The influence of substances containing biogenic elements (potassium chloride, sodium phosphate, ammonium nitrate, potassium and urea nitrate) on phytoextraction degree of cadmium from soil by cultivated oat (Avena sativa L.), cutting lettuce (Lactuca sativa L.) and charlock (Sinapis arvensis L.) has been investigated. As the results of experiment the factors used for estimation of relationship between the environment and a physiological role of a chemical element, and also for revealing of its share in biotic turnover and of a role of organisms-indicators and organisms-concentrators have been calculated: phytotoxic effect and factor of biological absorbing of cadmium by plants. It is shown that potassium nitrate promote the extraction of cadmium from soil in a greater degree in comparison with other substances containing biogenic elements.ΠΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΎ Π²Π»ΠΈΡΠ½ΠΈΠ΅ Π²Π΅ΡΠ΅ΡΡΠ² , ΡΠΎΠ΄Π΅ΡΠΆΠ°ΡΠΈΡ

Influence of biogenic elements on cadmium phytoextraction from polluted soil
The influence of substances containing biogenic elements (potassium chloride, sodium phosphate, ammonium nitrate, potassium and urea nitrate) on phytoextraction degree of cadmium from soil by cultivated oat (Avena sativa L.), cutting lettuce (Lactuca sativa L.) and charlock (Sinapis arvensis L.) has been investigated. As the results of experiment the factors used for estimation of relationship between the environment and a physiological role of a chemical element, and also for revealing of its share in biotic turnover and of a role of organisms-indicators and organisms-concentrators have been calculated: phytotoxic effect and factor of biological absorbing of cadmium by plants. It is shown that potassium nitrate promote the extraction of cadmium from soil in a greater degree in comparison with other substances containing biogenic elements
The Level Of Anthropogenic Impact On Ecosystems As A Function Of Properties Of Plant Associations
The approach of estimation of a level of anthropogenic impact on ecosystems as a function of properties of plant associations has been proposed. In the course of investigation it was established that it is possible to estimate the growth degree of anthropogenic impact on ecosystem by: the increase part of a ruderal vegetation in common composition of plant associations; the increase amount of a ruderal vegetation growing on one square meter of soil surface (thickness of sowing); the increase of lead and cadmium content in above ground part of the plants. The sufficiently high ability of lead extraction from soil by such plants-accumulators as great nettle and meadow fescue has been establishe
