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. -------------------- ###Top Resources on PublicLab.org Related to this Topic - [How to Test For Lead in your Environment](https://publiclab.org/notes/read_holman/04-11-2019/how-to-test-for-lead-in-your-environment) - [Evaluating Low-cost Lead Screening Products](https://publiclab.org/notes/read_holman/04-16-2019/evaluating-low-cost-lead-screening-products) - [Chemical/Analytical Methods Used When Testing for Lead](https://publiclab.org/notes/read_holman/12-12-2018/list-of-methods-for-lead-detection-monitoring) - [How much lead is legally allowed and what government agency regulates that?
