Pollution sources and air quality in the Moscow Region

The paper analyzes the data from Roshydromet air pollution monitoring network in cities of the Moscow region, as well as the official Rosstat data on air pollution emissions from stationary sources and vehicles in Moscow and Moscow region over a 10-year period (since 2007), along with data from Roshydromet soil contamination monitoring network by heavy metals along federal routes in Moscow region for the period 2009–2016. Analysis showed that despite the closure of some industrial plants or moving some of them from Moscow to the Moscow region, the air quality in Moscow remained virtually unchanged for the last 10 years. The high traffic load and the density of the road network have led to the fact that most of the Moscow region has a double excess over the background values of pollutants, especially by heavy metals. The paper also presents trends and spatial variability of air quality in the region under study.
