Phytoremediation process for the removal of ¹³³Cs from soil

INTRODUCTION

The soil pollution is an issue of considerable

pollution of soil is more long-term problem with chronic consequences

1

GOALS

Evaluation of different aquatic and terrestrial plants ability to accumulate cesium and consequently assessed their applicability in phytoremediation.

1

Evaluate bioconcentration potential of different parts of plants to accumulate Cs. Assessed the role of leafs and roots in removal of Cs from contaminated medium.

Phytoremediation process for the removal of ¹³³Cs from soil

Today other several techniques have been proposed and used, of which one is the phytoremediation

PHYTOREMEDIATION ³

CESIUM

Cesium (Cs) is chemically similar to potassium (K). However, although K is an essential element, Cs is toxic to plants.

- ¹³⁷Cs radioactive isotope

- ¹³³Cs stable isotope

Phytoremediation process for the removal of ¹³³Cs from soil

METHODOLOGY

The work was conducted at Czech University of Life Sciences Prague, Faculty of Environmental Science.

1) Preparation of the plants for the experiment;

2) Experiment – Exposition of plants to cesium;

3) Analyses of Cs in plants.

The experimental part of the thesis was conducted in three main steps:
