2. What is ITER?
Free Internet database of human health chronic risk values from organizations around the world for 640+ chemicals.
ITER provides:
Risk value data in a side-by-side table format
The underlying basis and rationale for each risk value
A synopsis that explains differences in risk values
A link to each organization’s website or source document
A forum through which independent parties can share their peer reviewed risk values
A resource to ensure that risk managers do not “miss” useful data

3. Arsenic Search in All TOXNET Databases
10 records containing the
word “arsenic” found in ITER

4. Search Retrieval for Arsenic, including Primary Record

5. Summary Table for Arsenic, Inorganic

8. Why do we need RiskIE? To facilitate information exchange early in the process!
Chemical use has outpaced risk values – need to ensure we do not duplicate effort
Risk assessment values vary across organizations – opportunity for information exchange early in process
Risk Assessments receive intense review – so need to ensure that all sources of useful data have been tapped
