What Lead Does to 1,000 People

Every dot is a person. Every colored dot carries a lead-linked condition. Drag the slider to change the blood lead level. Watch the crowd change. This is not a model — this is the peer-reviewed literature, translated into faces.

Each dot = 258,000 Americans · Total represented: 258 million adults
Blood lead level 3.5 µg/dL

The same people. Multiple conditions.

Lead doesn't pick one thing to damage. It disrupts prefrontal cortex development, mitochondrial function, renal proximal tubule cells, vascular endothelium, and hypothalamic-pituitary-adrenal axis regulation — simultaneously. The dots with multiple colors aren't unlucky. They're the rule, not the exception. Comorbidity is the lead signature.

The 1976 peak — 15.5 µg/dL average for US children — wasn't an accident or an edge case. It was the median American child during the era of leaded gasoline, leaded paint, and leaded solder in food cans. The full effect of that exposure is still playing out in the health outcomes of people who are now 50–65 years old.

You can test the source.

The largest remaining controllable exposure for most families is lead-painted dishware used daily. Pre-1992 pottery, china, and ceramics legally contained lead in the decoration pigments. One positive test is enough to break the daily exposure chain.

Stop the daily exposure. Test your dishes.

FluoroSpec identifies lead pigment in 30 seconds. One kit tests dozens of pieces. The population-level damage above came from chronic daily exposure — mostly at the table.
