(22) Two stored forms of [H.sub.2]S have been identified: acid-labile sulfur and bound sulfane sulfur.
Does bound sulfane sulfur release enough [H.sub.2]S with appropriate timing for the exertion of [H.sub.2]S activity?

There are many ligands used on the cloud point extraction/preconcentration of lead reported in the literature, such as methyl-2-pyridylketone oxime (MPKO) (GHAEDI et al., 2008), dimethylglyoxime (DMG) (BAKIRCIOGLU, 2012), 1-(2-thiazolylazo)2-naphthol (TAN) (CHEN; TEO, 2001; SILVA; ROLDAN, 2009), bis((1H-benzo [d] imidazol2yl)ethyl) sulfane (BIES) (GHAEDI et al., 2009), dithizone (WEN et al., 2012), O,Odiethyldithiophosphate (DDTP) (BORGES et al., 2003; MANZOORI; BAVILI-TABRIZI, 2002) and 2-(5-bromo-2-pyridylazo)-5-(diethylamino)-phenol (5-Br-PADAP) (CHEN et al., 2005).
In this process, the deposits of inorganic materials in the peat bogs were submitted to the influence of humic acids and decomposition products of the vegetable matter: carbon dioxide, sulfane, ammonia and hydrogen.
[H.sub.2]S can store its sulfur group with iron (acid labile sulfur) [15] or in sulfane sulfur (a persulfide) [16] in mammalian tissues.
In the past years, a growing body of evidence suggests a concept by which intracellular [H.sub.2]S concentrations are determined by (1) its enzymatic production; (2) its intracellular storage as bound sulfane sulfur; and (3) its oxidative degradation by mitochondria.
