Core samples were collected from the Sabine River and Toledo Bend Reservoir beds, digested, and analyzed using atomic absorption spectroscopy for several heavy metals. The magnitude of heavy metal concentrations in the bed sediments and the pattern of deposition can help determine which heavy metals are present, the source of heavy metals found in the fish (bed sediment or water), and the source of the heavy metal pollution, if any: industrial, geologic, or atmospheric.
