Lead exposure is something I’m paying closer attention to right now.
Especially following the California wildfires.
When older homes burn, lead from paint, pipes, electronics, and building materials can be released into the environment.
These were urban interface fires, which means structures burned, not just vegetation.
We are also seeing early reports of elevated lead levels in soil in some affected neighborhoods, though findings are variable and still being evaluated. In some areas, a portion of residential soil samples have exceeded California’s screening thresholds, while other locations remain within expected ranges.
I am also seeing this reflected in practice, with more children in affected areas showing elevated blood lead levels than I would typically expect. This does not appear universal, but it is enough to be noticeable.
This is not something most families are thinking about, but it is relevant because exposure may come from dust and soil resuspension even after the smoke has cleared.
There is no known safe level of lead in the body.
Even low levels can impact:
👉 neurodevelopment
👉 behavior and impulse control
👉 growth
👉 gastrointestinal function
In practice, I may consider screening around 12 months, and rechecking in children who present with
👉 behavioral dysregulation
👉 constipation
👉 slower growth or short stature
Because sometimes what looks behavioral has an environmental component.
From a physiologic standpoint, lead can:
👉 disrupt neurotransmitter signaling
👉 increase oxidative stress
👉 interfere with mineral balance, especially zinc and calcium
Which is why support is not just about “detox.”
It is about reducing exposure and supporting the systems that help the body process and eliminate it.
Depending on the child, that may include:
👉 zinc
👉 calcium
👉 vitamin C
👉 NAC
👉 pectin such as modified citrus or apple pectin
These support mineral balance, antioxidant capacity, and binding and elimination pathways.
Environmental exposures are one of the more overlooked pieces of the puzzle.
If you are seeing changes that do not fully make sense, it may be worth asking what else could be contributing.
