Why is the 2.2 µg/day FDA IRL the threshold?
FDA's Interim Reference Level for children is set at 2.2 µg/day to keep blood lead below 3.5 µg/dL — the CDC reference value. It's a public-health action threshold, not a safe level. There is no known safe blood lead level. The IRL is the public-health action threshold.

the lead overlay map

recovered childhood blood-lead data from Reuters, joined to the harms that tend to follow it. pick any layer in the rail. darker is higher. county layers shade roughly 96 to 99% of US counties; state layers shade all 48 contiguous states plus DC. every layer carries its own Source line.

this is an ecological association, county to county, not a claim about any one person. lead is one driver among several, necessary but not sufficient. the cohort layer reads as a national correlation at the birth cohort's modal age, painted on every state so you can see it against the rest. the defensible signal in the historical record is the steep decline after leaded gasoline was removed, not a mid-century rise.

lead is necessary, not sufficient. the same forces that left lead in old paint and old soil also tracked with poverty, housing age, and disinvestment, and those move with the harms too. read this as one strong thread in a knot, shown county by county, not a single cause and not a verdict on any individual.

the leaded generation: the lag is the argument

children cooked by lead (house paint, dominant for births roughly 1910 to 1955, plus leaded gasoline peaking around 1972) became the adults who acted out decades later, each in the calendar year they reached the age that behavior happens. this is an ecological association across birth cohorts, not a claim about any individual.

childhood lead was a high flat plateau through 1976 and then a cliff, so the only defensible claim here is the post-1976 synchronized decline as cleaner cohorts age in (the canonical Nevin / Reyes result), never a mid-century rise. series that do not fit are kept and sequestered with a stated reason, not deleted. that honesty is part of the argument.

panel 1

one cohort, marched through its life by age

the 1971 to 1976 birth cohort (peak childhood lead). each dot is the calendar year that cohort reached the modal age for that outcome. read left to right: school-leaving and young-offender age around 1990, fraud and financial-failure age in the 2000s, midlife now. green = direction matched the lead hypothesis, amber = it did not (kept, not hidden).

panel 2

cohort overlay explorer

outcome (by birth cohort) integrated childhood blood lead of that cohort

panel 3

correlation: CORE (headline) vs SEQUESTERED (kept, reasoned)

CORE: direction predicted in advance, fits the integrated childhood-lead driver SEQUESTERED: held out of the headline, with a stated mechanism

the headline rests on the strong CORE fits, sorted top to bottom by strength: robbery (r=+0.93), fraud-perpetration arrests (+0.92), cigarettes per capita (+0.89), high-school dropout (+0.85), motor-vehicle death rate (+0.82). bar length is the Pearson r between the outcome and the integrated childhood blood lead of the birth cohort that produces it at its modal age.

panel 4

the driver: US childhood blood lead, 1900 to 2023

integrated paint plus gasoline childhood blood-lead profile (Annest 1983 / NHANES II 1976-80 / Pirkle 1994 / CDC NHANES). a high flat plateau near 16 ug/dL from 1930 to 1976, then the steep post-phaseout cliff. because the input is flat then falls, the cohort signal can only speak to the decline.

defensibility. these are ecological (population) associations between an outcome and the integrated childhood blood lead of the birth cohort that produces it at its modal age. association is not proof. lead is treated as a contributing, necessary-not-sufficient factor, not a sole cause. because childhood lead was high and flat before 1976, the defensible claim is the post-phaseout decline, not any mid-century rise. sequestered series are retained with a stated mechanism, never deleted. sources: recovered Reuters lead data; EPA EJScreen; CDC NCHS; FBI UCR and BJS; US Courts; Federal Reserve; NHTSA; NCES; Census; NIAAA; Fraser, Murderland (2025); driver Annest 1983 / NHANES / Pirkle 1994 / CDC.

How to read the glow

Bright green on the painted decoration means lead-bearing pigment. White ceramic stays dark because there is nothing for the reagent to react with.

!

Hot or acidic food on painted china

Citrus, tomato, coffee, and hot dishes leach more lead than cold food. If the dish glows, do not serve hot or acidic food on it.

✓

Cleared

No glow on the painted decoration after 60 seconds under UV. Re-test after replacing the bottle every 12 months.

Spray or drip onto the surface.

Drip bottle for dishes and decorations. Spray bottle for walls, dust, soil samples.

2

Wait 30 seconds.

The carrier evaporates. The reagent stays.

3

Shine the UV light. Read the glow.

Green means lead. The intensity tracks roughly with lead concentration. No glow means below the detection floor.

Lead Risk Validation: map vs. measured blood lead (Michigan)

Michigan: the map versus the blood tests

Our lead-risk map is built only from public housing age and poverty data. It has never seen a blood test. We held it against Michigan's real childhood blood-lead, tract by tract. Here is the prediction next to what was measured.

What we predicted

Risk from housing age + poverty. No blood data used.

higher predicted risk

What was measured

Share of tested children with elevated blood lead.
lower
higher measured blood lead

Hover any neighborhood to compare both numbers. Where the maps share color, the prediction matched reality.

Why this matters

A risk map is only worth trusting if it agrees with where children were actually poisoned. In Michigan it does, at a moderate level. Most of the country has no public blood-lead map at all. A prediction from data every neighborhood already has brings the same warning everywhere.

Sources: Michigan childhood blood-lead surveillance, aggregated by census tract in Zartarian et al., Environmental Science & Technology, 2024 (DOI 10.1021/acs.est.3c07881). Predicted risk: U.S. Census ACS 2022 housing age + poverty, scored by DetectLead.

The map finds the risk. The test confirms it.
