Professor and marine biologist Alan Deidun has shared a striking satellite image capturing a massive Saharan dust cloud sweeping northward across the Mediterranean. The dense haze has cast a dusty veil over Malta, significantly reducing visibility and affecting air quality, and is expected to persist till the end of the week.

Unfortunately this atmospheric phenomenon isn’t just a nuisance leading to dirty cars and windows - it comes with real health risks. The dust carries fine particulate matter known as PM2.5, microscopic particles small enough to enter the bloodstream when inhaled. These pollutants are among the most harmful to human health, potentially triggering respiratory issues, irritation, and long-term complications.

According to air quality tracking site aqi.in, Malta’s PM2.5 concentration is currently 2.2 times higher than the World Health Organization’s recommended annual guideline. The country’s Air Quality Index (AQI) is averaging around 100, classified as ‘Poor,’ meaning that while the general public may experience minor effects, sensitive groups are at higher risk and should limit outdoor exposure if experiencing discomfort.

But there’s a silver lining - Saharan dust isn’t all bad news. This natural phenomenon also acts as a fertiliser, enriching Malta’s soil and marine ecosystems with vital nutrients. So while the air may be thick with dust, nature is quietly making the most of it. Stay indoors if needed, and let’s hope for clearer skies ahead!

Are you feeling the effects of the dusty air?
