Shpola, nestled in the heart of Ukraine’s Cherkaska Oblast, occupies a gently undulating landscape within the Dnieper Lowland. Situated at coordinates 48.9997, 31.3922, the city’s terrain is characterised by rolling plains intersected by small river valleys and ravines, typical of the region. The landscape surrounding Shpola is predominantly agricultural, dominated by fertile black soil (chernozem) used extensively for crop cultivation, particularly grains and sunflowers. The city itself is bisected by the small Supiy River, a tributary of the Ros’ River, which influences local microclimates and potentially contributes to humidity levels. While not directly within a major industrial belt, Shpola’s proximity to larger regional centres with industrial activity means it can experience some degree of long-range pollutant transport. The urban-rural gradient is relatively sharp; the city’s core gives way quickly to expansive agricultural fields. This proximity to agricultural land impacts air quality through seasonal burning of crop residue and the use of fertilizers. The prevailing winds, generally from the west, can carry pollutants from these sources into and through the city, affecting air quality concentrations. The relatively flat terrain limits natural dispersion of pollutants, potentially exacerbating localised pollution events.

Shpola’s air quality follows a distinct seasonal pattern. Spring (March-May) often sees a temporary worsening due to agricultural practices – the burning of stubble after winter and the application of nitrogen-based fertilizers release particulate matter and ammonia. Winds can be variable during this period, sometimes trapping pollutants. Summer (June-August) generally offers the cleanest air, benefiting from higher temperatures promoting dispersion and rainfall washing away pollutants. However, prolonged heatwaves can lead to localised ozone formation. Autumn (September-November) brings a return of agricultural burning, combined with the onset of temperature inversions, where a layer of warm air traps cooler, polluted air near the ground. This is often the period of poorest air quality. Winter (December-February) sees reduced agricultural activity, but heating from coal and wood-burning stoves becomes a significant source of particulate matter, especially during calm, cold periods. Fog is common, further reducing visibility and trapping pollutants. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during autumn and winter. Spring can also pose risks due to allergen levels and particulate matter. Monitoring wind direction and avoiding activity near agricultural fields during burning periods is advisable.
