5.2- Average Concentrations of PM10 and SO2 in Ambient Air

Pollutant concentration in ambient air is a major state indicator regarding air pollution. Hence, air quality is continuously monitored in all 81 provinces by the monitoring stations operated within “National Air Quality Monitoring Network”. Data provided by these monitoring stations are publicly available online at: www.havaizleme.gov.tr .

According to the information provided by the National Air Quality Monitoring Network, the stations with highest 10 validated annual average PM10 and SO2 measurements are presented in Table 13. Edirne (Keşan) has had the highest annual SO2 average for the last 3 years. In terms of annual average PM10 value, the station in Iğdır has been within the top 3 stations during the last 3 years.

Regarding the top 10 stations with the highest annual average PM10 during the last 5 years between 2012-2016, Siirt station has been among top 10 for 5 times, while Kayseri (Hürriyet) and Düzce stations 4 times, Iğdır, Bursa and Manisa stations 3 times. For SO2,  Yozgat and Tekirdag stations have been among the 10 stations with the highest annual SO2 averages in the last five years for 4 times, Canakkale (Can), Edirne (Kesan), Afyonkarahisar and Karabuk stations have been for 3 times in the top10 list.

2016 yearly average PM10 concentrations are laid down in the graph 24 above. For 51% of the air quality monitoring stations (for which the values were provided and incorporated), average values exceeded the national limit value for 2016, which is 52 μg/m3. 78% of the stations experienced values higher than the European Union limit value, while in 97% of the stations, World Health Organization air quality guideline was exceeded.

Within the scope of "Clean Air Action Plans" in order to improve air quality in the provinces; it is necessary to increase the effectiveness of mitigation measures such as: application of best available techniques and best environmental practices in the industrial installations, control of fuel types used for domestic heating, improve combustion systems, thermal insulation of the buildings, stoker training and measures to abate pollution from motor vehicles.
