Analysis of soil samples from the San Joaquin Valley of California (original) (raw)

This research focuses on a detailed geochemical analysis of soil samples collected from the San Joaquin Valley, California. Initially part of a broader survey by the U.S. Geological Survey, the study shifted to prioritize surface soil samples following concerns about high selenium levels affecting wildlife. Advanced analytical methods were employed to assess the chemical composition of the soils, aiming to understand the distribution of trace and major elements and their potential impacts on the environment.
