II. Index to Preamble Discussion of Individual Substances
The table below provides an index by preamble section and subsection to a discussion of the record and the health effects evidence for each of the 428 substances for which new or revised limits were considered. The substances in the index are arranged in alphabetical order and include H.S. and CAS numbers as well as the principal toxicological or other basis for the selection or revision of each limit. For some of these substances, OSHA determined that no change to the existing PEL was warranted. Section X presents the entire standard and includes Table Z-1-A, which shows the new and revised limits as well as those OSHA limits that were not changed by this rulemaking.
