Figure 2

PCBs, PFCs, and PBDEs in herring gull eggs from three ESB locations in German coastal waters. Given are the mean concentrations of PCB (sum of congeners 28, 52, 101, 118, 138, 153, 180), seven PFCs (sum of PFOA, PFNA, PFDA, PFUnA, PFHxS, PFHpS, PFOS), and PBDE (sum of 35 congeners 1, 2, 3, 7, 10, 13, 15, 17, 25, 28, 35, 47, 49, 66, 71, 75, 77, 85, 99, 100, 116, 119, 126, 138, 140, 153, 154, 155, 156, 181, 183, 197, 203, 207, 209). For values below the detection limit, a default value of 0.5 of the respective detection limit was included. 1988 to 1992: mean concentrations of the years 1988, 1990, and 1992; 1998 to 2001: mean concentrations of the years 1998, 2000, and 2001; 2006 to 2008: mean concentrations of the years 2006, 2007, and 2008; 1993 to 1998: mean concentrations of the years 1993, 1996, and 1998; 2001 to 2003: mean concentration of the years 2001, 2002, and 2003.
