Budgets of Pb and Cd in soils and critical time to reach a harmful level

Popis výsledku v původním jazyce

Heavy metals in soils can be hazardous to ecosystems. Budgets of Pb and Cd in agricultural soils are presented. The concentrations of the heavy metals are presente as a function of time. A critical time is set when the concentrations of the metals reacha level critical to an ecosystem. The predicted temporal trends in Cd and Pb concentrations in agricultural soils of polluted central Europe are compared less polluted regions. While the critical concentration of Cd is reached in about sixty years in theCzech agricultural soils, the data from Sweden indicate that Cd is being depleted from the forest soils so that the critical upper level will never be reached. A critical concentration of lead in soil will be reached in about one thousand years in the Czech Republic, while the critical concentration will never be reached in the Swedish forest soils at present atmospheric deposition and agricultural inputs.
