Description
We investigated the basic soil types (brown, brown wood) of foothill zone of Dagestan. We revealed that the distribution of nickel, chromium and lead in the soils depends on several factors: soil-forming rock, physical clay, humus and pH. We defined the background content of heavy metals in the studied soils of the region

THE DIPOLE MOMENTS AND THE STRUCTURE OF THE FOUR-MEMBERED CLOSED-CHAIN ARSENIC COMPOUNDS
DescriptionBy the method of dipole moments, there has been determined that the tri-coordinated arsenic derivatives (p-XC6H4AsN-R)2 with R= Bu-t in the liquor exist in a cis-form, as for R=С6Н4Х-p the trans-structure is being realized. As for tetra-coordinated derivatives [XC6H4As(S)NBu-t]2 the trans-form is also beeing observed. For ortho-substituted connections, the angles of flat surfaces rotation of benzene rings have been defined
