Buharkent, nestled within Aydın Province in southwestern Turkey, occupies a geographically significant position at approximately 37.96°N, 28.74°E. The town sits within the fertile Meander River basin, a historically crucial agricultural region. Its terrain is characterized by gently rolling hills transitioning into a broader alluvial plain, a consequence of the Meander’s historical shifts and deposition. Elevation ranges from around 60 meters near the river to approximately 150 meters at the periphery, influencing local wind patterns and potential for temperature inversions. Buharkent’s location is crucial; it lies on the edge of a significant agricultural belt, dominated by olive groves, citrus orchards, and vegetable farming, which contributes to both rural character and potential air quality concerns related to agricultural practices. The urban–rural gradient is relatively sharp, with the town bordered by extensive agricultural land. While not directly adjacent to a major body of water, the proximity to the Meander River and its tributaries moderates local temperatures and influences humidity levels. Further east, the Menderes River basin extends, and to the west, the Aegean Sea exerts a moderating influence on the climate. The absence of heavy industry within Buharkent itself is notable, however, the proximity to industrial zones in Aydın city, approximately 40km away, means that pollutants can be transported via prevailing winds, particularly during periods of atmospheric stability. The surrounding landscape is predominantly agricultural, with scattered villages and rural settlements, contributing to a generally open and airy environment, though localized agricultural emissions remain a factor.

Buharkent’s air quality experiences a distinct seasonal cycle heavily influenced by its Mediterranean climate. Summers (June-August) are typically hot and dry, with stagnant air conditions often leading to the accumulation of pollutants from agricultural activities, such as pesticide spraying and fertilizer application. The intense heat suppresses vertical mixing, exacerbating this issue. While the Aegean Sea breeze provides some relief, its effectiveness is limited during prolonged heatwaves. Spring (March-May) brings a gradual improvement as temperatures cool and rainfall increases, dispersing accumulated pollutants. However, pollen levels rise significantly, impacting individuals with respiratory sensitivities. Autumn (September-November) is generally the most pleasant period for air quality, with moderate temperatures, increased rainfall, and more frequent wind events that effectively flush out pollutants. The agricultural harvest season in autumn can, however, temporarily elevate particulate matter levels due to field clearing and processing. Winters (December-February) are mild and relatively wet, with occasional fog, which can trap pollutants near ground level, particularly in the mornings. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should exercise caution during the summer months and on foggy winter mornings. Agricultural workers should prioritize protective measures during peak spraying periods. Outdoor activities are generally best enjoyed during the autumn months when the combination of moderate temperatures and increased rainfall contributes to improved air quality. The lack of significant industrial activity within Buharkent itself means that the primary air quality concerns are linked to agricultural practices and regional transport of pollutants.
