Toxicity to soil macroorganisms except arthropods
Administrative data
Link to relevant study record(s)
- 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:
- read-across source
- Key result
- Duration:
- 14 d
- Dose descriptor:
- LD0
- Effect conc.:
- >= 100 000 mg/kg soil dw
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mortality
- Key result
- 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).

- 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).

Additional information
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 (highest concentration tested, NERI 2008).
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 770 g/kg (highest concentration tested, LECES 1999).
