The article considers biogeochemical features of arsenic (As) in grassy plants
and shrubs of natural geochemical anomaly in the Zabaikalsky krai. The study shows
that different kinds of plants possess unequal ability to absorb it. Such kinds of plants as
Aconogonon angustifolium and Artemisia gmelinii accumulate arsenic without any barrier.
Aconogonon angustifolium can accumulate about 847, 3 mg / kg, and Artemisia gmelinii
- up to 138, 5 mg / kg of arsenic. Concentration of this element can considerably differ
in separate organs. Its maximal concentration is in the roots and leaves and the minimal
is in flowers, inflorescences and fruits. The authors of the article distinguish four classes
according to its concentration level in the plant. The critical concentration of arsenic is
mostly found in the roots and leaves. The absence of this element in the fruits and seeds
suggests that there are barriers which prevent its accumulation in these organs.
