HEAVY METALS ACCUMULATION IN SOIL – PLANT SYSTEM IN POLLUTED ENVIRONMENT

Annotation

The objective of the paper was to study the patterns of zinc and lead translocation in the soil–plant system by the example of barley. Agrotechniques for crop cultivation are zonal. Experiments, observations, counts and plant sampling were carried out in accordance with the techniques of field experience. Contents of Zn and Pb were determined by atomic absorption spectrophotometry and X-ray fluorescence. According to the results of field experiments the differences in Zn and Pb distribution in organs of spring barley grown in unpolluted and apolluted (triple maximum allowable concentration) ordinary chernozem were established. Zn and Pb soil contamination results in a higher content of metals in all organs of barley. The main barrier function by inactivation of the investigated heavy metals is realized by plant roots. In subsequent years Zn and Pb translocation in plants reduced. However, there is a persistent contamination of plant products within three years after pollution. The tolerance of barley to Zn contamination was higher than to the contamination of Pb. The calculation of heavy metals accumulation coefficient is proposed to carry out taking into account all the mobile compounds in soil.
