It is shown that the lipid fraction of soil organic matter consists of molecular fragments of aliphatic, O,N-alkyl, aromatic, and carboxyl groups, chlorophyll and/or chlorophyll-like pigments. The 13C-NMR data show that an increase in the degree of hydromorphism leads to an increase in the proportion of unsaturated components (-C=C-; -Ar). The paramagnetic… (More)
Functional groups and molecular fragments are identified and quantified and the paramagnetic activity of humic substances is assessed. It is shown that, compared with fulvic acids, humic acids have fewer oxygen-containing functional groups and more aromatic structures.
This work surveys the genetic toxicity of benzo(a)pyrene added to soil for Tradescantia plants (clone 02). Different adaptation levels of Tradescantia (clone 02) to soil pollution with benzo(a)pyrene have been estimated. Plant adaptation was not observed at the morphological level, but found for the physiological and genetic (with every adaptation stage)… (More)
Molecular weight distribution of humic and fulvic acid preparations extracted from podzolic, peaty podzolic weakly gleyed, and arable soils is investigated. The effect of the agricultural use of soils on the fractional composition of humic compounds is assessed.
