EC number: 201-545-9
CAS number: 84-61-7
The PNEC for waste-water treatment is 10
mg/l based on the NOEC of 100 mg/l and an assessment factor of 10.
Dicyclohexyl phthalate has been
investigated for acute aquatic toxicity in fish (result LC50 (96h,
Oryzias latipes) > 2 mg/l), in daphnia (result EC50 (48h daphnia magna)
> 2 mg/l) and algae (result EC50 (72h, Pseudokirchnerella subcapitata) >
2 mg/l), the substance is readly biodegradable and has a BCF of 85
therefore it can not be classified for acute aquatic toxicity.
One long-term toxicity to aquatic
invertebrates (Daphnia magna) showed a NOEC (21d)= 0.181 mg/L.
Additionally a NOEC (64d) of 66.6 μg/l was identified in the fish sexual
development study. Some other effects were observed in lower
concentrations but should not be accounted for classification purposes.
Considering the above, a classification of
the substance as an Aquatic Chronic 2 (H411), is proposed.
