Description of key information
Additional information
Toxicity to fish :
Short term toxicity to fish, Oryzias latipes based on the mortality observed by 4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-one for 96 hrs. was estimated at dose level of 2.571 mg/L (LC50). Thus,according to the CLP criteria (considering the LC50 value)4-(2,6,6-trimethylcyclohex -1-ene-1-yl)-but-3-ene-2-one will exhibit short term toxicity to fish in chronic 2 classification category.
Toxicity to invertebrate :
Short term toxicity to invertebrate Daphnia magna by 4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-one for 48hrs. was estimated as EC50 equal to 1.6413 mg/L.Thus,according CLP criteria, 4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-one is likely to exhibit short term toxicity to invertebrate Daphnia magna in aquatic chronic 2 classification category.
Toxicity to algae :
The no observed effect level (NOEC) value of 4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-one in algae (Pseudokirchnerella subcapitata) in a 72 hr study on growth effect was estimated to be 0.656195 mg/L.Thus considering the NOEC value it is concluded that 4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-one could not be considered as toxic to aquatic algae.
