2EHDPP is a “poorly soluble” substance with tendency to stay undissolved when its concentration exceed the water solubility value. Effects observed in the presence of undissolved test material are not indicative of true toxicity but rather indicates physical effects.
The available studies on the short-term fish toxicity of 2EHDPP are listed in the table below:
Flag and Klimish score
96-h LC50: 15 mg/L
Effects only observed at concentrations >solubility
Griffen et al. (1979a)
96-h LC50 = 1.3 mg/L
Effects only observed at concentrations ≥solubility
Sousa et al. (1978a)
96-h LC50: 14 mg/L
Griffen et al. (1979b)
96-h LC-50: 6.7 mg/L
