Tony,

In the dim echoing corridors (I'm really streching the nurons here) I seem
to remember that Castel's copper method will also work for arsenic but it
would be nonspecific.  This would also be the case with metelothionin (sp?).
 Now I know that someone is going to ask me to find out more info on
Castel's method ......don't expect a quick reply as I'm slammed for the next
few weeks ;-(
