Bioaccumulation: terrestrial
Administrative data
- Endpoint:
- bioaccumulation: terrestrial
- Type of information:
- experimental study
- Adequacy of study:
- disregarded due to major methodological deficiencies
- Reliability:
- 3 (not reliable)
- Rationale for reliability incl. deficiencies:
- other: Data from a monitoring study. No correct analysis for total Mg concentration in soil (extraction with ammonium acetate-EDTA); Mg concentration in worms derived from graphs (average for all species present in a site).

Test organisms
- Details on test organisms:
- Earthworms collected in six sites along a gradient of urbanization, including Aporrectodea chlorotica, Aporrectodea caliginosa, Aporrectodea icterica, Aporrectodea rosea, Lumbricus castaneus, Lumbricus rubellus and Lumbricus terrestris
Test conditions
- Details on test conditions:
- Sandy loam soils; pH (H2O) 5.9-7.1, TOC 2.32-4.38%.
- Nominal and measured concentrations:
- internal Mg concentrations: 14500-16500 mg Mg/kg dry weight
Results and discussion
Bioconcentration factor
- Type:
- BSAF
- Value:
- 2.6 - 11.3 L/kg
- Basis:
- whole body d.w.
- Calculation basis:
- steady state
- Remarks on result:
- other: based on monitoring data of Mg concentration in worms and soil
Any other information on results incl. tables
Biota-to-soil -accumulation-factor (BSAF) were calculated as the ratio of the Mg concentration in worms (range 14500 -16500 mg Mg/kg dry weight) and the Mg concentration in soils (range 1103 -5640 mg Mg/kg dry weight) . The BASF range values are between 2.6 and 11.3.
Applicant's summary and conclusion
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
