Yes but lead particulate is going every where and if you touch lips, You’re ingesting it.

The primary means of exposure in a lab setting is through ingestion of particulate matter by getting it on your food or clothes -> mouth

Well, like I said I'm no doctor, but I don't know that I'd use quora to make medical decisions.

Here's an environmental safety article from MIT. It mentions lead oxide fumes from soldering. What do I know other than the required lab safety training.

It says that lead fumes are unlikely to be generated:

Based on standard soldering iron temperatures of 620°F-700°F and the melting point of lead (621°F), it is unlikely that lead fume will be generated during electronic soldering, unless the solder is heated to lead’s vaporization temperature of 3182°F.

Interesting that you skip right past the part that I mentioned about lead oxide fumes.

   "During the soldering process in the form of lead filler metals, lead oxide
   fumes are formed and excessive exposure to lead oxide fumes can result in
   lead poisoning."

It's right there and easy to read.
