Název v původním jazyce

Ability of Carrot (Daucus carota L.) to Accumulate Selected Polychlorinated Biphenyl Congeners

Popis výsledku v původním jazyce

Accumulation and distribution of seven indicator PCB congeners (IUPAC No. 28, 52, 101, 118, 138, 153 and 180) in carrots grown on spiked soils (100g of each PCB con-gener per kg of soil) with different physical and chemical characteristics were investigated during two vegetation seasons. Results showed that the concentrations of the sum of the tested congeners (PCB7) in edible parts of carrots were significantly higher compared to shoots. The differ-ences in PCB7 concentration in carrot roots among treat-ments were observed only during the first experimental year. The highest value, 1280 +- 130 ?g PCB7.kg-1, was found in carrot roots planted on the soil with the lowest organic matter content. The differences in accumulation of individ-ual congeners were more obvious in the second experimen-tal year, in terms of higher accumulation rate of more chlo-rinated biphenyls. The effect of soil type was not significant. In both years, congener profiles of all soils sampled after the harvest of
