Banī Murr, nestled within the Asyūţ Governorate of Egypt, occupies a significant position along the Nile River, at approximately 27.2240°N latitude and 31.1955°E longitude. The city’s terrain is largely flat, characteristic of the Nile Valley, with an elevation hovering around 42 meters above sea level. This low-lying geography, coupled with its proximity to the Nile, influences local meteorological conditions and, consequently, air quality. The surrounding landscape is dominated by agricultural lands, intensely cultivated due to the fertile Nile silt, and interspersed with small desert expanses further from the riverbanks. Banī Murr isn’t a major industrial hub, but regional agricultural processing and smaller-scale manufacturing contribute to localised emissions. The urban-rural gradient is relatively sharp; the city itself is compact, quickly transitioning to farmland. The Nile acts as a partial conduit for air movement, but temperature inversions, common in the valley during cooler months, can trap pollutants. Dust from surrounding agricultural activities and the western desert also plays a role, particularly during the *khamsin* winds. The city’s location within the Nile Valley creates a microclimate susceptible to humidity and limited air circulation, impacting pollutant dispersion.

Banī Murr experiences a hot desert climate, with distinct seasonal variations impacting air quality. Summer (June-August) brings intense heat and dry conditions. While winds can offer some dispersion, high temperatures promote the formation of ground-level ozone from vehicle and industrial emissions, potentially worsening respiratory conditions. Autumn (September-November) offers a reprieve with cooler temperatures and reduced ozone formation, making it a more favourable time for outdoor activities. However, agricultural burning of crop residue after harvest becomes prevalent during this period, significantly increasing particulate matter (PM2.5 and PM10) levels. Winter (December-February) is characterised by cooler temperatures and increased frequency of temperature inversions, trapping pollutants near the ground and leading to poorer air quality. Fog can also exacerbate these conditions. Spring (March-May) sees a gradual warming trend and the potential for *khamsin* winds, bringing dust storms from the western desert, dramatically increasing particulate matter. Sensitive groups – children, the elderly, and those with respiratory illnesses – should limit outdoor exposure during peak agricultural burning in autumn and dust storm events in spring. Monitoring local conditions and staying indoors on high-pollution days is crucial.
