Pelahiivka, nestled within the Donetska Oblast of eastern Ukraine, occupies a geographically significant position within the broader Donbas region. Located at approximately 48.0989° N, 38.6128° E, the town sits on a gently undulating plain, characteristic of the Azov Upland, with an elevation averaging around 180 meters above sea level. This relatively low elevation, combined with the surrounding flat terrain, contributes to a tendency for air pollutants to accumulate, particularly during periods of stable atmospheric conditions. The landscape surrounding Pelahiivka is a mosaic of agricultural fields – predominantly wheat and sunflower – interspersed with pockets of deciduous and coniferous forest. To the west, the terrain gradually rises, offering some limited ventilation. While not directly adjacent to a major river, the town draws water from smaller tributaries feeding into the Donets River basin, influencing local humidity and potentially impacting particulate matter deposition. Historically, the Donbas region has been a major industrial hub, with coal mining and heavy industry dominating the landscape. Although Pelahiivka itself is a smaller settlement, its proximity to larger industrial centers like Pokrovsk and Kurakhove means it is susceptible to transboundary pollution. The urban-rural gradient around Pelahiivka is relatively gradual, with agricultural land extending outwards, creating a mixed landscape that influences both local climate and air quality patterns. The soil composition, largely chernozem, also impacts dust generation during agricultural activities, further contributing to particulate matter in the air.

Pelahiivka’s air quality experiences a distinct seasonal cycle heavily influenced by meteorological conditions and regional activities. Spring (March-May) often brings a noticeable increase in particulate matter due to agricultural practices like plowing and fertilizer application, combined with increased wind speeds stirring up dust from exposed fields. The transition from cold to warmer temperatures can also lead to increased biomass burning as farmers clear land. Summer (June-August) generally sees improved air quality, with higher temperatures promoting atmospheric mixing and dispersing pollutants. However, periods of intense heat can lead to stagnant air and ozone formation. Autumn (September-November) presents a complex picture. While cooler temperatures can reduce ozone levels, the harvest season brings renewed agricultural emissions, and the onset of fog, common in this region, traps pollutants near the ground, creating localized episodes of poor air quality. Winter (December-February) is typically the most challenging period. Cold, stable air masses frequently lead to temperature inversions, where a layer of warm air sits above cooler air, preventing vertical mixing and trapping pollutants close to the surface. This, coupled with reduced sunlight hours and potential for domestic heating using coal or wood, results in elevated levels of particulate matter and other pollutants. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should limit outdoor activity during periods of fog and temperature inversions, particularly in the winter months. Avoiding strenuous activity during peak pollution episodes is also advisable. Public health advisories, when issued, should be strictly followed to minimize exposure.
