Description of key information

Additional information

Reliable short-term toxicity data for freshwater organisms are available for three trophic levels: aquatic invertebrates, fish and algae:

EC50 (48 h) daphnia magna: 1.41 mg/L (EC C.2/ OECD 202, GLP); NOEC: 0.625 mg/L

LC50 (96h) fish: 8.94 mg/L (EC C.1/ OECD 203, GLP); NOEC: 2.5 mg/L

EC50 (72h) algae: 4.15 mg/L (EC C.3/OECD 201, GLP); NOEC: 2.0 mg/L

The lowest acute effect value within the three trophic levels was a 48-h EC50 of 1.41 mg/L observed for the effect of SymWhite 377 on the mobility of Daphnia magna. Long-term toxicity data are not available.

Results on toxicity to microorganisms:

EC50 (respiratory inhibition): 33 mg/L (EC C.11/ OECD 209, GLP); NOEC: 2.4 mg/L
