Dakar shrouded in dust, Sahara blanket lingers, health risks escalate

For the fourth consecutive day, Dakar, the vibrant capital of Senegal, found itself under an unusual cloak of dust, transforming the sunny city into a scene reminiscent of the Covid-19 pandemic.

The Atlantic coast, typically bathed in sunlight, now wears a pallid veil, with residents compelled to don facemasks due to the enveloping layer of dust, predominantly blown in from the Sahara.

Senegalese authorities issued warnings of “very poor air quality” and highlighted health risks, particularly for vulnerable groups.

Aminata Mbow Diokhane, from the air quality management centre (CGQA) associated with the environment ministry, pointed out that the pollution peak is attributed to particles of desert origin from the Sahara.

This phenomenon isn’t confined to Dakar alone, as the entire West African country grapples with the pervasive dust.

In a statement on Thursday, the CGQA declared that air quality in Dakar is “very poor overall.” Disturbingly, concentrations of particulate matter (PM10) have surged to levels exceeding 900 micrograms per cubic meter, nearly 20 times the maximum recommended by the World Health Organization for 24-hour exposure.

Senegal’s National Civil Aviation and Meteorology Agency (ANACIM) echoed concerns, indicating a “high” health risk for individuals with respiratory illnesses, young children, and the elderly. The situation, described as a pollution peak, is expected to persist until at least Sunday, according to weather forecasters.

Aminata Mbow Diokhane explained that these weather events are typical in Senegal between mid-November and the end of March, typically lasting for at least three days. Ngor Ndiaye, a forecaster at ANACIM, added that if this phenomenon extends beyond a week, there would be cause for heightened concern among the population.

As Dakar waits for clearer skies, the health risks associated with the Sahara’s persistent dust remain a pressing issue for the city’s residents.
