摘要

One of the important aspects for remediation of contaminated soils is a reduction of biological mobility of radionuclides in the water-soil-plant system. Anthropogenic radionuclides ~(137)Cs and ~(90)Sr become more concentrated as they move up the food chain often becoming human health hazards. The aim of the research is to elucidate the influence of polymers' impact on biological migration of ~(90)Sr and ~(137)Cs in the system irrigation water-soil-plant in zones of radioecological tension. The tests were carried out in soil without and with application of polymer Ca" in root-inhabited media (RIM) in the most radioecological tension zone of Armenia. Sweet basil (Ocimum basilicum L.) was chosen for the investigations. Both quantitative and qualitative productivity of basil depending on (1) the presence or absence of Ca~(++) polymer, (2) quantity of Ca~(++) polymer, (3) content of artificial radionuclides in different soil layers and (4) type of plant tissue were determined. The presence of Ca~(++) polymer in soil RIM promoted the decrease of ~(90)Sr content in basil leaves 1.7-2.0 times compared to the control sample. The use of 1 g/plant Ca~(++) polymer decreased the content of artificial radionuclides in the soil layer at the end of vegetative period: 1.5 times for ~(90)Sr and 1.3 times for ~(137)Cs. Ca~(++) polymer was effective for decreasing ~(90)Sr concentration in sweet basil.
