Title:	Decreasing trend of persistent organic pollutants (POPs) in herring from the southern Baltic Sea
Authors:	Sapota Grażyna
Abstract:	The aim of this work was to examine the level of POPs (DDT and its metabolites, isomers of HCH, HCB and PCBs) in pelagic herring (Clupea harengus) caught in the southern Baltic Sea once a year during the period 1998-2003. Historical time trends of POPs from the 1970s to the year 1998 were calculated on the basis of the HELCOM Database. The measurements executed within Integrated Monitoring Programme of the Baltic Sea Environment HELCOM/COMBINE confirm that declines in the levels of PCBs and DDT have occurred in some fish from the Baltic Sea over the past 30 years. In herring muscle PCBs have decreased to about 15% of levels of the early 1970s and DDT to 5% of 1970s levels.
