An annual “smog ranking” has found that Poland’s air – which is among the most polluted in Europe – has improved significantly. The average annual concentration of one type of harmful air-borne particles was within maximum safe limits in all monitored places for the first time since 2015.

“These are good signs from a still-smoggy Poland,” says Piotr Siergiej, spokesman of Polish Smog Alarm, the NGO that produced the annual report, which is based on 2022 data from the Chief Inspectorate of Environmental Protection (GIOŚ).

Smog Alarm’s ranking takes account of three categories: annual average concentration of benzo(a)pyrene (BaP) and small particulates known as PM10s – both of which have adverse health effects – and the number of days in the year during which air pollution levels exceed official safety limits.

Regarding PM10s, the maximum safe limit for their annual average concentrations is 40 micrograms/m3. The place in Poland with the highest figure was Nowa Ruda – a small town in Lower Silesia that also topped last year’s ranking – where the annual average concentration reached 38 micrograms/m3.

That marked a decrease of 47% over the last nine years. Similar falls were recorded in other cities that have some of Poland’s worst air, with Kraków and Rybnik seeing PM10 levels decrease by 40% over that period.

When it comes to the number of smoggy days, among the worst ten places the average figure in the latest ranking was 63.2, which represents a 22% decline from last year’s average of 80.9.

Siergiej pointed to the declining use of coal heating stoves – known colloquially in Polish as kopciuchy – as a factor. Last year, over 35% of Polish households were estimated to use coal for heating, and this has long been seen as a primary cause of Poland’s air pollution.

However, since 2018 the government’s “Clear Air” programme has sought to help households replace old heaters with more modern, cleaner alternatives, as well as to improve insulation. Some places, including Kraków and Warsaw, Poland’s two largest cities, have also moved to ban the use of coal in heating.

“We can see that the implemented actions, especially the elimination of kopciuchy, are starting to bring results,” said Siergiej. “However, it is extremely important that government and local government authorities do not rest on their laurels and continue these activities.”

He noted that in Nowa Ruda, the concentration of carcinogenic benzo(a)pyrene is still 900% of the permissible level, while in many other places – such as Nowy Targ, Nowy Sącz, Wadowice, Rynik and Żywiec – it is 600% or 700% of permitted safe levels.

Polish Smog Alarm also warns that many towns famous for their “sanatoriums” – places where people, especially the elderly, are sent to recover their health – have harmful air. Szczawnica, Szczawno-Zdrój, Rabka-Zdrój and Jedlina-Zdrój all had BaP levels of 300% to 600% of the safe limit.

“The air is slowly improving and the number of deaths caused by pollution is also decreasing, but the situation is still very bad,” said Smog Alarm’s spokesman. “The continuation and even acceleration of anti-smog measures is key to improving air quality in our country”.

Air pollution is estimated to cause 50,000 premature deaths annually in Poland, as well as a range of other health problems.
