Reaction of the environment and content of heavy metals in alluvial soils in the plain of the river Big Yugan

The article deals with the regularities of accumulating of heavy metals and biologically active agents (photosynthesis pigments) in inundated types of meadow plants. Research was conducted in four plant communities: a mixed herbs-cereal shrubby meadow, a mixed-herbs-canary shrubby meadow, an aspen forest shrubby meadow, an osier-bed sedge in the neighborhood of the village of Yugan, Surgut District, Khanty-Mansiysk Autonomous Area - Yugra. Collection of plants was made for determination of the content of photosynthetic pigments (chlorophylls a, b, carotinoids) and heavy metals on the trial areas. 7 types of plants served as an object of our research: Calamagrostis purpurea (Trin.) Trin., Carex acuta L., Carex aquatilis Wahlenb., Carex vesicaria L., Carex rostrata Stokes., Elytrigia repens (L.) Desv. ex Nevski, Phalaroides arundinacea (L.) Rausch. In plant communities we conducted the sampling of the studied plants (roots, leaves) and also soil sampling was made. Roots of plants were cleared from soil and washed in flowing water...
