Özet

The city of Izmir on the Aegean Sea shoreline is suffering from rotten odors emitted by anoxic river mouths. Anaerobic conditions in the shallowest portion of Izmir Bay due to industrial and domestic wastewaters as well as eutrophication products in this very calm part of the Bay are responsible for this. The inner section of the Bay is becoming shallower with sediments rich in organic matter. Aerobic digestion of organic pollutants is limited by the oxygen input and the warm climate leads to an optimal medium for anaerobic processes when anoxic conditions take over. Anaerobic digestion products are odorous gases among which H2S with a characteristic pungent odor is most effective in this case. Sulfur containing gases are formed from sulfides and sulfates in the sediment-water interface and are released into the air. Airborne H2S concentrations are variable as they depend on factors such as high atmospheric diffusion coefficients under changing wind direction and speed, as well as variable such as water depths, organic loadings from rivers, air and water temperatures, sulfate concentrations in sediment and water phases, pH, and Eh.
