The fluorimetric analysis of the content of formaldehyde, volatile phenols and oil has been performed in the samples of
atmospheric precipitation. Atmospheric precipitation (rain and snow) were collected in Barnaul from October 2013 until September 2018. The average concentration of oil in atmospheric precipitation was 0.07 ppm, volatile phenols – 0.006 ppm and
formaldehyde – 0.1 ppm. A seasonal increase of the oil concentration was revealed in the cold period of the year. For formaldehyde
a seasonal increase of the concentration has been revealed in the warm period of the year. Volatile phenols are characterized by
a constant emission into the atmosphere of the Barnaul regardless of the time of year. The anthropogenic load of the formaldehyde, volatile phenols and oil on surface waters within the boundaries of the city of Barnaul was calculated taking into account
average rivers’ discharge. Full-flowing the Ob River does not experience significant anthropogenic load within the boundaries
of the city of Barnaul, as regards of the studied pollutants. Its waters are able to dilute the concentration of incoming studied
organic pollutants from urban stormwater runoff to before MAC. For the Barnaulka River, the stormwater runoff within the
boundaries of the city of Barnaul is a serious source of pollution with oil and volatile phenols. Phenolic compounds pose especially high risk of pollution of the Barnaulka River. Contamination of the Barnaulka River with formaldehyde is not observed.
For the improvement current unfavorable environmental situation, it will be necessary to construct the urban treatment plants.
