Description of key information

The 72-h ErC50 of 340 mg/l and the 72-h NOEC of 36 mg/l in Pseudokirchneriella subcapitata are used in the assessment.

Key value for chemical safety assessment

EC50 for freshwater algae:
340 mg/L
EC10 or NOEC for freshwater algae:
36 mg/L

Additional information

One study is available for the growth inhibition of TAEE in algae, which is a GLP-compliant OECD 201 study with Pseudokirchneriella subcapitata (Harlan Laboratories Ltd, 2009g). The concentrations were analytically verified, the 72-h ErC50 is 340 mg/l and 72-h NOEC for growth rate of 36 mg/l based on measured concentrations.

Additionally, a GLP-compliant EU Method C.3 study is available with Pseudokirchneriella subcapitata for the structurally related aliphatic ether TAME (SafePharm Laboratories, 2003b). The concentrations were analytically verified, the 72-h ErC50 is 780 mg/l and 72-h NOEC for growth rate of 77 mg/l based on measured concentrations.

The 72-h ErC50 of 340 mg/l and 72-h NOEC for growth rate of 36 mg/l are used in the assessment.
