Jūnqān, nestled within the Chahār Maḩāl va Bakhtīārī Province of Iran, occupies a geographically significant position in the Zagros Mountains. Located at coordinates 32.1522° N, 50.6911° E, the city sits at an elevation of approximately 2,030 meters (6,660 feet), contributing to a cooler, mountainous climate. The surrounding landscape is dominated by rugged terrain, steep slopes, and deep valleys characteristic of the Zagros range. This mountainous setting significantly influences air quality, limiting atmospheric dispersion of pollutants. Jūnqān is not proximate to any major bodies of water; its water sources are primarily derived from mountain springs and rainfall. The region is largely rural, with agriculture – particularly animal husbandry and some dryland farming – being the dominant economic activity. While Jūnqān itself is a relatively small city with a population of around 14,433, its location along transportation routes connecting regional centres means it experiences some through-traffic. The urban-rural gradient is steep, with quickly transitioning landscapes from built-up areas to open pastureland and forested slopes. Dust storms originating from the western and southern deserts can impact air quality, carried by prevailing winds. The valley location can also trap pollutants during periods of calm weather, exacerbating local air quality issues.

Jūnqān experiences a distinct seasonal air quality pattern dictated by its mountainous climate. Spring (March-May) sees improving conditions as snowmelt cleanses the atmosphere, though agricultural burning can temporarily elevate particulate matter. Summers (June-August) are generally drier with clearer skies, offering the best air quality, but occasional dust storms from the southwest can bring significant short-term pollution spikes. Autumn (September-November) marks a transition period; decreasing temperatures lead to increased heating demands, potentially raising levels of combustion-related pollutants. This is also a period of increased agricultural activity, contributing to localised smoke. Winters (December-February) are the most challenging for air quality. Cold temperatures promote temperature inversions, trapping pollutants close to the ground. Increased reliance on solid fuels for heating – wood and coal – significantly elevates particulate matter and sulfur dioxide concentrations. Sensitive groups, including children, the elderly, and those with respiratory conditions, should limit outdoor exertion during winter months and periods of calm weather. Months to avoid prolonged outdoor activity are December, January, and February. Monitoring wind patterns is crucial; northerly winds generally bring cleaner air, while southerly winds can carry pollutants from more industrialised areas.
