Additional information

1-ethylpyrrolidin-2-one is not expected to adsorb to suspended soil matter when released to the terrestrial compartment. From the water surface the substance will not evaporate into the atmosphere. Over time, 1-ethylpyrrolidin-2-one will preferentially distribute into the water (LEVEL I Mackay v3.0, BASF 2016).
