I‘zāz, nestled within the Ḩalab Governorate of Syria, occupies a strategically significant position in the northern part of the country. Located at coordinates 36.5866° N, 37.0463° E, the city sits approximately 38km northeast of Aleppo, a major urban centre. The terrain surrounding I‘zāz is characterised by rolling hills and plains, part of the broader Euphrates Basin. The elevation is moderate, around 300 meters above sea level, influencing local wind patterns and contributing to temperature variations. While not directly adjacent to a major body of water, the proximity to the Euphrates River, some distance to the south, impacts regional humidity and potential for dust transport. Historically, the area has been a mix of agricultural land – primarily wheat and barley cultivation – and sparsely populated rural areas. The ongoing Syrian Civil War has dramatically altered the urban character, with significant displacement and infrastructure damage. This disruption has led to uncontrolled waste burning and reduced environmental oversight, exacerbating air quality concerns. The urban-rural gradient is blurred by refugee camps and internally displaced person settlements surrounding the city, increasing localised pollution sources. The prevailing winds, often from the northwest, carry pollutants from Aleppo and potentially from further afield, impacting I‘zāz’s air quality.

I‘zāz experiences a Mediterranean climate with hot, dry summers and cool, wet winters. Air quality in I‘zāz is typically poorest during the summer months (June-August). High temperatures promote the formation of ground-level ozone, a key component of smog, and reduced rainfall means pollutants accumulate rather than being washed away. Dust storms, originating from the Syrian Desert and Iraq, are also frequent during this period, significantly increasing particulate matter concentrations. Autumn (September-November) brings a gradual improvement as temperatures cool and occasional rainfall helps to clear the air. However, the practice of burning agricultural residue after harvest can cause localised spikes in pollution. Winter (December-February) sees increased rainfall, generally leading to better air quality, though temperature inversions – where a layer of warm air traps cooler, polluted air near the ground – can occur, especially during calm weather. Spring (March-May) is a transitional period, with fluctuating conditions. The months of July and August are particularly challenging for those with respiratory conditions. Sensitive groups, including children, the elderly, and individuals with asthma, should limit outdoor activity during peak pollution periods and consider using air purifiers indoors. Monitoring wind direction is crucial, as pollutants from regional conflicts can be transported into the area.
