From February 9 to February 16, no excess of permissible concentrations of pollutants in the atmospheric air were recorded by automatic air pollution control stations in Kazan.
Also, according to complaints from residents, sampling trips were organized using a hand-held sampling pump for analysis on a wider list of substances. Sampling was carried out in the residential complex "Salavat Koopere" and at the request of residents in the Moskovsky and Novo-Savinovsky districts. The results of the analyses from the sampling are still in the works.
