Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Endpoint:
toxicity to soil macroorganisms except arthropods: short-term
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Justification for type of information:
The available identification data for the Target and the Source substance support the read-across hypothesis. Adequate, reliable and available scientific information indicate that the Target and Source substance have, or are very likely to have, similar (eco)toxicological properties. There are no indications that constituents other than those identified for the substances or impurities may influence the validity of the read-across. There is no evidence that additional toxicological mechanisms, other than those identified in the read-across hypothesis, may be acting or have an adverse effect on the validity of the read-across.
Reason / purpose for cross-reference:

Duration:
14 d
Dose descriptor:

Effect conc.:
>= 100 000 mg/kg soil dw
Nominal / measured:

Basis for effect:

Duration:
14 d
Dose descriptor:
LC50
Effect conc.:
> 100 000 mg/kg soil dw
Nominal / measured:
meas. (initial)
Conc. based on:
test mat.
Basis for effect:
mortality
Validity criteria fulfilled:
yes
Remarks:
The positive control substance, carbendazim, affected the Eisenia fetida population significantly, efficiently killing the worms
Conclusions:
ABS: Eisenia fetida OECD 207: 14 d-LC0 = 100 g/kg (highest concentration tested)
Executive summary:

In an earthworm acute toxicity test performed according to OECD 207 and GLP, powdered air-cooled blast furnace slag (ABS) did not affect survival or body fresh weight of the earthworm Eisenia fetida during 2 weeks incubation in soil with a maximum concentration of 100 g of the slag per kg of artificial OECD soil (NERI 2008).

Conc. based on:

Basis for effect:
mortality
Validity criteria fulfilled:
yes
Conclusions:
ABS: ISO 11268-1, Eisenia fetida: 14 d-LC50 = 560 g/kg
Executive summary:

The effects of slags on earthworms were measured in a 14 d test according to ISO 11268-1 (Effects of Pollutants on Earthworms. 1. Determination of Acute Toxicity Using Artificial Soil Substrate). ABS was not toxic against Eisenia fetida within 14 days. The LC50 was 560 g/kg soil (LECES 1999).

Description of key information

ABS: Eisenia fetida OECD 207: 14 d-LC0 = 100 g/kg (highest concentration tested)
ABS: Eisenia fetida ISO 11268-1: 14 d-LC50 = 770 g/kg (highest concentration tested)

ABS: ISO 11268-1, Eisenia fetida: 14 d-LC50 = 560 g/kg

Key value for chemical safety assessment

Short-term EC50 or LC50 for soil macroorganisms:
770 000 mg/kg soil dw
