Lahoysk, nestled within the Minskaya Voblasts’ region of Belarus, occupies a geographically significant position within the Polesian Lowland. Located at approximately 54.2000° N, 27.8500° E, the city’s terrain is predominantly flat, characteristic of the broader Polesia region, a vast wetland area historically shaped by glacial activity and riverine processes. The surrounding landscape is a mosaic of agricultural fields, deciduous forests, and numerous small lakes and marshes, reflecting the region’s fertile soils and abundant water resources. Lahoysk sits near the Neman River basin, though not directly on the river itself, benefiting from the overall hydrological influence of this major waterway. This proximity to water bodies can, however, exacerbate humidity and contribute to stagnant air conditions under certain meteorological circumstances. The urban–rural gradient around Lahoysk is relatively gradual; agricultural land directly borders the city, and smaller villages are scattered throughout the surrounding area. While not situated within a major industrial belt, the region supports agricultural processing and some light manufacturing, potentially contributing localized pollution sources. The flatness of the terrain, combined with the prevailing wind patterns across the Polesian Lowland, can lead to the accumulation of pollutants, particularly during periods of atmospheric stability. Elevation is minimal, rarely exceeding 150 meters above sea level, further limiting dispersion potential. The surrounding forests, while providing some natural air filtration, can also contribute to particulate matter during the autumn leaf fall season.

Lahoysk’s air quality experiences a distinct seasonal cycle heavily influenced by its continental climate. Spring (March-May) often brings a gradual improvement as temperatures rise and snow cover diminishes, though agricultural activities, including fertilizer application, can introduce localized ammonia emissions. Summer (June-August) generally sees relatively cleaner air, aided by warmer temperatures and more frequent convective mixing, which disperses pollutants. However, periods of intense heat can lead to stagnant air and ozone formation. Autumn (September-November) presents the most challenging period. The combination of cooler temperatures, decreasing daylight hours, and frequent temperature inversions traps pollutants near the ground. Agricultural burning, a traditional practice in the region, also contributes significantly to particulate matter pollution during this time. The falling leaves from the surrounding forests add to the particulate load. Winter (December-February) is characterized by cold, stable air and frequent fog, which severely restricts pollutant dispersion. Temperature inversions are common, leading to prolonged periods of poor air quality. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should limit outdoor activity during these periods, particularly on days with dense fog or calm winds. During the autumn and winter months, it is advisable to avoid strenuous outdoor exercise and to monitor local air quality reports. Maintaining indoor air quality through proper ventilation and air purification can also be beneficial. The prevalence of wood-burning stoves for heating in surrounding rural areas further compounds the winter pollution challenge.
