The first data on content of inorganic reduced sulfur compounds [H2S, S°, S2O3(2-), SO3(2-)] were obtained at two stations in the northeastern Levant Sea (Mediterranean Basin). With lower detection limit for the mentioned sulfur forms of 30 nM, sulfide forms were not found, while thiosulfate concentration varied from 178 to 890 nM (from 24 to 78 % of total reduced S), and S° varied from 156 to 1090 nM. Vertical distribution of these compounds showed irregular character; correlation between total reduced S maxima, fluorescence, and increase of nutrient element content near the lower pycnocline boundary was observed. The maximum total sulfur concentration in the surface layer was likely due an anthropogenic influence. The ''starting'' mechanism that controls appearance and distribution of sulfur compounds in oxygen-containing water is the process of bacterial sulfate reduction in micropatches of fresh organic detritus. Reduced sulfur forms participate further in a series of chemical and biochemical processes. Contribution of hydrolysis of organic sulfur-containing compounds is insignificant for the region in study.
