Influence of soil type on accumulation and distribution of seven most toxic chlorinated biphenyls in carrot roots

Original language description

The extreme persistence of PCB in the environment and their ability to bioconcentrate in the food chain makes them great environmental and human health risk. The aim of this study was to investigate during two vegetation seasons the accumulation and distribution of seven most toxic PCB congeners (IUPAC No. 28, 52, 101, 118, 138, 153 and 180) in carrot roots (Daucus carota L. var. Nantes) grown on spiked soils (same amount of each PCB congener) with different physical and chemical characteristics. Results showed that the concentrations of the sum of PCB congeners (PCB7) in edible parts of carrot were significantly higher in the first experimental year. And also differences in PCB accumulation between treatments were observed only in the first year. Thehighest value 1280?130 ?g PCB7.kg-1 was found in carrot roots planted on the soil with the lowest soil organic matter content. The differences in accumulation of individual congeners were more obvious in the second year of plantation in t
