Pilsen, on the Bohemian plain where four rivers meet, sees industrial emissions and vehicle traffic across the plain as its principal air quality driver. The Plzeň Region terrain shapes local dispersion, and while breezy, unsettled weather usually brings swift improvement, prolonged calm periods can let pollutant levels climb noticeably.
