I think the earlier post to review the ACS materials and other references was right on the money. Consider the type of welding, materials involved (you should have MSDS for your welding rods or wire) then consider the gases, metal fume, UV light etc in your approach. These ultrafine particulates with adsorbed gases are not good so be sure there is good capture ventilation at the source where possible, not just a ceiling or wall exhaust fan. Look closely at silver solders and stainless welding to adequately address things like fluorides, cadmium, chromium and nickel.

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