Additional information
The long-term aquatic toxicity of Boron in invertebrate was evaluated in a earl-life stage toxicity test performed equivalent to EPA US EPA 2000 Methods for assessing the toxicity and bioaccumulation of sediment-associated contaminants with freshwater invertebrates, where crustacean Hyalella azteca were exposed to nominal Boron concentrations of 0, 3.13, 6.25, 12.5, 25 and 50 mg/L for 42 days under semi-static conditions. Based on reproduction rate at the end of the treatment period, a NOEC of 6.6 mg Boron/L and a LOEC of 13 mg Boron/L was found which corresponds to a NOEC of 129.4 mg/L and a LOEC of 254.9 mg/L for Sodium triacetoxyborohydride, respectively.
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.
