The influence of the (V) sodium arsenate on the content of the free and bound amino acids of the soil dissolved organic matter

In the laboratory experiment the influence of (V) sodium arsenate on the quantitative composition and qualitative content of free and bound amino acids of the dissolved organic matter in the dark-gray forest soil is established. Depending on the As(V) introduction dose, the free amino acid content varied from 53,0±7,5 to 240,2±53,7 microgram/kg, the bound amino acids content varied from 106,9±13,9 to 527,5±93,4 microgram/kg. The amino acidquality composition in the arsenic contamination didn’t change.
