Abstract: | The O.E.C.D. monitoring Wildlife Sampling and Analysis Programme 1973–1975 has been extended at national level in Finland to 1978 by analysing chlorinated hydrocarbon residues in fish at two marine and two freshwater environments and mercury at the latter two freshwater environments. Statistical treatment of the analysis results gave significant decreasing trends in most cases of PCB and DDT residues but in mercury levels no significant change was detected. |
