Description of key information

One long term toxicity to fish study was available.  No effect concentration of 0.98±0.25 mg/l  was reported in the study.  

Key value for chemical safety assessment

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

Bentley et al (1976) report the results of a long term toxicity study with dicyclopentadiene. At the highest test concentration in the study no mortality or change in behaviour was observed. Although this study is not GLP and does not fully comply with standard guidelines, it is considered to be adequate for the assessment of this endpoint.
