Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Toxicity to soil macroorganisms except arthropods

- Endpoint:
- toxicity to soil macroorganisms except arthropods: long-term
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Justification for type of information:
- Soil hazard category of the registered substance was determined in accordance with Table R.7.11—2 of ECHA Endpoint specific guidance Chapter R.7c (Version 3.0 – June 2017).
- BPA PO was found to be inherently biodegradable and is therefore not considered as being highly persistent.
- BPA PO has a Log Kow < 5 and was not identified as an ionisable substance, therefore it does not have a potential for high adsorption.
- BPA PO was not identified as very toxic to the aquatic organisms, as EC50 and LC50 values for algae, fish, and aquatic invertebrates were above 1 mg/L.
Based on these criteria it was concluded that the registered substance falls into Hazard category 1.
As the substance belongs to Hazard category 1 according to Table R.7.11—2, the equilibrium partitioning method has been applied to derive the PNEC for soil and to assess the hazard to soil organisms. As all risk characterization ratios for hazards to soil are under 1, therefore no further testing is proposed for toxicity to soil macroorganisms in accordance with ECHA Endpoint specific guidance Chapter R.7c (Version 3.0 – June 2017).

Description of key information
Based on the properties of the substance and the criteria laid down in Table R.7.11—2 of ECHA Endpoint specific guidance Chapter R.7c (Version 3.0–June 2017), it was concluded that the substance belongs to hazard category 1 in regards to its hazard to soil. Therefore the equilibrium partitioning method has been applied to derive the PNEC for soil and to assess the hazard to soil organisms. As all risk characterization ratios for hazards to soil are under 1, therefore it is not required to perform toxicity testing on soil macroorganisms in accordance with ECHA Endpoint specific guidance Chapter R.7c (Version 3.0–June 2017).

Additional information
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.
