Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Data was not available for 3a,4,5,6,7,7a-hexahydro-4,7 -methano-1H-indene, therefore available data has been read across from 3a,4,7,7a-tetrahydro-4,7 -methanonoindene
Experimental results were identified for the three trophic levels (algae, Daphnia and fish) with variable reliability. Key studies and supporting studies are included in this report. A weight of evidence approach has been taken for both the short term toxicity to fish and short term toxicity to algae and cyanobacteria. The following sections detail the robust summaries prepared for these studies in the appropriate sections. The selected key study is also highlighted in the discussion.
The most conservative acute result was for aquatic invertebrates. One report showed a toxicity value between 0.1 and 1 mg/l, however other reports showed toxicity above 1 mg/l. All of the information was considered adequate for assessment but had limitations. In accordance with REACH Guidance to Regulation on classification, labelling and packaging (CLP) of substances and mixtures the geometric mean has been calculated. This result shows a toxicity value of 4.4mg/l. The existing harmonised classification remains unchanged. The aquatic PNEC was derived using the PETROTOX HC5 method.
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.
