COVID-19 pandemisinin İstanbul'un Şile ilçesinde hava kalitesine (PM10) etkisi

Abstract

Türkiye'deki ilk COVID-19 vakası 11 Mart 2020'de onaylandı. COVID-19 salgınının hızlı yayılma özelliğine bağlı olarak, 21 Mart - 1 Haziran 2020 tarihleri arasında İstanbul genelinde hafta sonları için kısmi kısıtlama uygulamaya konuldu. Sıkı kısıtlama önlemlerinin uygulanması, sosyal davranışları değiştirirken COVID-19 Türkiye Ulusal Sağlık Sistemi üzerindeki etkisini azaltmayı sağladı. Öte yandan, bu zorunlu önlemler insan kaynaklı olayların havat kalitesi üzerindeki etkisini kirlilik seviyelerini kontrol etmeye bağlı olarak belirleme fırsatı sağladı. Bu çalışmanın temel amacı, kısmi kısıtlama önlemlerinin İstanbul'un Şile ilçesi hava kalitesi üzerine etkisini incelemektir. Hava kalitesi analizi, Şile'deki izleme istasyonunun PM10 konsantrasyonu içeren hava kalitesi verileri yardımıyla gerçekleştirildi. Sonuçlar, Şile'nin PM10 konsantrasyonlarında yaklaşık % 16.90 artış olduğunu gösterdi. Bu, COVID-19 salgını sırasında İstanbul'un diğer ilçelerinden göç nedeniyle araç trafiğinin ve insan hareketliliğinin artmasıyla ilişkilendirildi. İlçenin kırsal karakteristik özelliklerinin COVID-19 salgını sırasında İstanbul'un diğer ilçelerinden göç alma sebepleri arasında olduğu değerlendirilmektedir. Bu çalışma, pandemi ile ilgili psikolojik davranış değişikliklerinin ve kısıtlamaların hava kirliliği üzerindeki etkilerini incelemektedir.

The impact of the COVID-19 pandemic on the air quality (PM10) in Şile district of İstanbul, Turkey

Abstract

The first COVID-19 case in Turkey was approved on March 11, 2020. Based on the rapid spread feature of the Covid-19 pandemic, a partial lockdown was put into practice in the whole of İstanbul for weekends from 21st March to 1st June 2020 by the Government. The application of strict restriction precautions enabled to decrease the effect of the Covid-19 pandemic on the Turkey National Health System while changing the social behaviors. On the other hand, these forced measures provided an opportunity to determine the impact of anthropogenic events on air quality based on controlling pollution levels. The main goal of the present study is to examine the effect of the partial lockdown precautions on the pattern of air quality in the Şile district of İstanbul. The analysis of the air quality was carried out with the aid of air quality data of the monitoring station in Şile that contains PM10 concentration. The results showed that an increase of approximately 16.90% in PM10 concentrations of Şile. This was ascribed with the increment of vehicle traffic due to the migration from other districts of İstanbul during the COVID-19 outbreak. This study presents useful supplements to indicate that the application of severe execution of air pollution control plans can heal the air quality.
