Water-soluble species of some macro- and microelements in the soils of the urbanized territories of the Moscow region |
|
|
The paper presents the results of studying the concentration of water-soluble forms of macro- and microelements by flame photometry, potentiometry and mass spectrometry with ionization in inductively coupled plasma in 30 soil samples taken in roadside and intended for building areas of the Moscow region. The possibility of using triple content diagrams of water-soluble forms of Na-K-Ca to study the specifics of soil salinization is shown. It was revealed that the degree of provision of the studied soils with potassium varies from very low to high. Soils do not accumulate water-soluble forms of fluoride - and chloride - ions, as well as Mn, Co, Zn, Mo, Cd, Sb, and Pb, but they accumulate copper in concentrations up to 3.5 maximum permissible concentration.
