Hradec Králové's air quality reflects the flat Elbe-Orlice river confluence basin in eastern Bohemia, with vehicle traffic on the D11 motorway and surrounding manufacturing and pharmaceutical industry contributing local sources. Winter residential wood and coal burning generates elevated PM2.5, while the flat Bohemian plain generally allows reasonable wind dispersal on most days and the surrounding Eastern Bohemian hills create modest topographic variation throughout the year.
