Abstract
Recently, contamination of soils and groundwater is becoming a social concern in our country. Phytoremediation will be becoming one of the choices in the remediation technology. Phytoremediation is divided into four functions: phytodegradation, phytovolatilization, phytoextraction, rhizofiltration. In this paper, we tested applicability of turnip Brassica rapa for phytoextraction. Two experiments were done. The results showed that the turnip has an ability to accumulate cadmium and copper of low concentrations, like presented conditions, and that during growth, plants seemed to be less sensitive to cadmium and copper toxicity. According to the cadmium distribution, roots of turnip could extract cadmium from soils.
