>>I have inserted total Hydrocarbons emission factors in my area, but the results don't show this pollutant. I am sending you a print screen. Any idea why this is happening?
Hi Pedro.
That menu option you are using just gives quick access to the most common pollutants. After you have select a pollutant on that menu (e.g. carbon monoxide), you you will then see another button at the top of the resulting results screen where you can select among all of the pollutants.
If you don't see the full range of pollutants listed from this buttons drop down menu, then you may need to go back to the General: Basic Parameters screen and make sure that you have included "complex effects" in the Scope and scale settings.
See screenshots..
I hope this helps,
Charlie
