The paper present result of research on the intensity of the absorption of lead from the soil by plants barley. The object of the study were plant spring barley varieties Peas in various stages of development. Lead was added to the soil (dark–grey podzolic) as a Pb(CH3COO)2 in the concentration of 32, 160 and 320 mg Pb+2 per kg of the soil. Lead is one of the heavy metals which occur in the environment as a result of antropogenic activities.
Established that the lead content in barley amended as follows: underground faction> vegetative biomass fraction> generative fraction. Lead absorbed most intensive barley in the flowering stage.
The effect of Pb and other heavy metals on plants depends not only on its form, but also on the presence and concentration of other elements and substances, the plant species and its developmental stage are also important. Several soil conditions,such as the pH value, calcium level, content of organic substances, particulaly humus etc., are decisive for the exchangeable and water soluble, available Pb for plants.
