Reason of the choice of soil types for hygienic regulation of chemicals (literature review)

Abstract

The article discusses a functional-ecological approach to the selection of soils for the purpose of hygienic regulation of chemicals. The functional-ecological approach used to substantiate the choice of soil types in standardization is associated with the analysis of their main, variable functional characteristics including humus state, particle size distribution, oxidizing capacity, sorption capacity, cation exchange capacity, etc. The choice of the type of soil can be made using the data on the classes, distinguished by the parameters of the stability of the functioning of the soils. The approach will allow making a rational choice of soils from all their diversity. According to the degree of stability and development, it is proposed to use contrasting options for soils, taking into account the area they occupy. The functional-ecological approach does not imply the choice of a specific soil characteristic, but takes into account the cumulative assessment of all soil properties according to the principle of their sustainability. In addition, it is advisable to create a network for hygienic rationing and maintain a database of the results obtained throughout the country. The main databases for the literature search were Scopus, Web of Science (WoS), Global Health, CyberLeninka, scientific electronic library elibrary.ru (RSCI). Since this topic affects the formation of an approach in the guidelines for determining the maximum permissible concentration, the review publication included information on National Russian standards, educational (national Atlas of soils of the Russian Federation, WRB - World Reference Base of Soil Resources) and scientific literature.
