Short-term toxicity to fish

The 96 hour LC50 value of 3a,4,5,6,7,7a-hexahydro-4,7-methanoinden-6-yl acetate in fish (Carassius auratus) was estimated to be 18.04851 mg/L (ppm) .This value suggests that the test substance will exhibit short term toxicity to fish under Chronic Category 3.

Long-term toxicity to fish

The 14 days long term toxicity to fish (LC50) as estimated by the ECOSAR model was 346.663 mg/L. This value suggests that 3a,4,5,6,7,7a-hexahydro-4,7-methanoinden-6-yl acetate does not represent long term toxicity to fish.

Short-term toxicity to aquatic invertebrates

The 48 hour EC50 value of 3a,4,5,6,7,7a-hexahydro-4,7-methanoinden-6-yl acetate in daphnia was estimated to be 53.80956 mg/L (ppm) . This value suggests that the test substance will exhibit short term toxicity to aquatic invertebrate under Chronic Category 3.

Long-term toxicity to aquatic invertebrates

According to annex IX of column I;Long-term toxicity testing on invertebrate (species : Daphnia) need not to be conducted as it is already provided as a part of Annex VII requirements.

Toxicity to aquatic algae and cyanobacteria

The 72 hour EC50 value of 3a,4,5,6,7,7a-hexahydro-4,7-methanoinden-6-yl acetate in green algae (Pseudokirchnerella subcapitata) was estimated to be 13.07479 mg/L (ppm) .This value suggests that the test substance will exhibit toxicity to aquatic algae under Chronic Category 3.

Toxicity to microorganisms

The IGC50 value of biphenyl-2,2'-diol in Tetrahymena pyriformis for 48 hrs was found to be 24.5 mg/L (ppm) .This value suggests that the test substance will exhibit toxicity to microorganisms under Chronic Category 3.
