Sandstorm in Iraq

At least 3,700 people were hospitalized with respiratory issues in Iraq this week after a large sandstorm swept across the region from Saudi Arabia, filling the skies with an orange haze and reducing visibility to only half a mile. Much of Baghdad, including airports and highways, has been shut down since Sunday as the tiny particles forced people indoors.

Sand or dust storms occur in dry or drought-ridden regions like deserts or plains and valleys with substantial clay and silt deposits (see map). High wind speeds lift the particles and move them potentially hundreds of miles, reducing the sun’s light and heat. When inhaled, the fine particles can irritate the lungs, potentially leading to infections. Mechanical equipment is also vulnerable to corrosion and clogs from the dust. 

Sandstorms have been common in Iraq for millennia, occurring weekly on average during peak seasons, though this week’s event is relatively severe. Read how a dust storm played a key role during the US invasion of the country here.
