The Saharan dust can negatively impact air quality, increasing particulate matter in the air. This can lead to respiratory issues, especially for vulnerable groups such as children, older adults, and individuals with heart or lung conditions. Symptoms may include asthma flare-ups, allergy-like reactions, and skin or eye irritation. The dust can also contribute to harmful algal blooms in oceans, coral bleaching, and vegetation damage. While the dust has ecological benefits, such as fertilizing soils and supporting marine life, its adverse effects on health and the environment remain significant.
