Organochlorine Pesticide and Trace Metal Monitoring of Russian Rivers Flowing to the Arctic Ocean: 1990-1996

摘要

Information is presented on the concentrations of orga- nochlorine pesticides (HCHs and DDT residues) and trace metals (Fe, Cu, Zn and Ni) in waters of 15 large Russian rivers flowing to the Arctic Ocean during 1990-1996. Estimates of the corresponding annual flexes are made. Other contaminants (hg, Pb, Cr, mn, β-HCH and di- Hydroheoptachlor) were examined briefly. Concentration Data are presented as averaged annual means for each of The seven years with the ranges, standard deviations and Numbers of samples.
