Assessment of pollutants discharges and air pollution in the Tyumen region (without considering autonomous districts) and its urban districts

Abstract

The article provides an analysis of pollutants discharges in the Tyumen region, in the Tyumen region without considering autonomous districts, and in its urban districts for the period of 2013-2017. The researcher compares the number of stationary emission sources throughout the Tyumen region in 2017 and in 2013. The increasing amount of pollutants discharges has also been ranged from the Tyumen region (129083 tons) to its urban districts, namely Tyumen (16890 tons), Tobolsk (13723 tons). The decrease in emissions was noted in Ishim and Yalutorovsk in 2017 compared to 2013. It has been determined that the total amount of discharges in urban areas contained the average portion of solid discharge up to 5.0%, and of gaseous and liquid discharges up to 95.0%. Carbon monoxide and hydrocarbons (without VOCs) prevailed among gaseous emissions in the Tyumen region without considering autonomous districts (29.1 and 26.1% of all gaseous emissions respectively). Testing revealed the increase in the number of trapped and neutralized pollutants in the Tyumen region without considering autonomous districts and including urban districts in 2017 compared to 2013. In the analyzed period, the atmosphere in Tyumen and Tobolsk was characterized as slightly polluted.
