The chemical half-lives are now correctly saved to the database.
It is now possible to add new Type 2 and 3 chemicals using the "New Chemical"
button.
The name of the environment is now displayed under the chemical name before
printing the results.
Added Chart display of selected results. These can also be printed with the rest of
the results.
Corrected the description of the save-to-file function in the general Help file.
Updated the Help file for the Print function.
Since the Version 2.20 (December 1999) release:
The aerosol deposition velocity parameter is now entered as the dry deposition velocity
and a scavenging ratio rather than as a combined wet and dry velocity.
Updated terminology to be consistent with recent work.
Suspended sediment is now more correctly referred to as suspended particles and "pure air" is now referred to as air vapour.
Molecular mass is now more correctly referred to as molar mass.
An over-sight in the numerical formatting routine was corrected.
Corrected model name in various Help files and in the readme.txt file.
Calculations now print correctly.
All model output, whether viewed on screen, printed, or saved to a file, are identical except that values in the file are not formatted. This allows the user to see the whole number calculated by the model without any rounding effects.
Removed irrelevent D value totals.
Improved error checking.
Incorrect information in the Help files for the Environmental Properties and Emissions
input forms has been removed.
In the display of results, the layout of the chemical parameters was improved.
The aerosol-air partition coefficient is no longer displayed for Type 2 chemicals where it is not applicable.
A label error in display of Intermedia Transport was corrected. "Water to soil" is now "Soil to air".
Concentration (ug/g ) in sediment solids was wrongly displayed as the value for soil pore air.
Overall D values have been added to Results display.
Results are now saved to a comma separated value file making it more generally accessible to a variety of spreadsheet programs.
The units of Fugacity for Type 1 and 3 chemicals were corrected in the save-to-file output.
The save-to-file output was recording the sediment D value for reaction as that of soil. This has been corrected.
A listing of environment properties used were added to the save-to-file output.
A date and time stamp was added to save-to-file.
Layout of the save-to-file output was generally improved.
All input values are italicized in the printed output to facilitate future simulation duplication.
The layout of the printed output of chemical parameters was improved.
The aerosol-air partition coefficient is no longer printed for Type 2 chemicals where it is not applicable.
The aerosol-water partition coefficient is no longer printed for Type 1 where it is unnecessary and illogical.
The "Save Diagram" option was removed. It did not work consistently. The diagram can be captured using the "Print Screen" button on the keyboard, and pasted into a file to be saved. A note was added to the Help file for the Diagram to indicate this.
A date and time stamping option was added to the printed output.
Special thanks to Jenn Brimacombe, Angela McLeod, Chris Warren and the WE512 class of 2001 for checking the model results.
Since the Version 2.10 (September 1999) release:
The values displayed in the Diagram for concentration in soil and sediment have been corrected. Previously there was an error in the unit conversion.
The units listed for Fugacity in the Tables of Printed Results have been corrected.
The typographical error in the "note" about the air and water densities was corrected.
