Key value for chemical safety assessment

EC10, LC10 or NOEC for microorganisms:
4 mg/L

Additional information

The assessment of toxicity to microorganisms is based on data obtained for the similar substance adamantyltrimethylammoniumsulfate (CAS 1000777-61-5), in a test conducted with activated sludge, following the guideline EN IS0 9509: 2006 (DEV L38). An EC20 value of 44 mg/L, based on nitrification rate, was derived for 4 hours exposure while the EC10 is 4 mg/L(BASF AG, 2008). this value will be used for further assessment.
