... 369000 for the neutral species and zero for the ionic species. For the neutral species KOC is assumed to be 0.41·KOW or 151300, thusKP is 151300 × 0.02 L/kg, i.e., 3027 for a soil of 2% organic ... multimedia environment at 25°C. For environmental pH from 4 to 7, there is no significant effect for p-cresol (or for chemicals for which pKa >> pH), very little effect for 2,4-dichlorophenol ... fewer data for KOA than for KOW, its use is increasing and when available, dataare included in this handbook. KOA has been applied to several situations involving partitioning of organic...
