Chrysene in soil
WebIn certain references, soil-water partition coefficients (e.g., K d or K p) were reported along with the organic carbon content of the soil. In these cases, K oc was computed by dividing K d by the fractional soil organic carbon content (f oc, g/g). If the partition coefficient was normalized to soil organic matter (i.e., K om), it was ... WebThey can also be found in substances such as crude oil, coal, coal tar pitch, creosote, and roofing tar.
