Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Relevant and reliable data that could be used for the determination of a PNEC for the freshwater environment - using the statistical extrapolation method - were retrieved for four different species: the frogs Xenopis laevis and Rana pipiens, the toad Anaxyrus fowleri (former name: Bufo fowleri), and the salamander Ambystoma maculatum. No-effect values ranged between 9.4 and 69.9 mg B/L, with the frog X.laevis. Depending on the species the assessed effect criteria were mortality, malformation or growth/reproduction. It should be noted that the values reported here here represent ‘added’ concentration levels and may therefore deviate slightly from values reported elsewhere.
No reliable long-term studies with additional marine aquatic organisms were identified in scientific literature.
Additional information
The identified reliable long-term data for additional aquatic organisms were used for the determination of a PNEC for the freshwater environment - using the statistical extrapolation method. All reported effect levels were generated with either boric acid or disodium tetraborate decahydrate as test substance, and test concentrations in the test media were verified.
The effect criterion for the salamander A.maculatum was malformation. Mortality was the main criterion for the three other species. Growth and reproduction were also assessed for the frog X.laevis, but were as sensitive as mortality.
Additional information on the different long-term studies with invertebrates can be found in the Tables and in the Background Document “Environmental effects assessment of boron”, which is attached in the technical dossier in IUCLID Section 13.
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.
