Abstract Lung disease is rampant around the Salton Sea, California’s largest inland lake and a major source of airborne particulates. To examine root causes of pulmonary disease, we investigated the exposure impacts of spatiotemporal variation in aerosols collected near the Salton Sea on lung and fecal microbiomes. We collected dust during the summer and fall at three different sites around the Salton Sea from 2020 to 2022.
Abstract Introduction: The aeolian dust microbiome is composed of uniquely adapted microorganisms that can withstand the harsh conditions of the atmosphere. Specific microbial taxa and survival strategies have been observed in dust microbiomes from around the world, yet the environmental processes that select for microbial composition and function are poorly understood.

The Salton Sea Basin in California suffers from poor air quality, and an expanding dry lakebed (playa) presents a new potential dust source. In 2017–18, depositing dust was collected approximately monthly at five sites in the Salton Sea Basin and analyzed for total elemental and soluble anion content. These data were analyzed with Positive Matrix Factorization (PMF).
