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.

Chromium and Nickel fumes are carcinogenic, and possibly Iron as well. You should probably test for all the metals involved.
