Drying Lakes Raise Dust Health Risks

Shrinking saline lakes in California and Utah are exposing more lakebed, raising concern that windblown dust may worsen respiratory risks for nearby communities, especially children and people with asthma.

Research around the Salton Sea links greater dust and air-pollution exposure with poorer respiratory symptoms and reduced lung growth, while health risks from heavy metals in Great Salt Lake dust remain less well measured. Authorities are pursuing shoreline restoration, water-conservation measures, monitoring networks, and dust forecasts, but the scale of exposure and effectiveness of these responses remain uncertain.
