Description of key information

Short-term toxicity to fish

The acute toxicity of the structural analogue Blue Sema to Danio rerio was determined in a 96-hour semi-static test according to EU Method C.1 and OECD Guideline 203.The 96 -h NOEC was determined

to be 0.32 mg/L (equivalent to 100 mg/L nominal concentration) and the LOEC > 0.32 mg/L (equivalent to > 100 mg/L nominal concentration).

Short-term toxicity to aquatic invertebrates

In a 48-hour semi-static test according to OECD Guideline 202 the 48-hour EC50 of the test item was determined to be > 0.158 mg/L (geometric mean measured, corresponding to a nominal loading rate of 100 mg/L). The test item had no toxic effect to Daphnia magna up to and including aquatic saturation of the test item.

Toxicity to aquatic algae and cyanobacteria

In the 72 -hour growth inhibition study on algae (Raphidocelis subcapitata) with the read across substance Blue Sema (CAS 1040873 -93 -5) and performed according to OECD Guideline 201 the test item had not any significant toxic effects on the test system. The 72 -h NOEC was determined to be 0.1 mg/L (Limit of detection, nominal 100 mg/L). The 72-h LOEC was determined to be > 0.1 mg/L (Limit of detection, nominal > 100 mg/L).

Toxicity to microorganisms

In the study according to OECD 209 with the read across substance Blue Sema (CAS 1040873-93-5) no influence on the specific respiration rates up to 1000 mg/L were shown. The 3-h EC50 and NOEC was determined to be > 1000 mg/L and 1000 mg/L, respectively.
