Can lead from old water pipes and imported ceramics cause heart disease?
Even low levels of lead from old pipes, imported ceramics, and household dust can damage blood vessels and raise heart disease risk. A 2026 global analysis confirmed lead exposure contributes to cardiovascular deaths at levels below official action thresholds.
Where the lead comes from
Lead gets into your body mainly through old water pipes, imported ceramic dishes, certain spices, and dust from lead paint in older homes. You can't see, taste, or smell it in your water. Even "lead-free" brass fittings can leach small amounts of lead, especially in hot water.
What the research says
A 2026 analysis in Front Public Health using Global Burden of Disease data found that lead exposure causes a large share of cardiovascular deaths worldwide. The damage happens at blood lead levels well below the official "action" threshold most doctors use.
Lead damages blood vessel walls, speeds up plaque buildup, raises blood pressure, and throws off heart rhythm. These effects add up over a lifetime of low-level exposure from everyday sources.
How to lower your exposure
Run cold water for 30 seconds before drinking if your home has old plumbing. Use a certified lead-removing water filter (look for NSF 53 certification). Avoid imported ceramic dishes with bright glazes for food and drinks. If your home was built before 1978, get a lead dust test.
