Lead is a heavy metal that is common in our everyday environment. Historically it has been used in paints, pipes (including connectors/fittings), and gasoline among other places. Today, most industrial uses are limited to lead-acid batteries, a growing market.

Lead is known toxin. There are no safe levels of lead for humans; any amount is a bad amount.

Health effects range from mild health irritations and decreased fertility at low amounts, lower IQ and emotional/behavioral issues in milder amounts, and seizures, coma, and even death at higher amounts.

Top exposure pathways (aka: sources of lead) include:

  • Paint
  • Soil
  • Dust, created by soil or paint
  • Water / Plumbing

Lead may be in toys, cosmetics, food containers, and other places, but the above are the top 4 pathways. Paint is generally recognized as the primary source of lead. People talk quite a bit about lead in water, in part because of the crisis in Flint Michigan. Soil is a pathway that gets less attention; however, there is growing evidence that soil -- and in particular the dust that gets kicked up -- is a significant source of lead.

How to test for lead in your home or community

  • Test it yourself: Buy a product off the shelf
    • pros: This is probably the quickest path to testing.
    • cons: The results may not be reliable.
  • Test it yourself: DIY / Hacker methods
    • pros: Good for citizen scientists and teachers.
    • cons: Actually these don’t exist yet :( Help us create them!
  • Get a professional to do it
    • pros: Gets the most reliable results.
    • cons: can be slow/annoying if you’re working with your local gov’t or expensive if you’re paying a private company)
  • Partner with a local college / university
    • pros: Can be low-cost, allow for bulk testing, and help build important relationships
    • cons: Takes time to build relationships
  • Use a mail-in service
    • pros: Uses reliable testing methods done by professionals
    • cons: May not be as fast as testing yourself, costs money
