Sandimirov S. Screening studies of POP levels in bottom sediments from selected lakes in the Paz watercourse / In State of the environment in the Norwegian, Finnish and Russian border area. The Finnish Environment. Finland, Jyvaskyla: Kopijyva Oy. 2007, №6.

Screening studies of PO P levels in bottom sediments from selected lakes in the Paz watercourse Table 5 summarize the result o f PCB analyses in bottom sediment samples. Geographical distribution o f total PCBH concentrations is shown in Figure 7. Table 5. Polychlorinated biphenyls (PCBs) (ng/g dry weight) in bottom sediments. TCDD-equivalents (TEQ pcb ) (pgTEQ/g dry weight) are calculated using toxic equivalencyfactors (TEFs) according to the WHO International Program on Chemical Safety (IPCS) model (Ahlborg et al., 1994). Non-ortho and mono-ortho substituted CB congeners are marked by boldfont.
