Baseline Concentrations of Total Mercury and Methylmercury in Salmon Returning Via the Bering Sea (1999–2000)

The baseline of mercury and its speciation in salmon muscle and liver was determined by analysis of samples collected from sites on four major rivers in western Alaska during the summers of 1999 and 2000. In 1999, total Hg in individual salmon muscles were in the 25-137 ng/g range, and were in the 2...

Description
Summary:The baseline of mercury and its speciation in salmon muscle and liver was determined by analysis of samples collected from sites on four major rivers in western Alaska during the summers of 1999 and 2000. In 1999, total Hg in individual salmon muscles were in the 25-137 ng/g range, and were in the 20-105 ng/g range in 2000. Mean total Hg levels in liver were in the 54-112 ng/g range. Total Hg and methylmercury concentrations in salmon muscles correlated, and mean methylmercury levels were lower than total Hg means. Total Hg concentrations increased with fish lengths.
