Description of key information

There is no specific test on toxicity to microorganisms. However, toxicity control data from a test on ready biodegradability can be used for the same purpose and as a key value for chemical saftey assessment. Toxicity control data show that Di-2-EHTDG at a concentration of 16.2 mg/l has no inhibitory effect on the respiration of sodium benzoat by sewage sludge inoculum. 

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
16.2 mg/L

Additional information

No data on respiration inhibition of microorganims is available. In addition to the short description of key information, the substance is highly insoluble in water and readily biodegradable. Furthermore, relevant emission to a sewage treatment plant is not expected.
