As kids we always used to keep a few air rifle slugs in our mouths, made for faster reloads and a bit of spit "seemed" to lube the slug and give it a bit more "oomph"!

30 years on and all the children we've sired have to right number of limbs and digits.

It's lead oxides and sulphates that are really toxic.
It's why white paint uses titanium oxide these days.
And red lead, that's nasty! I'm pretty sure it's banned everywhere.

As kids we use to play with mercury, roll it in our hands, coat pennies in it, and other fun stuff. Don't recall ever eating it, but who knows. At least I've lasted to retirement age, so I guess I won't let those new energy saving light bulbs scare me.  ;)

I don't know what's scarier: thinking about how someone determined this, or thinking about the fact that they probably got a government grant to do it...

Recently I've been cynical enough to wonder about blaming all those "inner city lead poisoning" cases on paint, when at the time Automobiles were universally burning leaded gasoline and (consequently) spewing volatized lead compounds into the air where it would have relatively easy access to the blood stream...

I've heard woodworkers and artists etc complain quite a bit about how unleaded paints just aren't the same.
(but "titanium" sounds so much cooler, don't you think?"

LEDs frequently contain arsenic, BTW.

No there isn't.
Simple as that.

Humor me then:
If lead containing solder is banned, because of RoHS, why can I go out to every hardware store and buy regular, lead containing solder?
Why can my company deliver products that are RoHS compliant (tested and tried by companies such as SGS and accepted by all major electronics suppliers on the market) but still use lead containing solder to get microcontrollers on PCB's?

Not all solder may contain lead, however, in some cases there is no feasible replacement.
There are actually quite some exemptions on RoHS.
http://www.rohs.gov.uk/Docs/All%20Current%20Exemptions%202011.pdf gives a list of all exemptions currently in effect.
See 7A and 7B for the solder exemptions in detail.

You're (officially) allowed to use leaded solder when repairing a board which was originally soldered with leaded solder.

And for hobby stuff you can use whatever crap you like :D
Leaded solder all the way (most of the time).

Absolutely. I did have a bit of fun trying to solder legs on a surface mount chip using leaded solder.... I think I should have used lead free on the chip & leaded on the legs, it might have worked a bit better
