Evergreen Needle Magnetization as a Proxy for Particulate Matter Pollution in Urban Environments

GeoHealth, 2020
We test the use of magnetic measurements of evergreen needles as a proxy for particulate matter pollution in Salt Lake City, Utah. Measurements of saturation isothermal remanent magnetization indicate needle magnetization increases with increased air ...
