Ostrowiec Świętokrzyski's air quality faces significant challenges from the Celsa Ostrowiec steelworks, one of Poland's remaining integrated steel plants generating elevated PM2.5, SO₂, and heavy metals alongside vehicle traffic on the DK9 national road. The surrounding Świętokrzyskie ridgelines create topographic variation, while winter residential coal burning and the steel plant's industrial emissions compound the seasonal air quality challenge in this central Polish industrial city.
