Extreme Surface Ozone Concentrations in the Kirov Region of the Russian Federation during Summer Heat Waves of 2010 and 2016 | Chapter 4 | Modern Advances in Geography, Environment and Earth Sciences Vol. 7

The goal of this study was to compare peak values of surface ozone content recorded at the Vyatskiye Polyany monitoring station during summer heat waves in 2010 and 2016, when wavy and abnormally high air temperatures were seen for an extended period of time. The results of the data analysis from the continuous monitoring system are given. The maximal short-term (peak) recorded values were evaluated at 20-minute, 1-hour, and 8-hour average times. The amplitudes and durations of peak ozone concentrations in 2016 greatly exceeded those seen in 2010 under similar temperature conditions. An rise in the quantity of ozone precursors in the region's atmosphere could be one of the possible causes of this variation.

Estimation of Ground-level Ozone as a Risk Factor for Crop Production in Central Regions of the Russian Federation | Chapter 3 | Modern Advances in Geography, Environment and Earth Sciences Vol. 7

In the territory of central Russia, surface ozone is considered a risk factor for crop productivity. The known processes of ozone's effect on plants are discussed, as well as the quantities of ozone in the surface atmosphere that are harmful to various plant groups. The results of long-term ground-level ozone monitoring in central Russia (Vyatskiye Polyany town) show that, as a result of ongoing climate change and increased atmospheric pollution with nitrogen oxides, volatile hydrocarbons, and carbon monoxide, even in central Russia's moderate non-hot climate, the ozone content of the surface atmosphere has increased significantly. Furthermore, the doses of ground-level ozone that plants in central Russia can be exposed to are comparable to and even surpass the amounts considered safe. This study examines the mechanics of ozone's impact on plants, the levels of ozone in the surface atmosphere that are harmful to different plant families, and monitoring data on tropospheric ozone in Russia's central regions.
