"EVERYTHING IS POISON WHAT VARIES IS THE DOSAGE"
A very old quote but still true nonetheless.
However, fear of toxicity has reached hysterical levels about some things.
I fault no one for being prudent but banning lead because it is lead is past prudent and into hysteria.
Restricting or banning ATVs because they have lead in their paint and lead acid batteries has been proposed (not sure if it actually passed anywhere)
Are children going to eat the paint off an ATV?? Unlikely, I think.
Lots of things are regulated to some degree, but its not consistent and not always smart. Silica dust is a listed hazardous material, but only if your workplace buys it for use. Silica dust that blows in off the desert is not.
Table salt is composed of hazardous chemicals, but is not a listed chemical hazard in the workplace, its a "food". (it may be a "health hazard" but that is a different list
)
Even water is hazardous under certain conditions.
No, I don't lick my fingers after cleaning primer pockets, why go looking for trouble??
