Heavy metals are a pretty special case, which is why they have always been categorized as their own thing.
The only reason we have "safe levels" of lead is because it's a naturally occurring metal that's found in trace amounts literally everywhere.
Also fun fact radon decays into lead, often lint traps and clothing have (barely) detectable levels of lead above what you'd expect since dryers are often in basements which all have some level of radon.
You could drive yourself up a wall trying to completely eliminate your exposure to lead.
