ZAGREB, 2 November, 2021 - Zvjezdana Bencetić Klaić of the Zagreb Faculty of Science said on Monday the information earlier in the day that Zagreb was one of the cities with the most polluted air in the world came from the website of a company making air cleaning products.
Speaking on Croatian Television, the professor said the company "publishes all data available to it from the web, regardless of their quality."
Besides using data from state stations which monitor air quality, she said, the website also uses some unusual sources such as Tobacco Travno.
At this time of year emissions of pollutants are higher due to heating and weather conditions, such as fog and lack of wind, which favour higher concentrations, but the next rain and stronger wind cleanse the atmosphere, she said.
She added that it was not only important what the concentration was at any given hour but over a longer period of time as well.
