Assessment of the state of the environment of the Russian Far East
Abstract
Environmental monitoring is a long-term assessment of pollutant levels that helps assess pollution levels and provide information on trends in environmental quality. In addition, the environmental monitoring system supports research by providing scientists with the information they need to conduct long-term studies of the effects of various atmospheric exposures on the population and an overall assessment of the health effects of air pollution. The dynamics and structure of pollutant emissions has changed significantly in recent years. It was revealed that the gross volume of emissions into the atmosphere in 2021 decreased by 0.3% compared to the level of 2015 and amounted to 1592 thousand tons. Emissions from stationary sources in 2021 amounted to 1275.2 thousand tons, increased by 43.7% compared to 2015. The structure of emissions was dominated by CO, the emissions of which amounted to 413 thousand tons (increased by 31.8% since 2015). During the year, there was an increase in emissions of solid substances (by 44%), sulfur dioxide (by 55%), nitrogen oxides (by 56.6%), VOCs (by 77.2%).
