Additional information

PNEC aqua (freshwater): 67.6 μg/L

PNEC aqua (marine water): 6.76μg/L

PNEC aqua (intermittent release): 676μg/L

PNEC STP: > 30 mg/L

PNEC sediment (freshwater): 345 μg/L

PNEC sediment (marine water): 34.5 μg/L

PNEC soil: 29.3 μg/L

PNEC oral: No bioaccumulation of "3-hydroxy-2-(hydroxymethyl) -2-methylpropionaldehyde" is expected from

the low octanol/water partition coefficient. No relevant secondary poisoning is therefore expected.

Beside this fact: PNECoral = 21 mg/kg food = 21 ppm.
