Short-term toxicity to fish

The acute toxicity of the test substance to fish was tested in a 96 hours study according to the EPA OPP 72-1 guideline. The calculated LC50 was 775 µg/L. The NOEC was found to be 607 µg/L.

Long-term toxicity to fish

The long-term toxicity to fish of the read across substance didecyldimethylammonium chloride (CAS 7173 -51 -5) was determined in the OECD guideline 210 and GLP study. The NOEC was determined to be 32 µg/L. .

Short-term toxicity to aquatic invertebrates

The short-term toxicity of the test item to aquatic invertebrates was determined in a EPA OPP 72-2 guideline and GLP study. The LC50 was determined to be 92 µg/L.

Long-term toxicity to aquatic invertebrates

The long term aquatic toxicity to Daphnia magna of the read across substance didecyldimethylammonium chloride (CAS 7173 -51 -5) was determined in this OECD guideline 211 and GLP study. The measured NOEC value was determined to be 0.01 mg/L.

Toxicity to aquatic algae

The toxicity to aquatic algae was tested in a GLP and guideline read-across study with didecyldimethylammonium chloride (CAS 7173 -51 -5). The EC50 (growth rate) was determined to be 0.021 mg/L and NOEC (growth rate) was determined to be 0.011 mg/L (both values are mean measured values).

Toxicity to microorganisms

The toxicity to microorganisms was determined in an OECD guideline study. The EC50 was determined to be 12.2 mg/L and the EC10 was determined to be 3 mg/L.
