Description of key information
Fatty acids, C8-10, zinc salts:
Toxicity studies of fatty acids, C8-10, zinc salts are not available. In the assessment of environmental toxicity of fatty acids, C8-10, zinc salts, read-across to the assessment entities zinc and C8 -10 fatty acids is applied since zinc cations and fatty acid anions determine its fate and toxicity in the environment. Please refer to the respective assessment entity for further details.
C8-10 fatty acids:
The lowest acute EC50 for freshwater invertebrates, 63 mg/L, was observed for the effect of octanoic acid (C8) in a reliable, GLP-conform 48 h toxicity test with Daphnia magna conducted similar to OECD 202.
Zinc:
Key data (lowest EC50 values) are:
-for Ceriodaphnia dubia: 0.413 mg Zn/l (single value) at low pH and low hardness
-for Ceriodaphnia dubia: >0.53 mg Zn/l (single value) at low pH and high hardness
-for Ceriodaphnia dubia: 0.147 mg Zn/l (geomean value) at neutral/high pH and low hardness
-for Ceriodaphnia dubia: 0.228 mg Zn/l (geomean value) at neutral/high pH and high hardness
Key value for chemical safety assessment
