Determinations of sulfide levels were made for estuarine and freshwaters. Comparison of results were made using three different analytical techniques. Differential pulse cathodic stripping voltammetry (DPCSV), the silver/sulfide electrode, and a spectrophotomeric method using Lauth's violet dye. The detection limit of the DPCSV technique is 17.1 nM S/sup =/ at 3 sigma or one order of magnitude more sensitive than other accepted techniques. Sampling procedures, sulfide stabilization, and storage are discussed. 10 references, 2 tables.
