Since the first edition in 1948, Patty’s Industrial Hygiene and Toxicology has become a flagship publication for Wiley. During its nearly seven decades in print, it has become a standard reference for the fields of occupational health and toxicology. The volumes on industrial hygiene are cornerstone reference works for not only industrial hygienists but also chemists, engineers, toxicologists, lawyers, and occupational safety personnel.

Volume 3 covers Recognition and Evaluation of Physical Agents and Biohazards. All of the chapters have been updated and a new chapter on Robotics has been added. These subjects are increasing in importance to industrial hygienists.
