Toxic threat: Utah's Great Salt Lake endangers millions
The Great Salt Lake in the United States is threatening 1.2 million residents. Record low water levels and toxic sediments present serious issues.
Located in the state of Utah, the Great Salt Lake, one of the saltiest lakes in the world, is gradually shrinking. Its salinity is three to five times higher than that of the oceans, making it inhospitable to fish. The water level is falling, and the lakebed contains toxic substances like arsenic, a chemical compound found as arsenic trioxide. This poses a direct threat to the 1.2 million people living nearby.
The lake as a ticking time bomb
Climate change and excessive water resource exploitation mainly contribute to the lake's declining water levels. The situation mirrors that of the Aral Sea, which almost wholly vanished. As the lake dries, it exposes sediments laced with harmful substances.
Research led by Professor Kevin Perry from the University of Utah has identified arsenic and other heavy metals in the lake's sediments. These toxic particles are released into the air, polluting the area around the lake and significantly degrading air quality. This adversely affects the health of millions.
The region surrounding the Great Salt Lake is also crucial for migratory birds. The decreasing number of birds visiting this area highlights another negative consequence of the lake's decline. Industrial activity profits are also dwindling. The issue demands urgent intervention to avert further damage.
The situation raises concerns
Residents of Utah openly express their worries. Arsenic absorption can be very dangerous, potentially leading to poisoning and even contributing to cancer development. Long-term exposure to arsenic increases the risk of developing cancers of the skin, bladder, lung, kidney, liver, and prostate.
