Using the World Wide Web for Risk Assessment: A Spinoff Project, Study Guides, Projects, Research of Cultural History of Europe

Capital Community CollegeCultural History of Europe

Information about a project that utilizes the integrated risk information system (iris) on the world wide web to help risk assessors quickly and easily access important data for their jobs. Instructions for accessing the iris system and using it to find slope factors and oral reference doses for various chemicals, as well as examples of risk calculations and memos to supervisors.

Using the World Wide Web to Do Risk Assessment

Most risk assessors do not have all the data at their fingertips that they need to complete their jobs. As you saw in the LTA, the Slope Factor was an important element of the Cancer Risk calculation and the Reference Dose was an important element of the Hazard Quotient calculation. The Environmental Protection Agency provides this data for each potentially toxic chemical. A risk assessor can have a great deal of difficulty finding this data. This data is probably not easily located in his/her office. It is even possible that the needed data is not available at local libraries.

Because of this situation, the EPA has set up a world wide web service called the Integrated Risk Information System (IRIS). By using IRIS, risk assessors can get the information they need quickly and easily.

Activities:

  1. Log on the internet and locate the IRIS system at the following address: www.epa.gov/ngispgm3/iris

There are many hot links at this site to other parts of the EPA system. Use the glossary of risk-assessment related terms to find the meanings of the following terms.

Attributable Risk

Estimated Exposure Dose

Incidence Rate

Organoleptic

Slope Factor

  1. Using the IRIS site listed, double click on the hot link to List of IRIS Substance Files with links to each file. This will bring you to a list of toxic chemicals which are links to files that give you information about the chemical. Use this system to find the Slope Factor and oral Reference Dose (if applicable) for each of the following chemicals:

Acetone

Benzidine

Cyanide, free
