The most direct way to address the metals issue is to not only sample
for the metals you know about but those that that you may not know about
that may be present in small quantities in the rods or the substrate
that could be released during welding. The easiest way is to ask the lab
for a "welding fume metal profile". The lab analyzes for all the metals
at once using ICP (NIOSH 7300) on each sample. The labs commonly report
the 13 metals listed below (some labs offer 26 metals).
Aluminum (Al)
Antimony (Sb)
Beryllium (Be)
Cadmium (Cd)
Chromium (Cr)
Copper (Cu)
Cobalt (Co)
Iron (Fe)
Lead (Pb)
Manganese (Mn)
Molybdenum (Mo)
Nickel (Ni)
Titanium (Ti)
Vanadium (V)
Zinc (Zn)
Hope this helps.

Actually I don't think these are the most serious issues. Chromium and
Nickel fumes are carcinogenic, and possibly Iron as well. You should
probably test for all the metals involved.

I will be monitoring welding fumes in our student welding bay and am
looking for suggestions of anything to look for other than particulates,
carbon monoxide and carbon dioxide.
Thanks for any suggestions...
