Lgov, situated in the Kurskaya Oblast’ of Russia, occupies a geographically significant position within the Central Russian Upland. Located at approximately 51.67° N, 35.27° E, the town rests on gently undulating terrain, characteristic of the broader region. Its elevation averages around 210 meters (689 feet) above sea level, contributing to localized microclimates and influencing air circulation patterns. The surrounding landscape is predominantly agricultural, a patchwork of fertile fields used for grain and livestock farming, a key economic driver for the Oblast’. To the west, the Desna River flows, providing a natural boundary and a potential source of humidity, though its impact on Lgov’s immediate air quality is moderate. The urban footprint of Lgov itself is relatively compact, a small town with a discernible urban–rural gradient extending outwards into the agricultural lands. While not directly adjacent to major industrial centers, Lgov’s proximity to larger regional hubs, particularly those involved in processing agricultural products and light manufacturing, means it can be affected by transboundary pollution. The prevailing winds, generally from the west, can carry pollutants from these areas. The lack of significant topographic barriers within a 50km radius means that pollutants can disperse relatively easily, but also means that stagnant air conditions, particularly during temperature inversions, can lead to localized air quality degradation. The soil composition, largely chernozem, is conducive to agriculture but can also contribute to dust emissions during dry periods, further impacting air quality.

Lgov’s air quality experiences a distinct seasonal cycle heavily influenced by its continental climate. Winters (December-February) are typically the most challenging period. Cold temperatures frequently lead to temperature inversions, trapping pollutants near the ground and exacerbating existing emissions from residential heating (primarily wood and coal). Fog, common during these months, further reduces atmospheric mixing, intensifying the effect. Spring (March-May) brings a gradual improvement as temperatures rise and winds increase, dispersing pollutants. However, the agricultural activities ramping up during this period, including fertilizer application and tilling, can introduce particulate matter and ammonia into the air. Summer (June-August) generally offers the best air quality, with warmer temperatures promoting atmospheric mixing and frequent rainfall washing away pollutants. However, dry spells can lead to increased dust levels from agricultural fields. Autumn (September-November) sees a return to more variable conditions. As temperatures cool, the risk of temperature inversions increases, and agricultural burning, a traditional practice in the region, can significantly degrade air quality. The months of October and November are particularly susceptible to poor air quality due to a combination of these factors. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should limit outdoor activity during periods of stagnant air or high dust levels, particularly in the winter and autumn. Maintaining indoor air quality through ventilation and air purification can also be beneficial during these times.
