Administrative data

Description of key information

No aquatic toxicity testing was conducted on the RM of W2C + WC. Instead aquatic toxicity data from two read across source substances, tungsten carbide and sodium tungstate was used.

Additional information

Due to similar water solubility and toxicity for the target substance compared to the source substance, the resulting read across from the source substance to the target substance is appropriate. In addition, read across is appropriate because the classification and labelling is similar for the source substance than the target substance, the PBT/vPvB profile is the same, and the dose descriptors are, or are expected to be, similar for the source substance. For more details, refer to the read-across category approach included in the Category section of this IUCLID submission and/or as an Annex in the CSR.
