Lead in the Workplace –  The New Science

A one-day scientific symposium moderated by John Howard, MD, Director of NIOSH

The CDPH Occupational Lead Poisoning Prevention Program (OLPPP) has reviewed available scientific information and made health-based recommendations to Cal/OSHA for revising its General Industry Lead Standard and Lead in Construction Standard. These standards aim to protect workers exposed to lead on the job. This symposium, held on November 13, 2013, explored the scientific basis for the CDPH recommendations.

Scientific experts provided detailed presentations on the current literature on health effects of low-level lead exposure and the newly released Cal EPA report on modeling of the air lead/blood lead relationship. A CDPH representative presented the basis for the CDPH’s recent Permissible Exposure Limit (PEL) recommendation to Cal OSHA. In addition, a panel of experts from related disciplines responded to the presentations and participated in a question-and-answer session with symposium attendees.
