What Are the Most Important Sources for Updating the
Database?
Figure 17. ACGIH and IARC are the two major
sources for updating.
The main sources for updating existing chemicals are ACGIH
and IARC. ACGIH
publishes every year Documentation of the Threshold Limit Values, Supplement
to the 7th Edition, and changes in these documents are added to the
database. See this page for the
2014 changes. IARC published several important monographs in 2012 that were
added. See the bottom of this page
for details.
