Level in biota 

 

Human

Liver samples 0.1 to 1.72 ng/g fw (Ellerichmann et al 1998, IUCLID 5 section 7.10.5), which corresponds approximately to 1.3 to 39 ng/g lw

Fish: 

Arctic char from freshwater concentrations ≤ 1.8 ng/g lw (Norström et al 2004)

Perch concentrations from 15 to 37 ng/g lw (Norström et al 2004) and from 38 to 100 ng/g lw (Olsson et al 1999, Olsson & Bergmann 1995) and in the muscle 32 to 190 ng/g lw (Valters et al 1999)

Herring concentrations from 29 to 31 ng/g lw (Norström et al 2004)

Salmon concentrations from 7.8 to 33 ng/g lw (Norström et al 2004)

Marine Bird egg

White-tailed sea eagle eggs concentration 2.4 to 610 ng/g lw (Helander et al 2002) and 500 ng/g lw (Olsson & Bergmann 1995)

Guillemont egg concentrations 760 to 2600 ng/g lw (Jörundsdóttir et al 2006)

Herring Gull egg concentration not quantified (Letcher et al 1995)

Marine Bird tissues

Baltic guillemot muscle concentrations 1600 and 1900 ng/g lw (Norström et al 2004)

Marine mammals

Grey seal blubber tissue concentrations 41 to 210 ng/g lw (Larsson et al 2004)

Grey seal liver tissue concentrations 55 to 700 ng/g lw (Larsson et al 2004)

Grey seal lung tissue concentrations 21 to 98 ng/g lw (Larsson et al 2004)

Grey seal concentrations 49 to 480 ng/g lw (Norström et al 2004)

Remote areas 

 

5.24 to 143 ng/g lw plasma has been reported in biota (gull blood plasma) from the Norwegian Arctic, a remote area, proving its potential for long range transport (Verreault 2005). Further arctic MEC exist (Brown et al 2008)
