Scientists find sediments from the lake's exposed playa have elevated 'oxidative potential,' indicating greater risk to human health compared with other dust sources affecting Salt Lake City .

Chemical analysis also indicated the presence of numerous metals, and levels of arsenic and lithium that exceed the U.S. Environmental Protection Agency's soil residential regional screening levels.

The team aerosolized the sediment samples to isolate the particles that are small enough to inhale and lodge in lung tissue.

These particles were captured on filters and analyzed using a method called inductively coupled mass plasma mass spectrometry to determine their elemental makeup and other tests.

Meanwhile, high OP was detected in dust associated with certain metals, including copper, manganese, iron and aluminum.
