EPA-Expo-Box: A Novel Innovation for Risk Assessors

As a college student, I always found Wikipedia to be one of the simplest, yet most innovative resources created in the last decade. Wikipedia’s ability to compile and aggregate different information in a single spot on the internet makes it a unique web resource to accomplish any number of tasks across a wide variety of disciplines and settings.

Now—post graduation and working as a student contractor in EPA’s Office of Research and Development—I’ve found out that EPA scientists have developed their own innovative, encyclopedia-like resource for exposure assessment information. Links to databases, models, guidance documents and other resources are organized by topics such as exposure assessment approaches, chemical classes, environmental media, routes of exposure, life stages and populations, and more.

This new website, EPA-Expo-Box (short for EPA Exposure Toolbox), has compiled links to more than 800 exposure assessment tools all in one user-friendly format.

For example, imagine a scientist examining an outdoor air or water pollutant. This scientist could use EPA-Expo-Box’s Media Tool Set to help identify information needed to assess how this pollutant may be interacting with the environment, and tools needed to estimate exposures among the people who may come into contact with the air or water. This scientist could access resources on potential sources, fate and transport, or measured concentrations of the chemical in the air or water. With 800+ resources readily in hand, risk assessors can make informed scientific decisions to better protect the public and the environment from harm.

Prior to EPA-Expo-Box, there were no comprehensive publicly available resource for exposure assessment tools and information.  Recognizing this need, EPA scientists set out to design an online “one stop shop” for   resources that an exposure assessor may need. This free resource fills a specific niche in the risk assessment community. As an interactive scientific resource, it contains links to databases, models, guidance documents, and reference materials, along with step-by-step assistance for conducting exposure assessments to help guide users through the exposure assessment process.

Because it is completely online, users can access all of the tool sets at the touch of a button on their laptop, tablet, or smartphone. This versatility gives EPA scientists and others access to exposure assessment information regardless if they are in the field or in a laboratory. Like any good resource, EPA-Expo-Box is simply a handy tool to have when you need it most.

The other advantage of an online-only platform?  When new resources become available, updates can be made quickly and easily. No longer will users have to wait for the next edition or version to get the most up to date information. The dynamic nature of EPA-Expo-Box is increasingly crucial in the ever changing field of risk and exposure assessment.

Day in and day out, it is versatile and dynamic innovations like EPA-Expo-Box that better help EPA and others access information they need to more effectively evaluate potential risks to human health and the environment in the communities in which we all live and work.

    Another tool for anyone working on the biomonitoring is the Association of Public Health Laboratories’ Biomonitoring Toolkit.

    Document libraries include overarching guidance documents, laboratory methods, communication templates, and stories from the field. Links point to other relevant resources. A Discussion Board, which functions similar to a listserv, facilitates conversation among subscribers.

    To access the Toolkit, one needs to sign up for an account:
    • Visit and click on ‘Create an Account’ (upper right).
    • Email to let us know which email address you used and we’ll add that to the Toolkit.
    • Once added, turn on your ‘alerts’ for the site (an email message to notify you when another user has posted a new topic or engaged in a discussion, similar to a listserv). Just follow the instructions in the User Guide found in the upper left corner of the page. For questions, please contact
