Description of key information

The inhibition of the degradation activity of activated sludge is not anticipated when 2-EHA is introduced in appropriate low concentrations.

Key value for chemical safety assessment

EC50 for microorganisms:
112.1 mg/L
EC10 or NOEC for microorganisms:
71.7 mg/L

Additional information

As key study concerning acute toxicity to microorganisms a test performed by BASF SE (1988) according to German Industrial Standard DIN 38412 part 8 was identified, using Pseudomonas putida as test organism. In the static test an EC10 of 71.7 mg/L and an EC50 of 112.1 mg/L after 17 hours of exposure were estimated..
