I have a couple of question regarding the use of formaldehyde as a
fumigant, I would be very grateful if anyone could help me with these:
1) How do you convert a concentration of formaldehyde vapour expressed as
mg per cubic metre into ppm?
2) Is formaldehyde vapour heavier or lighter than air, i.e. does it tend to
sink or rise?
Thanks for any help.
