Аннотация:The article generalizes the data on 1477 snow samples, taken in the areas in the Central Kazakhstan, southeastern West Siberia, and northeastern Altai where Proton launch vehicle stages fell in 2009–2019. In uninhabited territories of the Central Kazakhstan, onto which the propellent falls, snow pollution was reliably established at distances not greater than 10 m from fragments of the first stage. Snow chemistry in the areas where the second stage falls (the southeastern part of West Siberia and the southeastern Altai) reflects the background levels of nitrogen-containing compounds of natural origin and shows no signs of propellent components. Clearly, the areas where either the first or the second stages of Proton launch vehicles fell are not zones of environmental disaster.
