A new report from the Occupational Health Branch presents data on adults with elevated blood lead levels (BLLs)—now defined by health agencies as 5 micrograms of lead per deciliter (µg/dL) and higher. Between 2012 and 2014:- More than 6,000 workers were identified with an elevated blood lead level.
- The majority were male, aged 20–59, and had a Hispanic surname.
- 60% of workers with BLLs ≥10 µg/dL worked in the manufacturing sector, followed by 14% in construction.
Long-term lead exposure at levels above 5–10 µg/dL increases the risk for health effects such as hypertension, kidney disease, cognitive dysfunction, and adverse reproductive outcomes.
Even higher blood lead levels continue to be a problem among California workers. Blood lead levels of 40 µg/dL and above were reported among workers in industries that handle lead-containing bullets and firearms, and metal-related and construction industries.
