As the FF’s administration continues cutting agencies we need to tell parents that this is what he wants. Sacrifice your family’s health so they can have a bigger tax cut.

Joke: because of the lead.
Not a joke: holy WTF. The Guardian is no clown outfit.

Analytical chemistry is now exceedingly sensitive.

The major source of lead (and for that matter mercury) is the combustion of fossil fuels, in particular coal.

Burning wood that grew in the mid-20th century also releases lead, as a result of the incorporation of lead from leaded fuels.

Detection is different than being actionable. I doubt there are very few items of common experience in which lead cannot be detected. It was long a component of soder in residential plumbing.

I can (and have detected) detect radon in my basement from the decay of natural uranium in my soils. Although radon is thought to be the 3rd largest contributor to lung cancer after smoking and lung cancer, I'm not particularly worried.

While I would agree that mass insanity is clearly rising and may in fact be related in many cases to heavy metals, I suspect toothpaste is not a major player.

I wouldn't go full RFK crazy over this report.
