What's wrong with lead in solder? I wash my hands after soldering every time and I can't imagine how I'm really exposed otherwise. Professionals who solder long periods every day are far more likely to have adverse health outcomes from inadequately vented flux fumes.


There's nothing wrong with lead in solder. It's not going anywhere. The vapor pressure of lead at soldering temperatures is essentially zero, and in solid form it's about as bioavailable as neon.

As far as disposal is concerned, one car battery has more lead in it than every electronic device you'll ever own, but for some reason nobody cares about those.

(Yes, most car batteries get recycled... and that would have been straightforward and sensible to mandate for the rest of the world's lead-bearing electronics, compared to the nightmare that is/was RoHS.)


The most affected by lead are the kids, also the relationship to IQ decrease happens on infancy.


Oh cool, so I can be even more blase than I am.


As I understand it, the main issue with lead is disposal.


I think what the RoHS people really wanted to do was shut down lead smelters, which are nasty enough in themselves. They just used a nuclear weapon where a BB gun would have sufficed, and were indiscriminate about their choice of targets.

As far as disposal goes, there is some concern about lead in CRTs and solder leaching its way down into the water table and back up to our taps, but no one has ever demonstrated exactly how that happens to my satisfaction. I'll concede the point that it's best not to throw it away.


A mechanism that I don't even think was anticipated by the RoHS people, was that electronic waste was being shipped to third world countries, e.g., Europe to Africa, where people were burning the circuit boards in open air (perhaps assisted by kerosene) to collect and sell the metals.
