This document is a compilation of tables for the data extraction and evaluation for C.I. Pigment Violet
29 (CASRN 81-33-4). 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 (U.S. EPA. 20.1.8). 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.

in water; however,
no details were

to a well-

substance under

8. Consistency
of Exposure

Reviewer cannot

12. Exposure
route and
method

Unacceptable

The study aimed at
investigating
animal toxicity to
an atmosphere
saturated with
vapors of the
volatile
component of
PV29. Since the
study said that
dust is expected by
inhalation, this is
an inappropriate
exposure method.
Further, specific

missing such as
the equipment and
method used to
generate the
chamber
atmosphere,
description of the
inhalation
chamber, failure to
use an analytical
method to analyze
the test
atmosphere

Also, the authors
admitted the
limitations of the

that "the inhalation

insufficient for
non-volatile
