The COVID-19 pandemic has radically changed many routines in
everyday life, usually in cities. In this period, most of the people
consciously tried to isolate themselves in their homes. With the lockdowns and
restrictions, human activities have significantly decreased. Also, according to
in-situation and satellite observations; it has been found that emissions of
pollutant gases in most countries have decreased significantly because of a
decline in activities forming pollutants such as transportation, mining. In
coronavirus and air pollution-related studies, it is seen that generally large
metropolises or city centers are considered. But, this study focuses on
analyzing air pollution in Trabzon which is a semi-rural city. PM10, PM2.5,
SO2, NO2, and CO, O3 pollutant datasets are taken into consideration as three
periods which represent before (1 Jan-15 March), during (16 March-31 May),
after (1 June-30 June) lockdowns. It is found that during the period of
lockdown, air pollution generally decreased by 20%, while pollutant
concentrations increased by 30% during the normalization period in Trabzon
