CDPH Occupational Lead Program recommends health-based Permissible Exposure Limit (PEL) for lead in workplace air

The Cal/OSHA lead standards are based on lead toxicity information that is now over 30 years old. The California Department of Public Health (CDPH) has recently made a recommendation to Cal/OSHA for a new Permissible Exposure Limit (PEL) based on the low level health effects literature and modeling of the relationship between air lead levels and blood lead levels.

Lead still a health concern for California workers – New data report

According to a new report from the California Occupational Blood Lead Registry, thousands of California workers are still being exposed to lead and have elevated blood lead levels. These workers are at risk for serious long-term effects on their health. While employers in many industries provide mandated blood lead level testing for their employees, there is still significant under-testing in industries where lead is a known hazard. Despite this limitation, the data we collect provide valuable information. For example, among those who test, employers in some industries are much more successful than others in protecting their workforce from lead on the job.
