Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
Environmental levels
Air:
The concentrations reported are 0.3 to 0.05 ng/m³ in the air (Arnér et al 2004).
Soil & Sediments
Soils:
No MEC available
Freshwater lake sediments:
MEC > LOD (level of detection) being 0.01 mg/kg dw (Haarstad & Borch 2004)
River Sediment from contaminated site:
MEC > LOD in the order of 10 mg/kg dw (Swindlehurst et al 1995)
Sewage sludge:
MEC > LOD in the order of 2 mg/kg dw (Arnér et al 2004).
Water:
River delta marine water:
MEC 0.18 to 2.2 ng/L (Bester et al 2001)
River water:
MEC > 30 ng/L Somes River (Moldovan 2006)
MEC river water > 10 ng/L (Müller et al 1997)
Ground water:
MEC > 100 ng/L (Arnér et al 2004)
Leachate :
MEC > 100 ng/L (Arnér et al 2004)
Sewage water:
MEC = 4000 ng/L in untreated fraction (Arnér et al 2004), no value reported from treated water fraction
Lakewater:
MEC > LOD (Guzzella & Sora 1998)
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)
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
