From May 18 to 24, automatic air pollution control stations in Kazan recorded exceedances of the maximum permissible concentrations of pollutants:
AAPCS-1 (Osinovo village, Zelenodolsky dist.), exceeding the permissible content of hydrogen sulfide was recorded;
AAPCS-3 (Kazan, 76 Maksimova str.) exceedances in hydrogen sulfide and formaldehyde were recorded;
AAPCS-5 (Kazan, I. Shakirov st, 3) excess hydrogen sulfide was recorded.
No excess pollutants were recorded at the other AAPCS located in Kazan.
Additionally, we inform you that the chromatograph for measuring phenol at AAPCS-4 (Kazan, 26 Chetaeva str.) has been undergoing diagnostics at a service organization since May 16.
The gas analyzer for the determination of nitrogen dioxide at AAPCS-5 (Kazan, Shakirov str. 3) is under annual verification
With this in mind, data on phenol at AAPCS-4 and nitrogen dioxide at AAPCS-5 are temporarily not displayed on the Ecological Map of the Republic of Tatarstan.
