Neutron activation analysis and the gas-chromographic techniques are used in the determination of organomercury compounds and of total mercury in environmental matrices. In this work the benzene-cysteine separation procedure of Westoeoe was coupled to neutron activation analysis. In this way both the total mercury content and the organomercury fraction can be evaluated in one sample and during one radiochemical separation process. The activity of /sup 197/Hg from the inorganic mercury content of the samples has been evaluated with a well-known combustion separation technique, carried out on the residual sample after benzene extraction. The activity of /sup 197/Hg from organomercury compounds of the samples has been evaluated after extraction and purification with cysteine acetate from benzene fraction. The total mercury content was checked on an untreated portion of the same sample.
