Yes, i reckon it would
depend on where the wound is!
Your information on arsenic residue is very interesting. You say that 2 of the 9 blades you tested had levels as high as 0.35 mg/L. What was the lowest level tested? What was your average result? Considering that much
larger doses taken internally
are necessary to cause death, why do you feel that these levels might cause adverse heath effects? Using the Merck test it seems that you draw the arsenic off into the suspension water. How long does this process take? How would arsenic in any significant amount be absorbed or ingested by the body through normal handling of a blade? Would the arsenic residue on the blade be naturally inclined to be airborne? Barring being cut by or licking the blade how would arsenic residue on a keris actually get into the human system in significant amounts to actually cause health problems?
Thanks in advance for addressing these many questions from a scientific layman.
