摘要

The PCBs and OCPs levels were investigated in sediment and zooplankton from Lake Hovsgol and soil and air in the settlement of Khankh, Mongolia. Total PCB congeners in zooplankton, sediments, air and soil from the Hovsgol Region comes to 0.993 ng/g WW, 0.36 ng/g DW, 96 pg/m3 and 7 ng/g DW, accordingly. It is possible that the presence of PCB in soil results from the using of PCB electrical equipment in past in the region. PCB congener pattern in zooplankton and sediment under the comparison with Lake Baikal indicate on atmospheric transport of PCB in the region at present. There is a possibility of modern entrance of some pesticides in the environment at present time. The additional studies of the distribution of POPs are needed for the region especially for terrestrial environment. The investigation was supported by RFFI-GFEN № 07-05-92116 and RFFI № 07-05-00697.
