The Impact of Russia-Ukraine geopolitical conflict on the air quality and toxicological properties of ambient PM_2.5 in Milan, Italy.

ABSTRACT: The geopolitical conflict between Russia and Ukraine has disrupted Europe's natural gas supplies, driving up gas prices and leading to a shift towards biomass for residential heating during colder months. This study assessed the consequent air quality and toxicological impacts in Milan, Italy, focusing on fine particulate matter (PM_2.5, d_p < 2.5 μm) emissions. PM_2.5 samples were analyzed for their chemical composition and assessed for their oxidative potential using the dithiothreitol (DTT) assay across three periods reflecting residential heating deployment (RHD): pre-RHD, intra-RHD, and post-RHD periods. During the intra-RHD period, PM_2.5 levels were significantly higher than those in other periods, with concentrations reaching 57.94 ± 7.57 μg/
