“…The low levels of atmospheric H2S are interesting in light of the fact that sulfide has been observed at nanomolar concentrations in North Atlantic surface waters (Cutter and Oatts, 1987;Luther and Tsamakis, 1989). The latter study suggests that the sulfide may be mostly complexed, which may be a major factor controlling its sea/air exchange rate.…”

“…Recently, Cutter and Oatts (1987) have measured nanomolar concentrations of sulfide in surface seawater. However, the speciation and, hence, volatility of the sulfide has not yet been established.…”

“…This concentration level is very high compared with that, some tens ngS/l, in the oxic surface waters of open oceans. [19][20][21] Dissolved sulfide present in the oxic surface water of open oceans has been thought to be due to the formation of stable metal-sulfide complexes, such as ZnHS + . 21,22 However, the reason why dissolved sulfide exists stable in the oxic epilimnionic water of Lake Nakaumi remains unsolved.…”

Dissolved sulfide in environmental water, which forms HS -rather than H 2 S above pH 7, is produced from microbial sulfate reduction. It is highly toxic to most organisms, and stable only in anoxic aqueous environments, which are linked with water pollution, especially in closed water areas, such as lakes. 1 Therefore, the determination of dissolved sulfide is important for understanding the oxidation-reduction level and water quality in environmental water locations.The Methylene Blue spectrophotometric method is widely used for the determination of dissolved sulfide in water.2-4 Dissolved sulfide in fjord water samples was determined by the Methylene Blue method to clarify its behavior 5 , and the chemical interactions between dissolved sulfide and heavy metals. 6,7 This method was also applied to anoxic seawater samples. 8,9 However, there are serious problems concerning sample collection, the storage and preservation of water samples, and the determination procedure, because dissolved sulfide in water is rapidly oxidized in contact with air and readily escapes as gaseous hydrogen sulfide into the air. Therefore, it is recommended that, immediately after sample collection, dissolved sulfide in a water sample is fixed as zinc sulfide using a zinc acetate solution at sampling sites, and then determined spectrophotometrically in a laboratory. 2,3 However, this method requires one to carry a number of voluminous water samples containing the zinc sulfide precipitate back to the laboratory from the sampling sites. It appears to be advantageous and more convenient to make the sample size smaller for the sake of easy carriage and storage of samples in field works.We have already reported on simple and rapid preconcentration methods for iron (II) 10 , manganese(II) 11 , and both thiosulfate and sulfite 12 in water using a SepPak C18 cartridge packed with C18-bonded silica, and that for phosphate 13 in water using a small column packed with zirconium-loaded activated carbon. These methods were successfully applied to environmental water samples as an in situ one, which were available at sampling sites. We have also developed a simple field determination of dissolved sulfide in environmental water samples using a lead-loaded chelating resin column. 14 Although this method was available for an in situ determination, its sensitivity and determination limit (0.5 mg sulfide-S/l) were not adequate for dissolved sulfide concentrations in environmental water samples, because this method was based on the length of a colored layer (lead sulfide layer) in a column proportional to the dissolved sulfide concentration in water.This paper describes a simple and rapid method for the in situ collection and preconcentration of dissolved sulfide in environmental waters. This method is based on the solid-phase extraction of Methylene Blue converted from sulfide, with Sep-Pak C18 cartridges, followed by a spectrophotometric determination. The Methylene Blue formation was based on the reaction of sulfide, iron(III) chloride, and N,N-dimet...
