Great Salt Lake, Greater Toxicity
As the Great Salt Lake (Utah, USA) continues to shrink, exposing more of its lakebed, concerns are growing about the potential health impacts of dust from this increasingly barren landscape.
Researchers from the University of Utah have recently conducted a study focusing on the chemical composition of dust particles originating from the exposed lakebed. To investigate the composition of these dust particles, the research team used inductively coupled plasma mass spectrometry (ICP-MS).
The results indicate that the dust from the Great Salt Lake contains elevated concentrations of several metals, including arsenic, lithium, copper, manganese, iron, and lead. Notably, the levels of arsenic and lithium exceeded the US Environmental Protection Agency’s residential regional screening levels, indicating a potential health risk for populations living downwind of the lake.

This week we reflect back on Pieter Dorrestein's journey to make mass spec more impactful through innovation and open science.
“One day, MS will be incorporated into smartphones, allowing consumers to conduct analysis in real-time. When will that happen? It will depend on whether the community makes an effort to organize itself; if it does not, I fear that progress will continue at a snail’s pace,” he said in the interview.
What do you think are the biggest challenges or opportunities in making this vision a reality? Has the community managed to make any progress?
