Occupational Lead poisoning prevention program

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. This symposium, held on November 13, 2013, discussed 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 Cal/EPA report on modeling of the air lead/blood lead relationship. A CDPH representative presented the basis for the CDPH's Permissible Exposure Limit (PEL) recommendation (PDF) to Cal/OSHA. In addition, a panel of experts from related disciplines responded to the presentations and participated in a Q & A session with symposium attendees.
