Description of key information

The 96 hr LC50 is 15.7 mg/l

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) tested the toxicity of dicyclopentadiene to four species of fish. The range of LC50 values reported within the paper was between 15.7 -31.1mg/l. The study followed a method similar to standard guidelines but did not include analytical confirmation of the exposure concentrations.

The OECD SIDS identified an Environmental Agency Japan test which showed the 96hr LC50 to be 4.3 mg/l. (MITI 1995) This study was unavailable for review but is included here as part of a weight of evidence approach together with the Bentley studies.
