Salton Sea Dust Stunts Children's Lung Growth
3 Apr
Summary
- Toxic dust from the drying Salton Sea impedes children's lung development.
- Children living near the exposed lakebed show greater lung function impairment.
- Future industrial activity and water diversion may worsen air pollution.
Southern California's Salton Sea, once a thriving resort, is now a drying, toxic landscape. As the lake recedes, wind blows harmful dust from its exposed bed, significantly impacting children's respiratory health.
New research from USC and UC Irvine indicates this dust impedes lung growth, particularly in children nearest the Salton Sea. These effects are more pronounced than those observed in urban areas near busy roads, highlighting a critical environmental health crisis.
The lake's diminishing water sources, due to agreements on Colorado River water use and potential lithium extraction projects, suggest air pollution will worsen. This exacerbates existing health concerns in the predominantly low-income communities surrounding the sea.
The AIRE cohort study followed over 700 children, finding that early-life lung damage increases risks for chronic adult health problems. Protecting local air quality is deemed crucial for the Imperial Valley's children's health.
