Актуальные вопросы бриоиндикации в условиях Донбасса

Abstract

For the first time in the territory of Donetsk region, content of the elements (Pb, Zn, Cu, Ni, Mn, Fe, Cr, Ca, Sn, Cd, Mo, Sb) has been fixed by means of roentgenofluorescence in gametophytes of Bryum argenteum Hedw. and Bryum caespiticium Hedw. mosses and in soils as a result of anthropogenic impact of various intensity degree. It has been determined that B. argenteum accumulates the bigger element mass than B. caespiticium. Comparatively to maximum allowable concentration and regional background, such elements as Pb, Ni, Sn and Sb are accumulated in insignificant amounts. The results obtained are indicative of the possibility of bryophitic plants usage as test-species of environment pollution.
