Spatial-temporal variability of sulfide sulfur in the bottom sediments of the Sea of Azov
In 2014 and 2015 we obtained some data for the compositional analysis of the aquatic ecosystem of the Sea of Azov. Among the water chemical characteristics, the concentration of dissolved oxygen is of prime importance in assessing the environmental habitat of marine biological resources because it reflects production-destructive and dynamic processes in the marine environment. The analysis of our data has shown the relationship between the increasing concentration of sulfide sulfur in the sediments and the content of organic matter and the oxygen decrease in the near-bottom layer. The high content of sulfide sulfur in the sediments represents an imminent danger to aquatic organisms due to high toxicity of hydrogen sulfide.
