Polysulfides (Sx2−) are sulfide oxidation intermediates that are important for a variety of
environmentally relevant processes including pyrite formation, organic matter sulfidization …

Cyanate can serve as a nitrogen and/or carbon source for different microorganisms and as
an energy source for autotrophic ammonia oxidizers. However, the extent of cyanate …

Background The paper presents a quantification of main (hydrogen sulfide and sulfate), as
well as of intermediate sulfur species (zero-valent sulfur (ZVS), thiosulfate, sulfite …

The presence of organic molecules containing sulfur-sulfur bonds was documented in the
water columns and sediments of the natural aquatic systems as well as in fossil fuels. These …

Background We studied the annual variability of the concentration and isotopic composition
of main sulfur species and sulfide oxidation intermediates in the water column of monomictic …

Intertidal flats are highly productive coastal marine ecosystems which are affected by fast
changes in environmental conditions and host dynamic biogeochemical cycles in their …

Rates of thiocyanate degradation were measured in waters and sediments of marine and
limnic systems under various redox conditions, oxic, anoxic (nonsulfidic, nonferruginous …

Gold mining in Asia utilizes cyanide to extract gold from ores, and the resulting cyanide-
contaminated mine tailings are disposed of in a tailing storage facility (TSF). Nevertheless …

Cyanide (CN) is a rapidly acting chemical which occurs in many forms, the most toxic and
common of which are free cyanide (CN-) and hydrogen cyanide or hydrocyanic acid (HCN) …

Reactions between cyanide and compounds, which contain S–S bonds, in aqueous media
result in formation of thiocyanate. In this work, we studied the kinetics of reactions of …
