Abstract

The extensive reconstruction process initiated in Kahramanmaraş following the February 6, 2023 earthquakes poses a significant pressure on urban air quality. This study examines the spatial distribution of PM2.5, NO₂, and O₃ pollutants across ten neighborhoods in the city's two central districts over a 30-day period during this unique phase. Hourly data obtained from the Google Air Quality API were compared with World Health Organization (WHO) guideline values. The findings reveal sharp inter-neighborhood variations in PM2.5 concentrations, suggesting that elevated levels in certain areas may be linked to reconstruction activities. In contrast, ozone (O₃) pollution was identified as a widespread issue across the entire region, irrespective of neighborhood, while NO₂ levels remained below the limits. These results indicate that to protect public health during post-disaster urban recovery, continuous, localized air quality monitoring strategies that consider the unique dynamics of each pollutant are vital. This research offers a significant perspective on the atmospheric impacts of large-scale reconstruction processes.

Özet

6 Şubat 2023 depremleri sonrası Kahramanmaraş'ta başlayan yoğun yeniden inşa süreci, kentsel hava kalitesi üzerinde önemli bir baskı oluşturmaktadır. Bu çalışma, bu olağanüstü dönemde şehrin iki merkez ilçesindeki toplam on mahallede PM2.5, NO₂ ve O₃ kirleticilerinin mekânsal dağılımını 30 günlük bir periyotta incelemektedir. Google Air Quality API'sinden elde edilen saatlik veriler, Dünya Sağlık Örgütü (DSÖ/WHO) kılavuz değerleriyle karşılaştırılmıştır. Bulgular, PM2.5 konsantrasyonlarının mahalleler arasında keskin farklılıklar gösterdiğini ve bazı mahallelerdeki yüksek seviyelerin yeniden inşa faaliyetleriyle ilişkili olabileceğini ortaya koymuştur. Buna karşın Ozon (O₃) kirliliğinin, mahalle ayrımı gözetmeksizin bölge genelinde yaygın bir sorun olduğu, NO₂ seviyelerinin ise limitlerin altında kaldığı saptanmıştır. Bu sonuçlar, afet sonrası kentsel iyileştirme süreçlerinde halk sağlığının korunması için her kirleticinin kendine özgü dinamiğini dikkate alan, yerel ölçekli ve sürekli hava kalitesi izleme stratejilerinin hayati önem taşıdığını göstermektedir. Bu çalışma, büyük ölçekli yeniden yapılanma süreçlerinin atmosferik etkilerine dair önemli bir bakış açısı sunmaktadır.
