Lead (Pb)

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 a known toxin for humans. 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, paint, or emissions)
  • Water / Plumbing

Lead may also be in toys, cosmetics, food containers, and other places, but the above are the top 4 pathways. Paint is generally recognized as the predominant 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.

There are no safe levels of lead for humans; any amount is a bad amount. Lead is also bioaccumulate which means that it doesn't leave your body. Small amounts add up in your body over time.
