Water solubility (as water-accommodated fraction) of Wash Oil at 20 °C

in test medium (daphnia) at various loadings:

Based on measured data (see tables below), the oil-related TOC values were approximately

  • 4.0 mg/L (at 10 mg oil/L),
  • 8.0 mg/L (at 50 mg oil/L),
  • 16.5 mg/L (at 100 mg oil/L),
  • 32 mg/L (at 250 mg oil/L),
  • 85 mg/L (at 1000 mg oil/L)
