X-ray fluorescence was used to estimate the concentration of potentially toxic metals in various soil samples. Soil was taken from separate locations in the city of Chicago which are in the vicinity of industrial activities involving metals. A background soil sample was also taken at a location in Saint Charles, Illinois away from suspected industrial use of metals. Fluorescence yield scans were taken for each of the samples at DND-CAT’s station 5BMD, and x-ray absorption near edge structure (XANES) scans were collected on a subset of samples to compare and contrast the types of metal compounds present.
