African Dust Goes Global
New research looking at air quality in Houston showed that dust clouds from Africa’s Sahara Desert impact the air quality in Texas and other regions of the world. They found that a major dust intrusion in the Sahara doubled the concentration of inhalable particles in Houston, by identifying native Texan dust particles from dust with an African “fingerprint.” The African dust may be bad for asthma and allergies in Texas, but in the Caribbean Basin—where it also travels to—it can affect hurricane activity. They say this effect is a very complex relationship and requires more research.
