Right but what folks miss is the "lead" in that solvent contained lead oxide....
Lead by itself in the body that isn't oxidized does very little damage, well apart from when it enters by traumatic means. Which is why they don't go after bullets, or shot, when it's deep in the body. It doesn't poison the person. Once any infection is ruled out, pellets or bullets are often carried around by the "victim" for decades until they pass from other natural causes.
There seems to be some anecdotal evidence of the absorption of powdered lead through skin, however small.
What's unknown is how much of any absorbed lead is actually stored in parts of the body such as in the bones and tissues.
Testing was done with different types of lead including that type in lead paint which is water soluble.
And some of the test subjects were rats.
The minute amount of metal powder absorbed through their skin was detected in their urine as proof that it was being absorbed.
But you're probably right that it's not the same as actually being poisoned.
I only searched for skin in this US Dept. of Health document by skimming through to pages 261 - 262 where some of the test results were mentioned. --->>>

The next section p. 263 mentions autopsy studies of children and adults about where lead is stored, in bones and soft tissue.
Apparently most people come into contact with much less lead today than during previous decades.
The gov't also claims that:
"
Washing skin with standard
soap and water is not enough to
remove lead residues. NIOSH researchers have developed wipes that can
remove 98% of
lead residues from skin. ... Shower and change your clothes and shoes after working around
lead-based products. " --->>>

I wear thick latex dish washing gloves when I ckean my revolvers in almost scalding soap & water.
Not because of the lead which never really occurred to me, but because I don't want to burn my hands.
