- General Information
Three different versions of TRIM.ExpoInhalation (also known as APEX) are available: APEX 3.3 for use within TRIM, and two versions of APEX 4 (APEX 4.3 and APEX 4.5), for stand alone use. For information about and documentation on these releases of TRIM.Expo Inhalation / APEX, please see the TRIM.Expo Inhalation / APEX page. For information on new files, models, etc., please click on "Recent Additions" link at top of page left of the "Search" box.
- Installation Instructions
User’s may install and run TRIM.Expo in “stand alone” mode, or within the TRIM MIMS framework. If running TRIM.Expo within the TRIM MIMS framework, the TRIM installation program will install APEX3.3, which is the version currently compatible with TRIM. If running TRIM.Expo in the “stand alone” mode, follow the instructions in the APEX 4 User's Guides for installing APEX 4.3 or APEX 4.5.
To take advantage of the features associated with running TRIM.Expo (as APEX3.3) as a TRIM “project”, use the TRIM installation program to install required components. The TRIM.Risk User’s Guide, Volume I describes how to run TRIM projects. Volume II describes the use of TRIM.Expo with TRIM.Risk. Example TRIM projects using HAPEM are also available.

- Input Files
Please read installation instructions before installing files.
For TRIM.Expo/APEX4 in the “stand alone” mode, the required versions of national files listed below are included in single packages - see APEX 4.3 and 4.4 Input Files under section 5A below.
For TRIM.Expo within the MIMS framework, the following national databases are required (in addition to what is installed via the TRIM Installation Program in Section 2).
A. National Databases. These national databases can be used with any version of APEX for most applications in the U.S. The user also has the option to use alternative databases (e.g., if the user wishes to model a subpopulation). Examples of the other input files, which are prepared by the user, can be found in the Section 5, Example Applications, below. The three databases below should be installed into subdirectories to the APEX directory specified during TRIM installation (see section 2.1, step 5.a. of the Installation Instructions for TRIM).
Consolidated Human Activity Database (CHAD) and other human characteristics data files (4 MB zip file) (activity diaries, metabolic and physiological parameters) for use with APEX 3.3 - 3/1/2005
Population Files (32 MB zip file) (2000 tract-level Census counts, tract locations, employment probabilities by age and tract) - 4/30/2003
Commuting Database (40 MB zip file) (Adult commuting patterns based on the 2000 Census) - 8/29/2005
B. Utility Programs. Posted below are utility programs for users with particular applications (e.g. use of ISCST outputs or need for census block level results).
- ISCAPEX (216 KB zip file) (2/16/2004) is a DOS-based utility that reformats ISCST3 results into the format
required by APEX for air quality
files and creates the districts input file required by APEX (all versions).
- APEX Block File Builder (384 MB zip file) (8/15/2005) is
a DOS-based utility that creates block-level input data files for all versions of APEX for
locations (i.e. counties). The APEX input files created by the utility
for the selected locations are: sector location file (block
FIPS codes; latitude
and longitude of each block centroid); employment file (block
FIPS codes; employment probability by gender and age group for each block); population
files (one file for each gender; block FIPS codes; population by
age bin for each block); and commuting file (each block FIPS
code and cumulative fractions
of population commuting to work blocks). Included in this zip file is a user's
guide for this utility.
- APEX 4.5 input and output files for modeling ozone (85.6 MB zip file) - August 2012
- APEX 4.3 input and output files for jointly modeling ozone and PM exposures (63.7 MB zip file) - 1/12/2009
- TRIM.Expo (1 run) Example Application - The first zip file package in
step 2 below provides instructions for setting up and running an example
application where TRIM.ExpoInhalation
(i.e., APEX3) calculates inhalation exposure estimates for a single chemical,
study area, facility, and source.
- TRIM.Expo (>1 run) Example Application – The second zip file package below provides instructions for setting up and running an example application where TRIM.ExpoInhalation (i.e., APEX3) calculates inhalation exposure estimates for multiple combinations of chemical, study area, facility, and sources.
- TRIM.Expo (1 run) Example Application (217 MB zip file) - 12/13/2005. This zip file contains 27 files.
- TRIM.Expo (>1 run) Example Application (94 MB zip file) - 12/28/2005. This zip file contains 29 files.
Step 1. If TRIM has not been previously installed, install it using the TRIM Installer. Be sure to select "Inhalation Exposure Assessment with TRIM.Expo" when prompted to "Please select the activities you expect to perform with TRIM."
Step 2. Download the ZIP file for the desired example application:
Step 3. Unzip the zip file from previous step into the "input" subdirectory of your APEX directory (e.g., C:\Models\APEX\input). Be sure to maintain the directory structure of the files being unzipped. This is done by default with WinZip's Wizard interface, and is done by checking the "Use folder names" box in the Extract screen of WinZip's Classic interface.
Step 4. Print the “StepsForTRIM…” pdf file (unzipped in Step 3) and follow its steps.
