Lead hides in more household items than most people realize. Paint, plumbing, ceramics, imported spices, vintage furniture, and even yard soil can all be sources. Some of these are well known, others are surprisingly common, and many remain in homes long after the regulations that banned them. Here’s a practical breakdown of where lead shows up and what to watch for.
Paint in Pre-1978 Homes
Lead-based paint is the most widespread source of lead in American households. It was banned for residential use in 1978, but it remains on walls, trim, doors, and window frames in millions of older homes. When the paint is intact and in good condition, it poses little immediate risk. The danger comes when it deteriorates: chipping, peeling, or cracking into a pattern sometimes called “alligator skin.” That breakdown releases lead-laden dust and paint chips, which settle on floors, windowsills, and hands.
Renovation is another major trigger. Sanding, scraping, or demolishing painted surfaces in a pre-1978 home can pulverize lead paint into fine dust that spreads through the house. Research in Environmental Health Perspectives found that pulverized lead paint dust, combined with contaminated soil tracked indoors, is actually a more significant pathway of exposure for children than intact paint on walls. If you live in or are renovating an older home, this is the single biggest item to address.
Plumbing, Pipes, and Faucets
Congress banned lead solder and lead pipes in drinking water systems in June 1986, but homes built before that date may still have lead solder connecting copper pipes, lead service lines running from the street to the house, or older brass fixtures that contain lead. Even some fixtures installed after the ban contained small percentages of lead until stricter “lead free” definitions took effect in 2014.
Lead leaches into water primarily when it sits in contact with these materials for hours, which is why the first draw of water in the morning tends to have higher concentrations. The EPA now requires public water systems to inventory their service lines and replace lead ones, but progress varies by city. If your home was built before the late 1980s, running cold water for 30 seconds to two minutes before drinking or cooking can reduce exposure. Hot water pulls more lead from pipes, so always start with cold for anything you’ll consume.
Ceramics, Pottery, and Glazed Cookware
Leaded glazes have been used on ceramics for centuries because they produce a smooth, colorful, glossy finish. The concern today is mainly with handmade or imported pottery, particularly pieces from Mexico, China, and parts of Europe. A case study published in the Canadian Medical Association Journal documented cookware whose glaze was 17% lead by weight, even though the ceramic body itself contained none. Acidic foods like tomato sauce, citrus, or vinegar accelerate leaching from these glazes.
Items to be cautious about include brightly glazed bean pots, tagines, decorative plates used for serving food, and hand-painted mugs purchased abroad or at craft markets. Mass-produced dinnerware sold by major U.S. retailers is generally tested and compliant, but older sets, inherited china, and pieces with visible crazing (tiny cracks in the glaze) deserve more scrutiny.
Imported Spices and Traditional Cosmetics
Some of the most concentrated lead sources found in homes are products that fly under the radar entirely. Oregon health officials have documented staggering lead levels in traditional cosmetics and certain imported spices. Sindoor, kumkum, and tikka powders, used in Hindu religious and cultural practices, have been found with lead concentrations tens of thousands of times above recommended limits. One brand of sindoor tested at 43% lead by weight.
Kohl (also called kajal, surma, or sormeh), a black eye cosmetic used across South Asian and Middle Eastern cultures, is another major source. Samples purchased both locally and abroad have tested at up to 59% lead. Between 2018 and 2019, Oregon health departments identified 25 lead poisoning cases traced to kohl or surma alone.
Turmeric is a less obvious risk. The concern centers on small batches hand-carried into the U.S. from India or Bangladesh rather than products sold in major supermarkets. One sample brought from India contained 1,240 parts per million of lead. In some regions, lead compounds have historically been added to turmeric to enhance its yellow color and weight. Seven lead poisoning cases in Oregon were linked to this source during the same period.
Children’s Toys, Jewelry, and Accessories
U.S. law now limits lead in accessible parts of children’s products to no more than 100 parts per million. That standard, enforced by the Consumer Product Safety Commission, covers toys, clothing fasteners, and children’s metal jewelry sold domestically. But products purchased abroad, ordered from unregulated online sellers, or found at thrift stores and flea markets may not meet these limits. Inexpensive metal charms, toy jewelry, and painted figurines are the most common offenders. Young children who mouth these items face the highest risk.
Vintage Furniture and Antique Items
Flea market finds, estate sale furniture, and architectural salvage pieces are popular in home décor, but anything painted before 1978 should be assumed to contain lead until tested. The Minnesota Department of Health flags several categories of vintage items as likely lead sources: painted cribs, wicker chairs, wooden stools, decorative tin panels, metal boxes, old screen doors, and salvaged building components like window sashes, balusters, and door hardware. Cracked, chipped, or flaking paint on any of these items releases lead dust into your living space.
Less obvious items include lead crystal glassware (which can leach lead into beverages stored in it), old typeset letters made from lead alloy, and vintage costume jewelry. If you’re using painted vintage pieces in a home with young children, testing is especially important.
Soil and Household Dust
The ground around your home can be a hidden lead reservoir. Decades of leaded gasoline emissions deposited lead into soil nationwide, particularly along busy roads and near older buildings where exterior lead paint has weathered and flaked off. That contaminated soil gets tracked indoors on shoes and paws, becoming household dust.
Research has shown that soil lead and house dust, not intact paint on walls, are the pathways most strongly associated with elevated blood lead levels in children. Kids playing on the floor, putting hands in their mouths, and spending time in yards with bare soil near foundations are at the greatest risk. Keeping floors damp-mopped, removing shoes at the door, and covering bare soil with mulch or grass are simple ways to reduce this route of exposure.
How to Test Items in Your Home
The EPA recognizes three consumer lead test kits for use on common household surfaces. The most widely available is the LeadCheck swab kit, which works on wood, drywall, plaster, and metal. You press the swab against the surface, and it changes color if lead is present. These kits are reliable for confirming a positive result, but a negative result on some surfaces (particularly metal or surfaces with many paint layers) is less definitive.
For more certainty, professional testing with an XRF analyzer can measure lead content through multiple layers of paint without damaging the surface. This is worth considering before major renovations in older homes. For water, many local utilities offer free or low-cost testing, or you can order a certified lab kit online. The CDC currently flags any blood lead level at or above 3.5 micrograms per deciliter in children as higher than normal, down from 5.0 before 2021, reflecting the understanding that no level of lead exposure is truly safe.
