Dursunbey, nestled within the Balıkesir province of Turkey, occupies a geographically significant position in the northwest Anatolian region. Located at approximately 39.5878° N, 28.6275° E, the city sits at an elevation of around 285 meters (935 feet) above sea level, contributing to a relatively mild climate. The surrounding landscape is characterized by a blend of rolling hills and fertile plains, indicative of the broader Aegean region’s topography. Dursunbey’s terrain is gently undulating, facilitating agricultural activities which are a cornerstone of the local economy. The city’s proximity to the Manyas Plain, a vital wetland ecosystem, influences local weather patterns and biodiversity. While not directly adjacent to a major body of water, the region benefits from the moderating influence of the Aegean Sea, albeit at a distance. The urban fabric of Dursunbey is primarily characterized by a gradual urban-rural gradient; the city itself is a modest-sized settlement, transitioning quickly into agricultural lands and smaller villages. Significant industrial activity is limited, with the economy largely reliant on agriculture (olives, grains, and livestock) and related processing. This reduces baseline industrial pollution. However, agricultural practices, including fertilizer use and seasonal burning of crop residues, can contribute to localized air quality fluctuations. The prevailing winds, generally from the west and northwest, play a crucial role in dispersing pollutants, though topographic features can sometimes create localized pockets of stagnant air, particularly during periods of calm weather. The surrounding agricultural belt, while generally beneficial, can introduce particulate matter and volatile organic compounds into the atmosphere.

Dursunbey’s air quality experiences a distinct seasonal cycle dictated by meteorological conditions and agricultural practices. Spring (March-May) typically sees improved air quality as temperatures rise and winds increase, dispersing any lingering winter pollutants. However, this period also coincides with the start of agricultural activities, potentially introducing dust and pollen into the air, impacting those with allergies. Summer (June-August) is generally the cleanest period, with consistent winds and high temperatures promoting good ventilation. The dry conditions, however, can increase the risk of wildfires in the surrounding agricultural areas, which would significantly degrade air quality. Autumn (September-November) marks a shift, with decreasing temperatures and calmer winds. This often leads to temperature inversions, trapping pollutants near the ground, particularly in the mornings. Agricultural burning of crop residues is also more prevalent during this season, contributing to increased particulate matter. Winter (December-February) is often the most challenging period. Cold temperatures and frequent fog events reduce atmospheric mixing, leading to stagnant air and the potential for pollutant accumulation. Sensitive groups, such as children, the elderly, and individuals with respiratory conditions, should limit prolonged outdoor exposure during these months, especially during periods of fog or calm weather. Maintaining indoor air quality through proper ventilation and air purification can be beneficial. The agricultural cycle, with its associated practices, is a key driver of seasonal air quality variations, requiring careful management to minimize impacts on public health.
