[Stoves] Metals in biofuels

[frank]

Dear Stovers, charcoal makers and brick makers,

Of the list of elements below I am wanting to know the ones that would 
be of interest in regards to causing problems, volatile toxins and of 
nutrient interest.
I have already added As, Cd, Pb, Zn, to my list for possible toxins.
I have added Ca, Mg, K, P for possible nutrients in left over char and ash
I have added Na, and K that may be problems in making an ash that  forms 
blocks (?).

Any comments of problems or concern or interest of the following will 
help me to put together a test program for testing biofuels.

Thanks (again)

Frank
