Fumes from leaded solder, rosin, flux, are on the order of 100x more harmful than lead free

  Can you provide citation? Leadfree also requires rosin and flux, no?

  Is the lead even in the fumes? The temp it evaporates at is much higher. I understand "lead-free" fumes are actually worse, but you should avoid all fumes regardless.

    There isn't lead in the fumes. The risk of lead exposure is all about touching the solder.
    • snvzz 3y ago
      Yup. That's what I understand too.

      Similar to lead paint, lead exposure is from lead dust primarily. Soldering produces lead dust, and it is relatively difficult to prevent further contamination Lead free rosin is less dangerous than leaded rosin, check the SDS data sheets

    >I understand "lead-free" fumes are actually worse, but you should avoid all fumes regardless. Read the SDS for any rosin available leaded and lead free. Lead free will have P260, leaded will have P261, a significantly higher risk. And P302 vs P301, and other additional risks.
