Description of key information

There are no experimental data on aquatic toxicity available for the test item. Therefore, a read-across approach is applied.

Additional information

Short term toxicity to fish

There are no experimental data available for the test item. Therefore, a read-across approach is applied. The following LC50 values after 96 h of epxosure were obtained in fish for the respective source substance:

LC50 = 5.7 mg LAS TEA/L

LC50 = 1.67 mg LAS Na/L

LC50 = 460 mg DEA/L

Long term toxicity to fish

There is no experimental data available for the test item. Alternatively, a read-across approach is applied. As lowest threshold value the following value was obtained in fish for the source substance:

NOEC = 0.23 mg LAS Na/L

Short term toxicity to aquatic invertebrates

There are no experimental data available for the test item. Therefore, a read-across approach is applied. The following EC50 values were obtained for short-term toxicity to daphnia for the respective source substance:

EC50 = 18.8 mg LAS TEA/L

EC50 = 2.4 mg LAS Na/L

EC50 = 30.1 mg DEA/L

Long term toxicity to aquatic invertebrates

There is no experimental data available for the test item. Alternatively, a read-across approach is applied. The following values were obtained for the respective source substance:

NOEC = 0.5 mg LAS Na/L

EC10 = 1.18 mg LAS/L

NOEC = 2.9 mg C12LAS/L

Toxicity to aquatic algae

There are no experimental data available for the test item. Therefore, a read-across approach is applied. The following ErC50 values were obtained for toxicity to aquatic algae for the respective source substance:

ErC50 > 56.2 mg LAS TEA/L

EC10 = 17.3 mg LAS TEA/L

NOEC = 3.4 mg LAS TEA/L

ErC50 = 128 mg LAS Na/L (Scholz RL1)

EC10 = not determined

NOEC = 2.4 mg LAS Na/L (Scholz RL1)

ErC50 = 14.9 mg DEA/L

EC10 = 2.4 mg DEA/L

NOEC = not determined

Toxicity to microorganisms

There are no experimental data available on the test item. Therefore, a read-across approach is applied. An EC10 of 55 mg/L was determined for source substance 1 (LAS TEA). Source substance 3 (DEA) did not induce any effects to aquatic microorganisms under the conditions of the test up to a concentration of 1000 mg/L.
