Erratum

This article refers to:

Submicron Particle Monitoring of Paving and Related Road Construction Operations

The JOEH apologizes for an error in the May 2012 article, “Submicron Particle Monitoring of Paving and Related Road Construction Operations” by Alice Freund, Norman Zuckerman, Lisa Baum, and Debra Milek. The footnote for Table III reads correctly below.
