This document is a compilation of tables for the data extraction and evaluation of
common sources for environmental releases and occupational exposure of the first 10
chemicals. This document may contain sources that were not used for the risk evaluation of
1-Bromopropane. 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.
