Description of key information

There is one reliable (Klimisch 1) toxicity to microorganisms study available for the test substance, Dantocol DHE. The study was conducted to OECD 209 test guideline and acording to GLP (SafePharm, 2007). The study was conducted over 3-hours and the 3-hour respiration inhibition NOEC was determined to be 1000 mg/L based on nominal test concentrations. The 3 -hour EC50 was determined to be >1000 mg/L based on nominal test concentrations. This study result demonstrates that the test substance, Dantocol DHE, does not cause significant respiration inhibition in microorganisms, under the conditions of the test.

Key value for chemical safety assessment

EC50 for microorganisms:
1 000 mg/L
EC10 or NOEC for microorganisms:
1 000 mg/L
