No excess pollutants were recorded at the other AAPCSs located in Kazan.
Additionally, we inform you that the chromatograph for measuring phenol at AAPCS-4 (Kazan, 26 Chetaev str.) has been undergoing diagnostics and repair 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.
