The heavy metals content in tissues of some pedobiontie, herpetobionte, hortobionte organisms from natural biogeocenoses, agrobiocenoses, and urban ecosystems has been evaluated. Spreading, migration, circulation and bioaccumulation of heavy metals depend on a complex of environmental factors (temperature, humidity, solar radiation) of habitat, the level of quantitave bioaccumulation of the metalic macroelimentes in nutrition, pecularities of age and dimenssional ones, respiration intensity, rate of reproduction, number of generations of invertebrate animals. The heavy metals content (mcg /gr of the dry mass) in tissues of some ecologo-taxonomic groups of herpetobiontic, hortobiontic, pedobiontic organisms of Lumbricidae family was evaluated: Cu-1,37, Cd-0,18, Zn-0,96, Pb-1,41, Cr-0,19, Mn-7,13, Ni-0,12, As-0,97, V-0,89., Isopoda Cu-0,98, Cd-0,09, Zn-,0,72, Pb-0,88, Cr-0,11, Mn-4,4, Ni-0,07, As-0,56, V-0,07., Chilopoda Cu-0,78, Cd-0,05, Zn-0,61, Pb-0,69, Cr-0,07, Mn-5,51, Ni-0,03, As-0,51, V-0,03., Diplopoda Cu-1,01, Cd-0,07, Zn-0,71, Pb-0,99, Cr-0,08, Mn-5,7, Ni-0,06, As-0,60, V-0,05., Carabidae Cu-1,25, Cd-0,12, Zn-0,80, Pb-1,17, Cr-0,16, Mn-6,85, Ni-0,07, As-0,82, V-0,77., Staphylinidae Cu-0,84, Cd-0,04, Zn-0,76, Pb-103,, Cr-0,10, Mn-4,87, Ni-0,05, As-0,48, V-0,24., Elateridae Cu-1,02, Cd-0,12, Zn-0,58, Pb-0,87, Cr-0,12, Mn-5,77, Ni-0,03, As-0,30, V-0,06., Tenebrionidae Cu-1,11, Cd-0,10, Zn-0,61, Pb-0,95,Cr-0,14, Mn-5,91, Ni-0,05, As-0,53, V-0,07., Tardigrada Cu-1,29, Cd-0,15, Zn-0,87, Pb-1,26,Cr-0,18, Mn-7,10, Ni-0,11, As-0,90, V-0,88., Gastropoda Cu-1,32, Cd-0,26, Zn-1,95, Pb-1,35,Cr-0,22, Mn-8,05, Ni-0,20, As-1,03, V-0,17.,Pentatomidae Cu-1,13, Cd-0,13, Zn-0,87, Pb-1,19,Cr-0,16, Mn-5,75, Ni-0,14, As-0,85, V-0,55., Coccinellidae Cu-0,74, Cd-0,05, Zn-0,56, Pb-1,10,Cr-0,19, Mn-4,12, Ni-0,07, As-0,39, V-0,09., Cantharidae Cu- 0,90, Cd- 0,07, Zn-,0,48, Pb-0,82, Cr-0,12, Mn-3,35, Ni-0,03, As-0,28, V-0,06., Aranei Cu- 0,71, Cd-0,04 , Zn-0,39, Pb-0,84, Cr-0,04, Mn-3,22, Ni-0,04, As-0,45, V-0,02., Tubificidae Cu- 1,56, Cd-0,12 , Zn-1,14, Pb-1,31, Cr-0,17, Mn-8.80, Ni-0,19, As-0,90, V-1,10, Chironomidae Cu-1,40 , Cd- 0,16, Zn-1,06, Pb-1,19, Cr-0,17, Mn-7,39, Ni-0,14, As-0,99, V-1,08. Heavy metal ions bioacumulation in tissues of the invertebrate animals unsettles biochemical, morphological, physiological proceeses (respiration intensity, transpiration), metabolism, permiability of nutritive substances, and of oxygen into membrane of the celular layer, and of the neurosecretory system, hydric, lipid metabolism, as well as unsettles the fermentative, nutritive processes.
