var fDesc=new Array(); fDesc[0] = "ChemCAN is a Level III model of 24 regions of Canada. It estimates average concentrations in air, fresh surface water, fish, sediments, soils, vegetation, and marine near-shore waters. It is intended to assist in human exposure assessment. Designed for use in Canada, a database of 24 regions of Canada is included. Other regions can be defined by the user and added to the database, however, areas should have a radius of at least 300 km. For investigations involving smaller areas, air dispersion will dominate and a plume model may be more appropriate.

Features of ChemCAN:

- Provides a database of chemicals and chemical properties.
- Permits temporary additions/changes of chemicals and their properties to a simulation.
- Permits permanent additions, changes, and deletions of chemicals and their properties to the database.
- Provides a database of environments and environmental properties.
- Permits temporary additions/changes of environments and their properties to a simulation.
- Permits permanent additions, changes, and deletions of environments and their properties to the database.
- Provides context-sensitive Help.
- Displays and prints the ChemCAN model calculations, as performed by the program.
- Allows the printing of simulation tables and the summary diagram.
- Allows the program results to be saved as a spreadsheet file."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
