Update

Our responses to public comments from Tranche 23 and some earlier tranches are now available - see table below.

Summary of amendments made to IMAP assessments

Public comments have been received for IMAP assessment reports published for each tranche. All comments have been considered by NICNAS and, where appropriate, assessment reports have been amended as part of an ongoing process of refinement and improvement of IMAP outputs.

An overview of comments made regarding specific chemicals and NICNAS's response is provided in the following table. The table also provides information on updates made to IMAP assessments subsequent to their publication. Revised reports can be viewed by opening the links on the CAS Registry number or group assessment names below.

NICNAS is considering additional information provided for some chemicals published in previous Tranches (refer to assessment summary tables).

Based on new information, the chemical has been removed from Tier I assessment table and republished as a Tier II assessment with other related chemicals in Tranche 23.

14 Various Indirect precursors of short chain perfluorocarboxylic acids (PFCAs) Tier II human health Editorial and/or factual corrections. Additional data provided. Reference section: New references and data provided by the stakeholder have been incorporated in the report.
14 Various Perfluoroheptanoic acid and its direct precursors Tier II human health General comment

Grouping rationale: the report currently acknowledges that the toxicity of  perfluoroalkyl heptanoic acid (PFHpA) will be intermediate to PFHxA and perfluorooctanoic acid (PFOA) and ‘Based on toxicokinetic data, it is anticipated that long-term effects would occur at higher doses for PFHpA and its salt, compared with PFOA. However, a separate no-observed adverse effect level (NOAEL) cannot be established’.

NICNAS has considered the use of the analogue 7-H-dodecafluoroheptanoic acid (7-H-PFHpA; CAS No 1546-95-8) for assessing the toxicity of PFHpA. Overall, NICNAS has decided that it is not appropriate to include information in the report on the analogue, 7-H-PFHpA.
