Probably already posted but I thought this was interesting and worth putting up.
"PG as Possible air germicide
Studies conducted in 1942 by Dr. Oswald Hope Robertson of University of Chicago's Billings Hospital showed vaporized propylene glycol inhalation in laboratory mice may prevent pneumonia, influenza, and other respiratory diseases. Additional studies in monkeys and other animals were undertaken to determine longterm effects, especially the potential for accumulation in the lungs. After a few months of treatment, no ill effects were discovered.[29]"
Propylene glycol - Wikipedia, the free encyclopedia
Of course this does not speak to long term side effects. But it's certainly intriguing.
"Environmental
Propylene glycol is known to exert high levels of biochemical oxygen demand (BOD) during degradation in surface waters. This process can adversely affect aquatic life by consuming oxygen aquatic organisms need to survive."
hmmmm.... so don't blow your vapor through a tube into your fish tank... Your plecostomus might starve.
