Assessment of pollutants emissions into the atmosphere due to the fire at the Kalynivka oil depotcaused by a missile strike in March 2022

The study assessed the scale of atmospheric pollution as a result of the fire at the Ka-lynivka oil depot in March 2022 due to missile shelling, which led to the burning of 6124.6 tons of gasoline and diesel fuel. Using an approved method, the volumes of pollutants emitted into the atmosphere due to the fire were calculated, namely: CO2 (14.3 tons), particulate matter PM2.5, PM10 and soot (27.4 tons), NOₓ (5.8 tons), SO2 (0.05 ton) and also H2O (6.5 tons), etc. Burning truck tires additionally caused emissions of polycyclic aromatic hydrocarbons, metalcompounds, and other toxic substances. Extinguishing the fire using fluorinated foam (AFFF, AFFF AR) caused additional emissions of fluorinated surfactants. The fire extinguishing area was about 1.4 hectares, and the volume of foam used was 12—15 thousand liters. The discharged substances pose serious risks to ecosystems, including toxicity, climate impacts, and threats to human health.
