Industry consultants cited selective measurements to claim lead was safely excreted

Evidence

A physician consultant to the industry described an “experiment upon men to determine the amount of lead retention from an exhaust containing lead from ‘ethylized gasoline’ and found that, on the average, 85 percent of the lead inhaled was again exhaled… . [T]he amount inhaled and absorbed in the hazard under discussion is evidently far below the ‘threshold’ of toxicity” (Hayhurst, 1925). — Albert Bandura, Moral Disengagement, 1765

Categorization

• QUESTION: What happened to the 15 percent retained? Retrieving the full Hayhurst experiment would show how the retained fraction was disregarded.
• corroborated: 2 independent passages support this claim — Albert Bandura, Moral Disengagement: How People Do Harm…, 1765
