Salton Sea is emitting foul-smelling hydrogen sulfide gas, triggering health concerns [View all]
On scorching days when winds blow across the California desert, the Salton Sea regularly gives off a stench of decay resembling rotten eggs.
New research has found that the shrinking lake is emitting the foul-smelling gas hydrogen sulfide more frequently and at higher levels than previously measured.
The findings document how the odors from the Salton Sea add to the air quality problems and health concerns in communities near the lake, where windblown dust drifts from exposed stretches of lakebed and where people suffer from high rates of asthma and other respiratory illnesses.
“The communities around the Salton Sea are on the front lines of a worsening environmental health crisis,” said Mara Freilich, a co-author of the study and assistant professor in Brown University’s Department of Earth, Environmental and Planetary Sciences.
