Özet:

 In this study, the changes in particulate matter PM10 levels in dowtown Balıkesir, located in the south of the Marmara region, were examined with statistical and spatial analyzes between 2019 and 2021 of the the pandemic period. As a result of the analysis of PM10 and meteorological parameters that were continuously measured in Balıkesir, the year of 2021 which coincides with the middle of the pandemic period, has beed recorded as the time period with the highest PM10 levels were observed. Especially, the number of days that exceeded the legal limit in 2020 and 2021 were reported as three-digit numbers throughout the years. As a result of concentration-weighted trajectory CWT analysis, North African desert dust rather than local sources that were more effective for Balıkesir downtown when the highest daily PM10 level was measured on January 21st, 2021. As a result of the cluster analysis, it was determined that the high concentration PM10 levels measured, as in the CWT analyzes, were influenced by continental transport rather than local sources, especially the desert dusts coming from the desert regions of North Africa over the Mediterranean Sea. In addition, as a result of the cluster analysis, it has been determined that there are transports from Eastern Europe, especially in the southeastern part of Bulgaria, from places where coal-fired thermal power plants are densely located.

 Bu çalışmada, Balıkesir kent merkezinde partikül madde PM10 seviyelerinin pandemi dönemini kapsayan 2019 ile 2021 yılları arasında değişimleri istatiksel ve mekânsal olarak analiz edilmiştir. Sürekli ölçülen PM10 ve meteorolojik parametrelerin analizleri sonucunda pandemi dönemine denk gelen 2021 yılı PM10 seviyelerinin en yüksek olduğu zaman dilimi olarak kayıtlara geçmiştir. Özellikle, 2020 ve 2021 yıllarında yasal limit aşımı gözlemlenen gün sayıları yıl içerisinde üç basamaklı sayılar seviyesinde ifade edilmiştir. Konsantrasyon ağırlıklı yörünge CWT analizi sonucunda, en yüksek günlük PM10 seviyesinin ölçüldüğü gün olan 21.Ocak.2021 tarihinde Balıkesir il merkezi için etkili olan kaynakların lokal kaynaklardan çok Kuzey Afrika çöl tozlarının etkisinde kıtasal taşınımların olduğu tespit edilmiştir. Küme analizleri sonucunda ise, ölçülen yüksek konsantrasyonlu PM10 seviyelerinin lokal kaynaklardan çok kıtasal taşınımların rol oynadığı özellikle Akdeniz üzerinden Kuzey Afrika çöl bölgelerinden gelen çöl tozlarının etkili olduğu tespit edilmiştir. Ayrıca, yine küme analizleri sonucunda, küçümsenemeyecek oranda Doğu Avrupa üzerinden de özelikle Bulgaristanın güney doğu bölümünde kömür yakmalı termik santrallerin yoğun olarak bulunduğu yerlerden taşınımların olduğu da düşünülmektedir.
