Abstract
Several wet ashing techniques for trace mercury analysis by cold vapour atomic absorption have been evaluated with radiotracer mercury, and in particular fish labelled in vivo with 203Hg-tagged methylmercury chloride. Partial digestion methods suffer from strong matrix effects; these include incomplete extraction from the sample, hold-back of mercury in the extraction solution during the reduction/aeration step, and alteration of the aeration release pattern so as to cause low results if measurement is based on peak height. A complete digestion method is outlined; this gives good results and is tentatively recommended pending further tests with other types of biological samples.
