I am fairly new to electronics. As soldering equipment was freely available I had not thought there were health hazards from it. I have had some eye problems since I started on my project. Then on watching some you tube videos on soldering I found I needed goggles to protect my eyes and a fan to remove fumes. I now have a fan and goggles, but am interested if there are solders that are less toxic than others. Also if soldering is big time toxic or if it is a minor hazard.
