How to Calculate Predicted No-Effect Concentration (PNEC)
13/7/2016· According to this source, the PNEC-fresh water of acetone is 10.6mg/L. That means that if the concentration of acetone present in fresh water (pond/lake/river) is below than 10.6mg/L, the acetone will unlikely cause adverse effects to the aquatic environment. This value is not set randomly. There is a systematic and scientific way to derive it.
