The solubility of Hgo was determined in 34 pure hydrocarbons, hydrocarbon mixtures, crude oils, and water from -65oC to +65oC (where each solvent remained liquid). The solubility of HgCl2 was also quantified, but in a limited subset of the solvents. The solubility of any Hg species in its respective solvent can be very accurately represented by fitting the data to an exponential function of temperature (E1). A similar volume-based exponential (E2) was best-fit to data for the saturation concentration of Hgo in air. By converting the Hgo solubility equations from a mass basis to a volume basis, and then dividing into E2, temperature-dependent unitless “Henry's Law constants” (E3) were also be calculated.
