Sublethal concentrations of mercury in river otters: monitoring environmental contamination

Autor: Parshall B. Bush, J. H. Jenkins, N. D. Seabolt, R. S. Halbrook

Publikováno v: Archives of environmental contamination and toxicology. 27(3)

Hair, muscle, and liver mercury concentrations were determined in river otter (Lutra canadensis) carcasses collected from the lower coastal plain and piedmont of Georgia. Mean muscle and hair mercury concentrations were greater (P0.001) in otters fro

In recent years technical developments have enhanced our ability to detect and quantify biological changes that occur at the molecular, cellular, and physiological levels following exposure to chemicals in the environment. Although strategies for res

Characterizing biological variability in livestock blood cholinesterase activity for biomonitoring organophosphate nerve agent exposure

Autor: R S, Halbrook, L R, Shugart, A P, Watson, N B, Munro, R D, Linnabary

Publikováno v: Journal of the American Veterinary Medical Association. 201(5)

A biomonitoring protocol, using blood cholinesterase (ChE) activity in livestock as a monitor of potential organophosphate nerve agent exposure during the planned destruction of US unitary chemical warfare agent stockpiles, is described. The experime

Cesium-137 levels detected in Georgia otters

Autor: James H. Jenkins, R. S. Halbrook

Publikováno v: Bulletin of Environmental Contamination and Toxicology. 41:765-769

Beginning in the 1940's and continuing through the 50's and early 60's, nuclear devices were tested by aerial detonation in the United States and other countries around the world. Cesium-137 (/sup 137/Cs) is one of the most important radionuclide by-
