Air pollution levels decrease in Istanbul ‘due to lockdowns’

The rate of air pollution in Istanbul decreased by 10 percent last year compared to 2019, a Turkish academic said.

With many people spending more time at home due to the COVID-19 outbreak, this has brought an improvement in air quality.

Nitrogen dioxide (NO2) emissions, a major air pollutant, has decreased by 10 percent in the Turkish metropolis, according to figures from the Ministry of Environment and Urbanization and the Istanbul Municipality.

Increased air pollution can cause major health risks, said Huseyin Toros, a professor at the Meteorological Engineering Department of the Istanbul Technical University (İTÜ).

Despite the ongoing research and efforts to reduce air pollution on a global scale, "we continue to pollute the atmosphere," Toros said.

Improvement amid pandemic

With the novel coronavirus pandemic, countries across the globe, including Turkey, took measures to curb the outbreak's spread.

Human activity fell dramatically under these precautions, Toros explained, adding that there had been 25 percent less pollution in Istanbul's air during April, May and Novem-ber, when Turkey stepped up measures against the virus, compared to the other months when they were more relaxed.

He said that on weekdays last year, air pollution had decreased by 10 percent on average compared to 2019, with a mean drop of 23 percent during these three months and by 3% during the rest of 2020.

"When we look at the weekends, air pollution decreased overall by 7 percent in 2020 compared to 2019, falling 29 percent on weekends when measures were implemented and rising by 7 percent on weekends when there were no measures," added Toros.
