Nikolaeva Natalia Sergeevna

The research conducted an assessment of snow in one of its storage sites in Tyumen. 5 snow samples were analyzed. As a control option, clean, recently fallen surface snow was used. The following parameters were determined in the snow samples: pH, iron, cadmium, calcium, magnesium, sodium, petroleum products, nitrite ion, sulfate ion, chloride ion and total mineralization. According to the results of the studies, the excess over the MPCr.x. in sodium (3.8-9.6 times), in petroleum products (1.8-2.1 times), in chlorides (1.4-7.75 times), in mineralization (1.8-4.17 times) were revealed. The salt composition of halite qualitatively and quantitatively coincides with the salt composition of snow taken from its storage site in Tyumen.
