Edremit, nestled within the Van Province of eastern Turkey, occupies a unique geographic position at coordinates 38.4242° N, 43.2561° E. The city is situated on a plateau, part of the broader Eastern Anatolian Region, at an elevation of approximately 1,650 meters (5,413 feet) above sea level. This high altitude significantly influences its climate and, consequently, its air quality. Edremit is positioned relatively close to Lake Van, Turkey’s largest lake, which moderates temperatures to some extent but also contributes to potential humidity and fog formation. The surrounding landscape is characterised by rugged mountains and expansive steppes, typical of the Anatolian interior. While Edremit isn’t a major industrial hub, the region supports substantial agricultural activity, particularly livestock farming and dryland agriculture. This agricultural practice can contribute to particulate matter pollution through dust from fields and animal husbandry. The urban-rural gradient is relatively sharp, with agricultural lands immediately bordering the city limits. The prevailing winds, often originating from the west and northwest, can transport pollutants from surrounding areas, impacting local air quality. The terrain’s topography, with its valleys and plateaus, can also trap pollutants, exacerbating air quality issues during periods of calm weather. Understanding these geographical factors is crucial for assessing and mitigating air pollution in Edremit.

Edremit experiences a continental climate with distinct seasonal variations that profoundly impact air quality. Winters (December-February) are long, cold, and snowy, often accompanied by temperature inversions that trap pollutants near the ground, leading to increased concentrations of particulate matter from heating sources – primarily coal and wood burning for residential warmth. Spring (March-May) brings a gradual thaw and increased agricultural activity, potentially raising dust levels. However, increased precipitation helps to cleanse the air. Summers (June-August) are warm and dry, with generally good air quality due to wind dispersal, though occasional dust storms can occur. Autumn (September-November) sees a return to calmer conditions and increased heating demand, leading to a gradual deterioration in air quality. October and November are often the most polluted months. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during winter and late autumn. Fog, common in the colder months, can exacerbate respiratory issues. Monitoring wind patterns is crucial; westerly winds generally improve air quality, while stagnant conditions worsen it. Avoiding outdoor exercise during peak heating hours in winter is advisable. The dry conditions in summer can also trigger wildfires in surrounding areas, contributing to temporary spikes in particulate matter.
