Whenever environmental pollution by sulphur compounds is under discussion, the latter contemplate those compounds that may be subjected to consideration through the employment of methods of analytical control. First of all, sulphates and volatile compounds of partially or completely restored sulphur, such as SO2, H2S, methyl sulphur compounds (merkaptans, dimethyl sulphide, dimethyl disulphide and others) may be subjected to control. Elementary sulphur that is contained in the water is difficult to analyze. At the same time, an extensive group of water-soluble compounds of restored sulphur is not considered by numerous nature protection organizations. As a rule, they do not possess distinct analytical properties. The latter include any organic and inorganic thio-acids and their combinations with ions of transitive metals, in particular, with ions of monovalent copper. Microcolloidal (nano-) particles of FeS may also be included into this group of compounds. The objective of the article is to generate the awareness of those compounds of reduced sulphur that are out of control. By virtue of this article, the authors apply to specialists in water treatment, water conditioning and water quality regulation.
