Description of key information
acutely toxic to aquatic algae
Key value for chemical safety assessment
- EC10 or NOEC for freshwater algae:
- 0.424 mg/L
Additional information
There is one reliable study available regarding the toxic effect of 2-ethyhexylchloride to algae. The study was performed according to OECD 201 under GLP conditions with modifications regarding the volatility of the test item (closed vessel, test medium). The test species was Pseudokirchneriella subcapitata. The test concentrations were analytically verified. The 72 -h effect values are as follows based on measured concentrations (geometric mean): ErC10 = 0.424 mg/L, ErC50 > 1.14 mg/L (BASF SE, 2012; report no. 60E0397/11E106).
In conclusion, the substance is acutely toxic to algae.
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.
