Note

A field method for the preconcentration of traces of mercury from natural waters onto gold is presented. Mercury (II) ions, methyl mercury compounds, and phenylmercury compounds are reduced in the field to metallic mercury by reaction with sodium borohydride and scrubbed from solution onto a gold sampling tube. Mercury is determined using a helium-dc plasma emission spectrometer system, set on the 2537-A mercury line. The lower detection limit is 0.5 ppt for a 20-mL sample, with a relative standard deviation of less than 2%. Samples down to 1 ppt total mercury have been analyzed.
