Short-term toxicity to fish
Administrative data

Description of key information
There is no information concerning short term toxicity to fish of n-Decyl methacrylate available.
The results of the aquatic short term toxicity to fish studies on the structurally closely related Isodecyl methacrylate (i-C10-Ester) are considered as representative for the aquatic toxicity of n-Decyl methacrylate (C10 -Ester).
In a study according to guideline DIN 38412 L 18, the 48 hr LC50 for Leuciscus idus is 470 mg/L. No mortalities are observed at 450 mg/l.
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 470 mg/L
Additional information
There is no information concerning short term toxicity to fish of n-Decyl methacrylate available. The results of the aquatic short term toxicity to fish studies on the structurally closely related Isodecyl methacrylate (i-C10-Ester) are considered as representative for the aquatic toxicity of n-Decyl methacrylate (C10 -Ester).
LC50 [48 h]: 470 mg / L This is supported by an LC0 of >10000 mg/L for Isotridecyl.
In a study according to guideline DIN 38412 L 18, the 48 hr LC50 for Leuciscus idus is 470 mg/L.
No mortalities are observed at 450 mg/l. The water solubility of Isodecyl methacrylate is in the range of 200 µg/L .Therefore, it appears that saturated solutions of the substance are non-toxic to fish. This is confirmed by the results of fish toxicity testing with the structural analogue isotridecyl methacrylate.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
