional inorganic pollutants concentrations are related to demographic conditions at central Anatolian Plateau. Since each pollutant was measured in more than one location in each city, urban averages were established as the first step. How pollutant concentrations vary between residential, traffic-impacted and industrial parts of the cities were evaluated. Variation in concentrations of organic and inorganic pollutants between cities were evaluated related to demographic differences, such as differences in population, traffic intensity. To measure the air pollution in these cities, new station locations and numbers were determined and suggested according to regulation on Air Quality Assessment and Management to protect human health by the ArcGIS software program by using Inverse Distance Weighted (IDW) interpolation method.
