Niort's air quality benefits from the flat Deux-Sèvres Marais Poitevin wetland plain providing good natural dispersal, with vehicle traffic on the A10 motorway and the surrounding insurance industry headquarters and agri-food operations contributing local sources. Atlantic westerlies from the Bay of Biscay and the Loire Valley generally provide reliable ventilation across the flat Poitou plain, while the surrounding Marais Poitevin wetland landscape provides natural buffering and prevents significant pollution accumulation throughout most of the year.
