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."
