Final Risk Evaluation for
1,4-Dioxane

Systematic Review Supplemental File:

Data Quality Evaluation of Environmental Hazard Studies

CASRN: 123-91-1

December 2020


-------
This document is a compilation of tables for the data extraction and evaluation for 1,4-Dioxane.
Each table shows the data point or set or information element that was extracted and evaluated
from a data source in accordance with Appendix D of the Application of Systematic Review in
TSCA Risk Evaluations. If the source contains more than one data set or information element, the
review provides an overall confidence score for each data set or information element that is
found in the source. Therefore, it is possible that a source may have more than one overall
quality/confidence score.
