Description of key information

For HDI trimer a test with activated sludge with a duration time of 3 hours was performed using a method comparable to OECD 209. A 3h-EC10 = 8800 mg/L as well as a 3h-EC50 = 3828 mg/L  was obtained.

Key value for chemical safety assessment

EC50 for microorganisms:
3 828 mg/L
EC10 or NOEC for microorganisms:
880 mg/L
