Beyləqan, nestled within the Beyləqan Rayon of Azerbaijan, occupies a significant position in the country’s central lowlands. Situated at coordinates 39.7692°N, 47.6156°E, the city’s terrain is largely flat, characteristic of the Kura-Araz Lowland. This region is defined by the Kura River, which flows nearby, influencing local humidity and potentially contributing to fog formation during cooler months. The surrounding landscape is predominantly agricultural, with extensive cotton and grain fields dominating the area. Beyləqan’s location isn’t directly within a major industrial belt, but its proximity to agricultural processing facilities and transportation routes connecting regions contributes to localised emissions. The urban-rural gradient is quite sharp; the city itself is relatively compact with a population of around 12,263, quickly transitioning to open farmland. This proximity to agricultural activity is a key factor in air quality, as seasonal burning of crop residue and fertilizer application can release particulate matter and ammonia. The flat topography limits natural dispersion of pollutants, potentially leading to localised build-up, especially during stable atmospheric conditions. Understanding this interplay between agriculture, geography, and urban form is crucial for assessing and mitigating air quality challenges in Beyləqan.

Beyləqan experiences a semi-arid climate, with distinct seasonal variations impacting air quality. Spring (March-May) often sees increased particulate matter from agricultural preparations – ploughing and initial fertilizer application. Winds can be erratic, sometimes exacerbating dust storms. Summers (June-August) are hot and dry, with generally better air quality due to increased atmospheric mixing, though ozone formation can be a concern during prolonged heatwaves. However, irrigation practices can contribute to localised humidity and potential mould spore release. Autumn (September-November) is a critical period. The post-harvest burning of crop residue, particularly cotton stalks, dramatically increases particulate matter concentrations, often creating hazy conditions. Temperature inversions become more frequent, trapping pollutants near the ground. Winters (December-February) are relatively mild but can experience periods of stagnant air, leading to accumulation of pollutants from domestic heating sources – wood and coal burning are common. Fog is also prevalent, trapping pollutants and reducing visibility. Sensitive individuals, including those with respiratory conditions, should limit outdoor activity during autumn burning season and periods of winter fog. Monitoring wind patterns and avoiding outdoor exertion during calm, cold days is advisable.
