Özet

The focus of this paper is to evaluate the air quality change of Kayseri Province during the Covid-19 outbreak and examine the possible climate change impact. Air quality were evaluated using PM10, SO2, air temperature, and natural gas consumption data for 56-day quarantine period in Kayseri. Analysis of variance (ANOVA) applied to all data set and then the Tukey-Kramer procedure implemented. CO2 equivalent calculated with EPA (United States Environmental Protection Agency) formulas. The PM10 concentration of 2020 decreased by 40% and 9% in the city center and organized industrial zone (OIZ), respectively compared to 2019. As for SO2, 34% and 30% decreased was seen for the city center and OIZ, respectively. CO2 emission from transportation and natural gas decreased by 5.5 times and 16% than normal periods, respectively. Total reducing CO2 emission during 56-day pandemic period was almost 1 million ton.
