Brass how safe is it to use? I've heard about brass containing lead in them.
I have a brass GP PAPS clone and a Quasar rda.

Brass can contain lead, or not. Free-machining brass often has lead as it makes it easier (faster and cheaper) to turn it on a lathe and mill it.
Because there is a huge range of brasses, it is impossible to tell which has and which hasn't got any lead in it. Cheap brass is more likely to have lead in it as that means they can reduce the content of the expensive metals (e.g. copper). Logically, a cheap brass clone is more likely to have lead brass than a $250 original.
Brass can be an alloy of:
copper and zinc
copper-zinc-lead
copper-zinc-silicon
copper-zinc-tin (low-quality bronze aka red brass or gunmetal)
copper-zinc-arsenic
copper-zinc-lead-arsenic (DZR brass)
There are so many brasses that any single answer is bound to be wrong. The question is, probably, if lead brass is used in my rba, should I be worried? Cheap brass anywhere other than the atomiser head probably isn't an issue. There will probably be more lead at the surface in a cast item, but these items are machined.
In the marine world, we tell if brass items have been subject to electrolytic corrosion by their color: a brass object that looks pink has lost some metals due to leaching out. For example, propellers are supposed to be made of bronze but are almost always brass, and if they are subject to corrosion they go pink. This means they are weak and will break.
Electrolytic corrosion occurs in the presence of an electrolyte (an electrically-conductive liquid) and an electrical leak. I'd say both are a very real possibility in an atty
)
So from a practical perspective, if the internal surface of your brass atomizer goes pink then it's lost some metals, and that might include lead. Otherwise don't worry too much. If you sub-ohm, or vape 10ml of liquid a day or more, or vape creamy-custardy refills, then you've probably got more problems to worry about than a few nanogrammes of lead
Also note that if instead the surface goes green, then that's a copper salt and should probably be left there and not cleaned off as it's protecting the surface (like a green copper cathedral roof).

Brass can have lead and zinc in it. Should use atty's that the inner part is Stainless steel. The air flow ring can be brass or copper but not the inside.
