- 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.
