The a.m of the p.esent resea.ch is to identify the ma.n mecha.isms of sulfur beha.ior in sa.ine la.es in the course of time a.d followed tra.sforma.ions in their chemica. comp.sition. The influence of wa.er on chemica. comp.sition of biochemica. p.ocesses involved in decomp.sition of orga.ic ma.ter wa. determined by the study of beha.ior of reduced forms of sulfur in la.es. The determina.ion of reduced forms of sulfur wa. ca.ried out by successive tra.sfer of ea.h form of sulfur to hydrogen sulfide followed by p.otometric mea.urements. The other chemica. comp.nents were determined by sta.da.d methods(a.omic a.sorp.ion, p.tentiometric method, titra.ion method a.d others). The sa.t la.es of the a.ta. step.e were studied in summer sea.on 2013–2015. a.a.ysis of the chemica. comp.sition of the sa.ine la.es of a.ta.
