Caltanissetta's air quality reflects the enclosed central Sicilian plateau at 588 metres, with vehicle traffic on the A19 motorway and surrounding sulphur mining legacy and agricultural operations contributing local sources. The surrounding Sicilian mountains create partial topographic enclosure, while the Mediterranean climate's summer anticyclonic conditions allow ozone to accumulate from vehicle emissions and Saharan dust intrusions periodically deliver elevated PM10 across the central Sicilian interior throughout the year.
