Bni Darkoul, a small municipality within the Tanger-Tétouan-Al Hoceïma region of Morocco, is geographically positioned at 35.0563°N, -5.0688°W. The town sits nestled in the foothills of the Rif Mountains, a range known for its rugged terrain and forested slopes. This location, approximately 15km inland from the Strait of Gibraltar and the city of Tangier, significantly influences its air quality. The surrounding landscape is a mix of agricultural land – primarily olive groves and small-scale farming – and increasingly, areas undergoing residential and light industrial development. Bni Darkoul’s elevation, around 200-300 meters above sea level, contributes to localized temperature inversions, trapping pollutants during calm weather conditions. The proximity to Tangier, a major port and industrial hub, means the town is susceptible to the transport of pollutants via prevailing winds, particularly from the west. The urban-rural gradient is relatively sharp; transitioning quickly from the denser, more developed areas closer to Tangier to the more rural, agricultural lands further inland. This gradient impacts pollutant dispersion, with Bni Darkoul acting as a buffer zone, but also experiencing the fallout from regional emissions. The Mediterranean climate, characterised by hot, dry summers and mild, wet winters, further shapes the atmospheric conditions and pollutant behaviour.

Air quality in Bni Darkoul follows a distinct seasonal pattern dictated by meteorological conditions and human activity. Summer (June-August) often sees a rise in ground-level ozone due to intense sunlight and high temperatures reacting with vehicle emissions and industrial byproducts from nearby Tangier. Dry conditions and stable air masses exacerbate this, leading to stagnant air. Autumn (September-November) brings a slight improvement as temperatures cool and rainfall increases, washing away some particulate matter. However, agricultural burning of crop residue during this period can cause localised spikes in PM2.5. Winter (December-February) is generally the period of poorest air quality. Increased use of solid fuels for heating, combined with temperature inversions common in the Rif Mountains, traps pollutants close to the ground. Fog, frequent during these months, further reduces dispersion. Spring (March-May) offers a gradual improvement as temperatures rise and rainfall increases, diluting pollutant concentrations. Sensitive groups – children, the elderly, and those with respiratory conditions – should be particularly cautious during winter and summer months. Avoiding strenuous outdoor activity during peak pollution periods and monitoring local conditions is advisable. The prevailing winds from the west can bring pollutants from Tangier, so awareness of conditions in the larger city is also important.
