Why have you derived the Koc for elemental mercury when it is an inorganic compound?
Elemental mercury has had to be treated as an organic chemical for the purpose of deriving Soil Guideline Values (SGV) using the CLEA software. This is because the Johnson and Ettinger model (which models vapour intrusion into the building) was developed for organic chemicals. With the exception of organo-metallic compounds, the vapour pathway is rarely, if ever, needed in the assessment of risks from soil contamination with non-organic substances under ambient conditions; elemental mercury has been the exception. When developing the SGV, we undertook an extensive literature review looking for reported soil-water partition coefficient (Kd) and organic carbon-water coefficient (Koc) values for elemental mercury, with little success. Unfortunately, many of the property estimation methods available are suitable only for hydrocarbons. The source and derivation of the chemical properties used in the derivation of the SGV for elemental mercury , including the Koc, are described our Science r
