Būr Fu’ād, nestled within the Būr Sa‘īd governorate of Egypt, occupies a strategically important position on the eastern edge of the Nile Delta, approximately 20 kilometers east of Alexandria. Its coordinates (31.2314, 32.3253) place it in a low-lying coastal plain, characterized by fertile agricultural land and a gently undulating terrain. The city’s proximity to the Mediterranean Sea significantly influences its climate and, consequently, its air quality. The surrounding landscape is dominated by expansive fields of cotton, corn, and other crops, forming a distinct urban-rural gradient as Būr Fu’ād transitions from agricultural zones to more densely populated areas. To the west, the Nile River acts as a natural boundary, while eastward, the terrain gradually rises, though remaining relatively flat. The city’s elevation is minimal, rarely exceeding 10 meters above sea level, which can exacerbate the trapping of pollutants, particularly during periods of calm weather. Industrial activity, though not as extensive as in Alexandria, is present, with smaller-scale manufacturing and processing facilities contributing to localized emissions. The prevailing winds, generally from the northwest during much of the year, can transport pollutants from Alexandria and other coastal areas, impacting Būr Fu’ād’s air quality. The flat topography and coastal location combine to create conditions where sea breezes and land breezes interact, influencing the dispersion of airborne contaminants and creating microclimates within the city.

Būr Fu’ād’s air quality experiences a distinct seasonal cycle dictated by its Mediterranean climate. The summer months (June-August) are typically characterized by high temperatures and reduced wind speeds, frequently leading to temperature inversions where a layer of warm air traps cooler air and pollutants near the ground. This stagnation results in a build-up of emissions from local sources and those transported from Alexandria. Dust storms, originating from the Sahara Desert, can also significantly degrade air quality during these months, carrying fine particulate matter. Spring (March-May) and Autumn (September-November) generally offer improved conditions, with more frequent winds dispersing pollutants. However, fog, common during these transitional periods, can temporarily reduce visibility and trap pollutants. Winter (December-February) brings cooler temperatures and increased rainfall, which helps to cleanse the atmosphere, leading to the best air quality of the year. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the summer months, limiting outdoor activities during peak heat and dust storm events. Maintaining indoor air quality through proper ventilation and air filtration is particularly important. The agricultural practices surrounding Būr Fu’ād, including the use of fertilizers and pesticides, can also contribute to seasonal fluctuations in air quality, particularly during planting and harvesting periods. Awareness of prevailing wind directions and local weather forecasts can aid in minimizing exposure to potentially harmful air pollutants.
