Effect conc.:
0.277 mg/L
Nominal / measured:

Conc. based on:
test mat.
Basis for effect:
other: (Q)SAR prediction
Remarks on result:
other: Chemical may not be soluble enough to measure this predicted effect.
Duration:

Effect conc.:
0.142 mg/L
Nominal / measured:
nominal
Conc. based on:
test mat.
Basis for effect:
other: (Q)SAR prediction
Remarks on result:
other: Chemical may not be soluble enough to measure this predicted effect.
Details on results:
A 96 h LC50 value of 0.277 mg/L has been calculated for the effects of the test substance on the mortality of the Algae group.
A NOEC value of 0.142 mg/L has been calculated for the effects of the test substance on the mortality of the Algae group.
This result signifies that the test substance is not expected to be toxic at the limit of solubility. This result is above the LoS (limit of solubility), therefore the substance is non-toxic at the limit of LoS and NOEC is >LoS.
The model indicated that Stoddard solvent possess properties indicating a potential hazard for the environment (acute toxicity for fish, invertebrates, and algae (in the range of 0.1 – 1.0 mg/l) based on nominal loadings.
