Extreme smog levels continue – free public transport in Kraków 

Due to persistent smog in Kraków, public transport is free of charge for the third day in a row. On Monday, measuring stations registered PM10 levels above 300 micrograms per cubic meter. The acceptable standard is 50 micrograms per cubic meter. Monday (January 30) is the 10th day of this month, when - because of smog - drivers could travel on public transport for free. "If, in the following hours during the day, the air quality does not improve and the level of PM10 exceeds 150 micrograms per cubic meter, transport will also be free tomorrow," Jan Machowski from the press Office of the City of Kraków (UMK) told the Polish Press Agency (PAP). High levels of smog have been recorded in several cities across Poland in recent weeks. During such periods, authorities advise children and young people, the elderly, pregnant women, and people suffering from respiratory diseases to avoid spending too much time outside and limiting physical exertion.
