Dolynska, nestled within the Kirovohradska Oblast of central Ukraine, occupies a geographically significant position within the broader Dnipro River basin. Located at approximately 48.1111° N, 32.7647° E, the city sits on a gently undulating plain, characteristic of the Central Ukrainian Upland, with an elevation averaging around 120 meters above sea level. This relatively low elevation, combined with the surrounding flat terrain, can contribute to the stagnation of air pollutants, particularly during periods of calm weather. Dolynska is surrounded by a predominantly agricultural landscape, with extensive fields of wheat, barley, and sunflowers dominating the rural areas. To the north and east, the land gradually rises, transitioning into more varied terrain. While not directly adjacent to a major river, the proximity to the Southern Bug River, approximately 50km to the southwest, influences regional weather patterns and can impact the dispersion of airborne particles. The urban–rural gradient around Dolynska is relatively sharp; the city’s footprint is clearly defined, bordered by agricultural land, minimizing the buffering effect of extensive green spaces. Historically, the region has seen limited heavy industry, but agricultural practices, including fertilizer use and occasional field burning (though increasingly regulated), can contribute to localized air quality concerns. The city’s location within a temperate continental climate zone means it experiences distinct seasonal variations, which significantly impact air quality dynamics.

Dolynska’s air quality follows a distinct seasonal pattern dictated by its temperate continental climate. Spring (March-May) often brings a noticeable increase in particulate matter due to agricultural activities – soil dust from plowing and, though less common now, the lingering effects of controlled burns. The warming temperatures and increased sunlight can also lead to higher levels of ground-level ozone formation, particularly during sunny, calm days. Summer (June-August) typically sees improved air quality due to increased convective mixing – warmer air rising and dispersing pollutants. However, periods of intense heat can exacerbate ozone issues. Autumn (September-November) presents a complex picture. While cooler temperatures generally reduce ozone formation, the harvesting season and associated agricultural practices can again elevate particulate matter. Fog, common in autumn mornings, traps pollutants close to the ground, creating localized air quality challenges. Winter (December-February) often brings the most concerning air quality conditions. Temperature inversions, where a layer of warm air sits above cooler air near the ground, prevent vertical mixing, trapping pollutants. Cold, still air and frequent fog further exacerbate this effect. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should limit outdoor exertion during these periods. During the warmer months, particularly July and August, limiting strenuous activity during peak ozone hours (typically midday) is advisable. Spring and autumn require vigilance regarding particulate matter, especially on days with agricultural activity or persistent fog. Maintaining indoor air quality through ventilation and air purification can offer some protection.
