marine mammals stranded along the Oregon and Washington coasts (2002–2009) were 
tested for levels of total mercury (THg) by Cold Vapor Atomic Fluorescence 
Spectrometry. The THg present is in the form of the highly toxic methylmercury. 
After normalizing tissue to 75% water weight, Steller sea lions and northern 
elephant seals exhibited the highest mean concentrations of THg followed by 
harbor seals, harbor porpoises, and California sea lions, 0.34 ± 0.278, 0.34 ± 
0.485, 0.21 ± 0.216, 0.17 ± 0.169, and 0.15 ± 0.126 mg/kg normalized wet weight 
(ww), respectively. The mean normalized values demonstrate limited muscle 
methylmercury accumulation in these species in the Pacific Northwest. However, 
actual ww concentrations in some of the stranded carcasses may pose a risk to 
scavengers. Normalizing muscle mercury concentrations eliminated the 
variability from desiccation, and allowed for a clearer indication of the 
amount of mercury the animal accumulated before stranding.
