Cumayeri, nestled within the Düzce Province of Turkey, occupies a geographically significant position in the Black Sea region. Located at coordinates 40.8736, 30.9508, the town is characterized by a landscape of rolling hills and valleys, typical of the North Anatolian mountain range. Its elevation, approximately 220 meters above sea level, influences local weather patterns and air circulation. Cumayeri is situated inland, approximately 25 kilometers from the Black Sea coast, meaning direct maritime influences are moderated by the intervening terrain. The surrounding area is predominantly agricultural, with significant hazelnut orchards – a key economic driver for the region – and mixed farming. While not a heavily industrialized zone, the presence of smaller-scale manufacturing and processing facilities related to agriculture contributes to localized emissions. The urban-rural gradient is quite sharp; Cumayeri itself is a relatively small town, quickly transitioning to rural farmland and forested areas. This proximity to agricultural land means potential for particulate matter from field preparation and seasonal burning. The valley location can also trap pollutants during periods of stagnant air, exacerbating air quality concerns. The terrain funnels winds, creating localized variations in pollutant dispersion.

Cumayeri experiences a temperate climate with distinct seasonal variations that profoundly impact air quality. Winters (December-February) are typically cold and damp, often with fog, which traps pollutants near the ground, leading to increased concentrations of particulate matter from residential heating using wood and coal. Temperature inversions are common during these months, further worsening conditions. Spring (March-May) brings increased rainfall, which helps to cleanse the atmosphere, resulting in generally improved air quality. However, agricultural activities, such as field preparation and burning of agricultural waste, can temporarily elevate particulate matter levels. Summers (June-August) are warm and relatively dry, with prevailing winds aiding in pollutant dispersion, offering the best air quality of the year. Autumn (September-November) sees a return to increased heating demands, coupled with the potential for stagnant air masses, leading to a gradual decline in air quality. Sensitive individuals, including those with respiratory conditions, should be particularly cautious during the winter months and periods of agricultural burning. Avoiding strenuous outdoor activity on still, cold days is advisable. Monitoring local conditions and limiting exposure during peak pollution times is crucial for maintaining respiratory health.
