The Determination of Trace Metals in Marine Organisms by Atomic Absorption Spectrometry

Abstract
The application of atomic absorption spectrometry to the analysis of trace metals in marine organisms is described. The samples are digested with nitric acid in teflon decomposition vessels. Mercury is determined by the cold-vapor method while the other elements are determined by flame atomization or flameless graphite-furnace atomization. Several marine species of economic importance. are analyzed for seven trace elements.
