There are tests specific enough for iron and lead, I am not so sure about zinc.

define "test"...

Do you mean adding a reagent and seeing a ppt or colour change, or can you stick it in an AAS?

you can directly use AAS or ICP using the same sample .
or if you want to do by titration you have to take a portion
of sample to identify the element you want
divided the same sample to parts .
