Water quality in the snow cover of the city of Tyumen

Nikolaeva Natalia Sergeevna  (postgraduate student, Tyumen Industrial University, Tyumen)

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.

Keywords:snow, halite, sodium, chloride ion, sulfate ion, technical salt, landfill.
