    Summary

    Industrial emissions are the primary source of atmospheric sulfur compounds in Salt Lake City annually. However, sulfur from anaerobic mud bacteria becomes significant seasonally, potentially matching industrial contributions.

    Area of Science:

    • Environmental Science
    • Atmospheric Chemistry
    • Geochemistry

    Background:

    • Salt Lake City faces atmospheric sulfur compound pollution.
    • Understanding sulfur sources is crucial for environmental management.

    Purpose of the Study:

    • To identify and quantify the sources of atmospheric sulfur compounds in Salt Lake City.
    • To compare the significance of industrial and natural sulfur sources.

    Main Methods:

    • Isotopic analysis of atmospheric sulfur compounds.
    • Assessment of industrial emissions data.
    • Evaluation of bacteriogenic sulfur release from muds.

    Main Results:

    • Industrial activities are the dominant annual source of atmospheric sulfur.
    • Bacteriogenic sulfur from anaerobic muds is a significant secondary source.
    • Seasonally, bacteriogenic sulfur can rival industrial sulfur in atmospheric contribution.

    Conclusions:

    • Both industrial and natural (bacteriogenic) sources contribute to Salt Lake City's atmospheric sulfur.
    • Seasonal variations in bacteriogenic sulfur release impact its overall importance.
