Water, air and noise. What environmental pollution is found in St. Petersburg – the project “To be precise” found out

The authors of the project “To be precise” published a study on the main environmental problems that affect the life and health of Russians. “Paper” contacted the author of the text, Vladimir Omelin, and learned about environmental pollution in St. Petersburg.

Water problems. 100% of St. Petersburg residents are provided with drinking water supply – this is the best indicator in the country. However, in half of the districts of the city, an excess of iron in tap water was recorded. These are Vyborgsky, Kalininsky, Kirovsky, Krasnogvardeisky, Krasnoselsky, Kurortny, Petrogradsky, Petrodvortsovy and Primorsky districts.

In 2021, a high level of pollution was also found in St. Petersburg water bodies. As the authors of To Be Exact found out, 100% of the sea water in the city is poisoned by pollutants. Omelin confirmed “Paper”that the reservoirs of St. Petersburg, which are not used for household and drinking purposes, are among the dirtiest in the country.

In addition, one of the highest volumes of polluted wastewater discharges among other regions was found in St. Petersburg – 8.5% of all polluted wastewater in the Russian Federation.

Air problems. Petersburg is gradually reducing the level of air pollution, said the author of the study “To be precise.” Thus, the concentration of ammonia gases fell, but the proportion of ozone in the atmosphere increased. A high level of this gas in the air causes irritation of the mucous membranes of the eyes, nose, throat, headache, at very high concentrations, coughing, dizziness, and a sharp decline in cardiac activity are observed.

Compared to other regions, the level of air pollution in the city remains low, Omelin added.

Other environmental issues. According to 2021 data, the noise level in St. Petersburg does not meet hygienic standards. In St. Petersburg, the share of noise measurements was 74.5%, which is one of the highest figures among other regions.

According to the author of the study “To be precise”, noise pollution may be associated with the urbanization of St. Petersburg. However, Omelin also drew attention to the fact that another Russian metropolis – Moscow – was not included in the list of noisy regions.

Impact on other regions. There are five facilities in St. Petersburg with a high level of negative environmental impact on the environment. The largest of them is the former hydraulic ash dump of CHPP-17 (New Devyatkino). It has a negative impact on the territory where more than 136 thousand people live.

The list of environmentally hazardous sites also includes former or existing landfills in Komarov, Zelenogorsk, Primorsky and Nevsky districts. In total, they pose a health hazard to 100,000 people.
