I agree with Mark that metals are probably of more interest than the
pollutants you mention (manganese is another potential metal of interest).
You might be able to use one sampling type for ultimate metal analyses of
several metals, but you will probably need a separate one for hexavalent
chromium.  Which metals you focus on may depend on what is being welded
(e.g., stainless tends to have higher Cr content than most non-stainless).

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=85****
