Assessment of air pollution in the cities of Perm region

The chemicals emitted from stationary and mobile sources into the air in cities have a harmful effect on the population, contributing to the growth of morbidity and mortality and disturbing the natural environment. In Perm Krai, Russia, industrial facilities discharge about 360 chemicals into the air. The airborne pollution mostly comes from chemical industry, oil and minerals extraction, metallurgical industry, power generation, and transport. This study focused on the assessment of airborne pollution in the cities of Perm Krai. The study used data of the Perm Center for Hydrometeorology and Environmental Monitoring, published in annual environmental reports. It was found that the main pollutant emissions from stationary sources are liquid and gaseous substances. The most common emission components are hydrocarbons coming from pipeline transportation facilities. The second most common substance is carbon monoxide emitted by combustion of various fuels. Gross pollutant emissions tended to increase from 2014 to 2018, with a steady growth of emissions from mobile sources...
