Radionuclide and Heavy Metal Concentrations in Fish from the Confluences of Major Canyons That Cross Los Alamos National Laboratory Lands with the Rio Grande
Bottom-feeding fish--catfish, suckers, and carp--that were collected from the confluences of some of the major canyons that cross LANL lands with the Rio Grande (RG) exhibited similar radionuclide (with the exception of {sup 90}Sr), and nonradionuclide concentrations to fish collected upstream of any potential LANL contamination sources. Strontium-90 concentrations in fish from LANL canyons/RG may be associated with LANL operations; however, the concentrations of {sup 90}Sr in fish decrease to background concentrations further downstream of LANL at CR. And, based on the most conservative assumptions (a 95% source term and maximum consumption rate), LANL operations do not result in significant doses to the general public from consuming fish along the length of the RG as it passes through the eastern edge of LANL lands to CR. Moreover, since over 85% of the doses were a result of {sup 90}Sr detected in the muscle plus bone portions of the fish and most of the {sup 90}Sr is associated with the bone, the doses to people that consume only the edible portions of the fish (muscle only), would be significantly lower.
