I'm always careful to wash my hands after soldering, as well as keeping solder related paraphernalia away from kitchen utensils and food, anything like that.
Today I noticed how much it's possible to actually get on your hands, in fact if you rub a piece of solder onto your finger it leaves a dark silvery deposit - very worrying! Not sure how I've never noticed this, because I've done a lot of soldering over the few years I've been into DIY. Even worse is the process of unblocking a solder sucker, you inevitably end up with the same deposit on your hands
I wash my hands thoroughly but occasionally a tiny bit of greyness remains (mostly because I've had to empty the solder sucker, rubbish contraptions really), in the past I've probably mistaken this for the lubricant in the sucker but maybe it is actually solder
If that's the case I've eaten with a tiny bit left on my hands (although it's bound to have been in the microgram range)
You don't really hear about EEs getting lead poisoning so maybe a bit of lead on your hands isn't THAT bad if you wash it off? Fishing weights or air rifle pellets are far worse for leaving deposits on your hands (as well as being entirely lead) and I bet loads of fishermen have handled them and had their sandwiches right after!
Please tell me I'm worrying excessively, I really don't want to get lead poisoning, especially since I love playing with electronics so much!

I've not noticed this deposit on my hands having used typical 60/40, I always wash afterwards with pump soap and water anyway.
I think if you're worried a simple solution is to wear latex surgical gloves while soldering, on the solder feed hand anyhow. Not too expensive, can probably be re-used lots of times for this, just don't put them on inside out by mistake!

It doesn't appear with normal handling, but it was something I noticed after feeding solder through my finger and thumb

My 65 year old boss constently tells me stories of how he used to chew on lead solder and use his mouth as a "Third hand"... hes still alive. As mentioned if you are that worried then upgrade your iron if you have to and get lead free solder, laytex gloves couldnt hurt. make sure your room is well ventilated. I just built a new home with a 6" movable exhaust fan going to the outside... yes I customized my work lab, 3 seperate electrtical branches so if i blow a breaker i dont wreck anything else.

What I noticed is that lead free solder chews tips, the best of them, and if it isn't the metals, the fluxes used aren't any more fun to inhale. The buzz is different, but not any more fun. As a result of the tip problem, I use a regular 25 watt iron with a 16p nail press-fit into the heater, filed to a blunt pencil tip. The holder for that iron has an aluminum flashing shroud to trap the heat, and it gets plenty hot for the solder but the steel tip limits application to mainly SMD without thermal traces. This is OK, because that's all I really use it for. I use steel wool to clean the tip, and since 2006 when I got my first roll of SN96.5 AG3 CU.5 with 275 flux, the tip is still in perfect shape. Steel wool had been used to clean solder irons of all types for ages, but with the steel tip and lead free solder, there's no worry about tip wear or highly toxic solder particles all over the place. It is, however, fairly messy. It's a lot cleaner if you make a small box to put the steel wool into and periodically empty it out over a trash can once in a while. Number 0 steel wool works well enough.
For heavy connections, slightly dirty connections, or those likely to get re-worked a lot, you can't beat tin/lead. I still have rolls of all different fluxes and a few different brands. If I have to work in an enclosed area and need tin/lead solder I go for the Kester 44 flux. Some of the stuff Ersin makes will scramble your mind for a day or two if you sniff too much of it. I have a roll of .015" that I use for re-touching SMD's and if I get lazy and start using it for anything else indoors it puts me in a real bad mood and gives me difficulty thinking and a weird headache. I don't know if it has anything to do with impurities in the metal or the flux in it. I don't actually know what flux is in it because the label fell off long ago. I just know that stuff sucks.
Anyway, if you wash your hands and don't eat solder flakes and balls, the smoke from soldering is likely to give you the biggest trouble. I take everything outside unless I get deep into scope-time. After you get everything wired in and probed out it becomes impractical to take it outside for soldering. A vent hood would be most excellent. Just another project I've never completed.

Hi,
children are particularly susceptible to lead poisoning. It's something to do with the process of growing and the way it affect connections in the young brain.
Adults are much more tolerant, but there must be a limit.
The combination of adulthood tolerance and adulthood practice (no fingers/bits of interest in the mouth) makes lead poisoning almost a nil problem.
ROHS was probably never needed.
Lead free gasoline was probably never needed.
I wish the reporting done by our press could be less biased when dealing with green issues. That is our problem!

When I solder with the traditional 60/40 solder, I use to drink a glass of milk after the sodlering and of course wash the hands. But if I am soldering intense for more than 1 hour and a half, i take a break and drink the glass of milk after about an hour.
But im not really scared of using Lead solder anyways.

srsly?
No scientific grounds for this ,but i believe the people who are the most worried about getting illness and sanitising every last thing are the ones who get sick the most.
Next scare tactic will be "beware of breathing in to much of your partner/housemates fart. these gasses are dangerous to your health!!1 ,also helium baloons = death
like with everything in life too much of anything is not good.
Chewing on a piece of lead won't kill you. But eating 100grams per day will be bad.
I am still waitng for the calculation of all the extra power used to run all those reflow ovens and soldering irons at 380C instead of 300C and how that affected worldwide carbon emissions compared to using lead.
Please don't say i'm ignorant of global warming , i'm not.

Although lead poisoning is possible, especially in childhood like Andrew T said and when lead is a part of some biochemical compounds that are easily absorbed, i think that maybe there is some exaggeration around lead. Soak up the sun all day in a beach, is far more dangerous (skin cancer!).
I have a neighbor that has an old house, he changed water pluming a year ago, because it didn’t stand modern water pressure. The pluming was made of “lead” ( a common kind of water pipe, more than 50 years ago) and they drunk and cooked with the water coming out of them, for his entire life, such as all family. I never heard of special diseases in the family. That doesn’t mean “lead” is a good thing.
I used leaded solder too, for 35 years.
… well, sometimes my wife says I’m a crazy solder addicted… maybe lead is the culprit.

I have been soldering with lead for over 65 years. I have been subjected to major rf fields for over 60 years. Many electric shocks up to thousands of volts, and rf burns. Still waiting for the axe to fall; my health is better than that of anyone I know. I lift major weights at the gym, and play jazz gigs and repair electronics stuff and do all my own yard work. I don't know what's going to kill me, but all these things have had their chance and didn't succeed in doing me in.
It was, it is. Lead destroys the catalytic converter that cleans the exhaust. The cats are expensive and kind of a pain, but they do make a difference.
Lead? Hazard?
I teethed on lead paint. I had a rocking toy that I chewed the bar on, definitely had white lead paint. My toy trucks were painted with lead paint I used to scrape it off with my fingernail. My SAT score was 1496. Imagine who I could have been had I not damaged my brain at an early age. I think modern parents are looking for an excuse why their kids develop slowly when they don't talk to them and sit them in front of the television. My mother had me talking sentences at a year.

back in the Viet Nam era some GI's used a refrigerator shelf to grill some hamburgers -- they all got cadmium poisoning -- i don't think any of them sued GE or GM.
if we put tetramethyl lead back in gasoline there would be a net increase in fleet economy of somewhere between 6% and 10%. the unfortunates in the inner city haven't had educational attainment improved that much with the elimination of leaded gasoline.
