Iași's air quality faces winter challenges from residential wood and coal burning generating elevated PM2.5 alongside vehicle traffic on the A8 and surrounding road network in this major northeastern Romanian university city. The surrounding Moldavian plateau ridgelines create modest topographic variation, while continental easterly airflows from the Ukrainian steppe can carry additional regional agricultural burning emissions during dry autumn periods.
