摘要: Klavins, M., Silamikele, I., Nikodemus, O., Kalnina, L., Kuske, E., Rodinov, V., Purmalis,O., 2009. Peat properties, major and trace element accumulation in bog peat Latvia. Baltica, Vol. 22 (1), 37-49. Vilnius, ISSN 0067-3064. Abstract In this study the elements character of their peat, with a particular emphasis on properties impact local regional pollution sources ombrotrophic bogs Latvia, have been analysed. The values concentrations taken from 44 Latvia reflect processes mass indicating elements, apparently anthropogenic origin (Pb, Cd, Co, Ni others), upper layers profiles. addition they indicate several (for example, As, Cr, others) deeper bog, possibly due to feeding pattern, depending saturation groundwater. sorption capacity onto is influenced by proper- ties depends concentration oxygen containing functional groups growing an increasing degree decomposition humic/fulvic acid ratio humic matter. seems be largely unsaturated respect metal ions, but can correlated presence nitrogen ligands ratio.
