İspir, nestled in the eastern Anatolian region of Turkey within Erzurum Province, presents a unique geographic setting profoundly influencing its air quality. Situated at coordinates 40.4836, 40.9953, the city occupies a high-elevation basin, averaging around 1,500 meters (4,921 feet) above sea level. This mountainous terrain, part of the Pontic Mountains, creates a natural bowl effect, often trapping air masses and exacerbating pollution episodes. The surrounding landscape is dominated by steep slopes, forested areas, and agricultural lands, primarily dedicated to dry farming and livestock grazing. The Karasu River flows nearby, but its influence on local air circulation is limited by the valley’s topography. İspir isn’t located near major industrial belts; however, smaller-scale local industries, including food processing and textile production, contribute to emissions. The urban-rural gradient is relatively sharp, with the city centre transitioning quickly to agricultural and natural landscapes. This proximity to agricultural activities introduces seasonal particulate matter from harvesting and field preparation. The basin’s limited ventilation, combined with heating demands during long, cold winters, creates conditions conducive to pollutant accumulation, making understanding local air patterns crucial for public health.

İspir experiences a harsh continental climate, dictating a strong seasonal pattern in air quality. Winters (November to March) are the most challenging, marked by prolonged snow cover and frequent temperature inversions. These inversions trap cold air, along with emissions from coal and wood-burning stoves used for heating, near the ground, leading to elevated particulate matter concentrations. January and February are typically the months with the poorest air quality. Spring (April-May) brings a gradual improvement as temperatures rise and snow melts, but dust from thawing ground and agricultural activities can temporarily increase particulate matter. Summer (June-August) generally offers the cleanest air, with prevailing winds dispersing pollutants and reduced heating needs. However, dry conditions can lead to increased dust suspension. Autumn (September-October) sees a return to deteriorating conditions as heating season approaches and agricultural burning occurs. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during winter months and periods of agricultural burning. Monitoring wind direction and avoiding activity near heavily trafficked areas are also advisable. Fog, common in the valley during colder months, can further concentrate pollutants.
