A large cohort study of 58,000 lead-exposed male workers in the US has found strong positive associations between high blood lead levels and mortality from lung cancer, pancreatic cancer, heart disease, and chronic renal disease, as well as increased lung and liver cancer incidence. Researchers used the highest recorded blood lead as the exposure metric and reported lung cancer rate ratios of 2.0–2.5, which they argue are unlikely to be explained by smoking differences based on a subset analysis. This work provides robust epidemiological evidence reinforcing the carcinogenicity of inorganic lead, a finding directly relevant to occupational and environmental health risk assessment and public health policy.
