The following problems or errors have been noted for Version 6.00.
The density of aerosols in the "EQC standard environment" is listed as 2400 instead of 2000 kg/m3.
For Type 2 chemicals, when saved to the database, the values are stored incorrectly.
For Type 1 chemicals, in the model output, the units for the Henry's Law Constant are incorrectly displayed as Pa.m3/m. The units should read Pa.m3/mol.
The calculation of the reaction D value for coastal water wrongly uses the volume of freshwater. This will cause the fugacity and concentration for coastal water to be incorrect.
The unit conversion for the Inflow Concentration in Water from ng/L to kg/m3 is incorrectly calculated and should be 1000 times greater than reported in the Results. This value is not used for any subsequent calculation.
To get agreement with EQC (version 2.02) using ChemCAN (version 6.00), in addition to correcting the density of aerosols as noted above, it is necessary to set the aerosol partitioning correlation such that Kp = 5.76×10-13 KOA rather than the standard Kp = 1.5×10-12 KOA in the chemical properties window and make the following changes to the EQC standard environment in ChemCAN (i) set the sediment burial rate to 2×10-7 m/h, (ii) set the diffusion to higher altitudes and leaching from soil rates to 0 m/h. With these changes, agreement is still not complete. In EQC KOC is calculated as 0.41KOW while in ChemCAN it is calculated as 0.411KOW. This slight difference causes all of the partitioning to solids in ChemCAN to be slightly higher than in EQC.
"Fugacity" is mis-spelled on the About screen.
Chemical property values can be changed by the user and are thus entirely the responsibility of the user. Every effort is made to include reasonable values but the included database is NOT to be used as a source. Most values may vary slightly, however, mistakes also occur. For example, the solubility for p,p-DDT in the database is incorrect.
