The impact of anthropogenic impact on the chemical composition Dаctylis glomerаta

Elcheva I., Zubkova V.

The article presents data on the content and migration of heavy metals (HM) in the soil-plant system on the example of Dactylis glomerata in order to establish the degree of ecological balance in the urban district of Istra. It was found that the accumulation of HM in plants is determined primarily by the type of element, its biofilm and occurs by acropetal type. The content of individual elements in plants depending on soil conditions changed in 1,1-48,9 times. Given the bioecological features of Dactylis glomerata in the accumulation of TM, low coefficients of their biological absorption, it can be recommended for use in feed production.
