Priiksky territorial administration of the Ministry of Ecology of the Republic of Tatarstan received a complaint from residents of the Aznakaevsky district. Local residents complained of an unpleasant smell, presumably from a local farm in the village of Aktoba. To assess the state of the air, ecologists from the Priiksky TA together with a mobile environmental laboratory went to the site. Sampling was carried out automatically using special equipment installed on the PEL. Samples were taken at 2 points: near the Racetrack on Druzhby Street and near the Aktoba Megafarm on Bugulminsky Tract street. According to the results of the sample analysis, no exceedances of the maximum permissible concentration of pollutants were detected.
