- A short summary of the results up to year 2002/03 is given below. Graphical presentations,tables and details are given in the following chapters. A summary of the estimatedconcentrations up to 2002/03 is given in table 23.3.•The condition of herring in the Baltic is decreasing in almost all autumn time series. Atthe same time fat content is decreasing in herring from Harufjärden, Landsort andUtlängan (autumn and spring).•Lead concentrations in herring, cod and perch livers are decreasing in almost all timeseries from both the Swedish west coast and the Baltic.•The increasing trends of cadmium concentrations in herring liver from the Baltic Properand from the Bothnian Sea reported for the period 1980 to 1997 seems to havestopped.In herring from Ängskärsklubb a significant decrease can be seen for the last ten years,and in the time series from Landsort there is also indications of this decrease.•Cadmium concentrations in blue mussels from the Baltic Proper are about 5 timeshigherthan the suggested background levels for the North Sea and 3 times higher thanthe mussel samples from Fladen and Väderöarna.•HCH’s are decreasing at almost all sites with a time serie long enough to permit astatistical trend analysis.•HCB is decreasing in herring, cod and guillemot from the Baltic Proper and also inherring and cod at the Swedish westcoast. However, some relativelyhighconcentrationshave been detected in the last years, and it looks like the decrease islevelling out.•TCDD-equivalents have not decreased in herring at Harufjärden, Karlskrona andFladen during the investigated timeperiod 1990-1999. There is a significant decrease ofthese substances in guillemot eggs from St Karlsö between 1970 and the middle of the80-ies after that, the decrease has levelled out.
