WebJul 1, 2024 · In this study, by exploring the correlation of individual PAHs concentrations (CPAHs) in Taihu Lake sediments reported in the past twenty years with their annual emissions (EPAHs) in the lake... 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.

WebNov 14, 2004 · Measured values of Kow for organic chemicals have been found as low as 10-3 and as high as 107, thus encompassing a range of ten orders of magnitude. In terms … WebHigh logKow chemicals partition to the fat tissue preferentially. Fat can almost be a protective barrier in tox: the chemical is localized to the fat and may not interact with other organs or tissues. Many LD50's must be normalized to account for the differential levels of fat in various organisms. 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. highwaymen art show
