WebChemicals with very high logKow values (i.e, >4.5) are of greater concern because they may have the potential to bio-concentrate in living organisms. For pesticides, higher logKow values are better because such pesticides are less likely to leach or occur as surface runoff to contaminate ground water. LogKow is a very important parameter for predicting the distribution of a substance in various environmental compartments (water, soil, air, biota, etc). Substances with high logKow values tend to adsorb more readily to organic matter in soils or sediments because of their low affinity for water (see Kd/Koc). … See more We do not provide consultancy services.
