Abstract:

The basic regularities of the distribution of heavy metals’migration pedogeochemical barriers in soil profile of the chernozems ordinary and southern at Kryvy Rih mining and metallurgical regions were analyzed. It was pointed out that heavy metals’migration pedogeochemical barriers is a part of the soil horizon or soil profile, where there is a significant concentration of individual chemical elements as a consequence of the substitution-reaction phenomenon. Pedogeochemical barriers are classified into five types: mechanical, physical, physical and chemical, chemical and biological. The spread

The aims of this study were to consider the genesis’s idea «geochemical barriers» and to invite a definition for «pedogeochemical barriers» by example of heavy metals’ migration. Object of this study – scientific publications that show the results of heavy metals’ content and distribution in soils. The concept of geochemical barriers was formulated by A. I. Perelman in 1961. At first ideas of this concept have been used for: 1) ordering of the geochemical conditions at hypergenesis zone, 2) justification the concept of geochemical field; 3) mathematical modeling of geochemical processes, 4) ef

Abstract:

Abstract Background The use of rock powders in soil has emerged as a nature-based technology to improve soil properties relevant to crop development and for atmospheric carbon dioxide removal (CDR) via enhanced rock weathering (ERW). Although modeling this process is crucial, the soil microbiome has been identified as the main reason why several experimental and field results do not fit the geochemical and kinetic theoretical models. Here, the hypothesis that the bacterial community structure is modulated by the application of different silicate rock powders was tested. One phonolite, three ba

Abstract:

O comportamento do U e do Th foi analisado durante a evolução pedogeoquímica e morfogenética de paisagens tropicais úmidas, sobre rocha granítica com teores normais desses elementos, visando estabelecer relações entre rocha-mãe e anomalias de U e de Th, tipos de solos residuais e geoformas resultantes dessa evolução. Em uma vertente caracterizada pelo sistema de transformação Latossolo-Solo Podzólico, anomalias de U e de Th de grande expressão geográfica e intensidade ocorrem na paisagem eluvial, parte superior da vertente onde se verificam declividades entre 0 e 8%. Tais radioanomalias são de

Abstract:

Foram estabelecidas e analisadas as principais relações entre intensidades de exalação de radônio ( 222Rn e 220Rn) e os elementos morfológicos e dinâmicos de paisagens tropicais úmidas, com o objetivo de elaborar modelos de exalação de Rn adaptados a este tipo de paisagens, e aplicáveis na escala de pequenos núcleos habitacionais. Em uma vertente sobre rocha granítica com teores normais em U e Th, e caracterizada pela associação Latossolo-Solo Podzólico, os produtos de atuação dos processos supergênicos, com destaque para a transição de latolização em podzolização, e o atual regime hídrico do
