Lead is not just a kid problem.

Lead accumulates in bone over a lifetime. Every cardiovascular disease event, every drop in cognitive performance, every dialysis line in America has a metal-burden component. The good news: most adult lead exposure now is from things you already own and can identify in 30 seconds.

What lead does to an adult body.

Childhood gets the headlines because the brain is wiring. But the lead you absorbed in childhood is still in your bones, and the lead you absorb today gets added to it. Bone is the body's lead reservoir. It releases lead back into circulation during periods of bone remodeling — which means perimenopause, post-menopause, hormone changes, fractures, and old age all liberate a portion of your lifetime lead burden into the bloodstream all over again.

Population-level data is unambiguous. NHANES (the federal blood-lead survey) and longitudinal cohort studies consistently link adult blood lead to cardiovascular mortality, accelerated cognitive decline, hypertension, and reduced kidney function. There is no known safe blood lead level. The CDC reference value is 3.5 µg/dL — most adult Americans test below it but a meaningful share don't.

Where adults pick up most of their lead today.

If you grew up before 1996, the leaded-gasoline era pre-loaded you. The exposure routes that still matter, day to day, are:

• Vintage and inherited dishware. Decorative china, antique Pyrex, the Mexican Talavera bowl from a trip in the 90s, the inherited tea set. The decoration leaches into food.
• Pre-1986 home plumbing. Lead service line, lead solder at copper joints, brass faucet bodies. First-draw morning water is the highest-lead sample.
• Imported turmeric and other spices. Lead chromate is added as a brightener in some imports. Average ppb on tested spices comes back above 500.
• Wellness-aisle supplements. Particularly herbal teas and "organic" multivitamins. Several common brands deliver more than 100% of the daily reference per serving.
• Yard soil and garden vegetables. Pre-1996 leaded-gasoline deposits and weathered exterior paint dripline contamination. Leafy greens and root crops absorb soil lead.
• Hobbies. Stained glass, fishing weights, ammunition reloading, antique restoration, pottery glazing.
• Old jewelry. Costume and inherited brass-alloy pieces. Skin contact is a minor route; mouth contact is the primary issue if a kid is in the house.

A clean weekend audit.

Two hours, a kit, and a notebook will get you 80% of the answer for an adult household.

1. Run your ZIP through the screener. 30 seconds. Tells you state-level lead service line risk and walkthrough for your specific water pipe.
2. Test every painted dish you eat off of regularly. Decoration first. Vintage and inherited pieces are highest priority.
3. Test the kitchen tap and the bathroom tap. Drop on the brass body. Drop on a solder joint under the sink.
4. Test the spice rack. Especially imported turmeric, paprika, and chili powder. Lead chromate is bright.
5. Test the supplements you take daily. Pour a serving onto a clean plate and drop the reagent on it.
6. Take soil samples from the dripline of the house and from any garden bed. The top 2 inches matter most.

If you have grandkids in the house.

The kid is absorbing roughly 5× more lead per bite than you are. Every leaded surface in your house is doing 5× the damage to a 2-year-old grandchild as it does to you. The good news: the house is yours, the test is fast, and the fixes are usually free or cheap. Move the leaded plate to display. Run the cold tap for 30 seconds. Switch the imported turmeric for a single-source domestic brand.

If your grandkids are a regular presence, the broader Baby-Proof journey on this site applies in full. The 0–6 brain-development window is the same window the kid is in whether they're at your house or theirs.

Start with two free tools.

The ZIP screener gives you the regional read. The dose math gives you the unit converter. The test kit gives you a yes/no answer in 30 seconds.

If you have a baby or toddler in the family, the Baby-Proof journey is built specifically for the 0–6 window.
