Air or nitrox in forest?

[pisoiu]

Let's say I am in a deep nice and big forrest and I am doing my fills there with a compressor. What will I have in my tanks, air or nitrox?

 

[ajduplessis]

Neither, it would be Normoxic Nitrox

 

[pisoiu]

Well.. a lot of trees with leafs, photosynthesis, oxygen released...

 

[OtherHalf]

Nitrox 20.9

You didn't say if you're filling at night or during the day.

 

[pisoiu]

Ok, day, we have light and photosynthesis.

 

[ajduplessis]

21.2 depending on the exchange rate.

 

[jboneng]

As other had said: EAN21
Nitrox is any mixture of oxygen and nitrogen, air is a mixture of oxygen and nitrogen, so...

 

[Kharon]

Seriously???

It's an interesting question. Trees and anything photosynthesizing release O2 as a byproduct, so necessary to our survival, and something this human species takes for granted/is oblivious to. Just how much O2 *is* released by a large forest? Enough to read on an analyzer?

Oxygen Production: Trees vs Grass

How Much Oxygen Does One Tree Produce?

Tree Facts | American Forests

So of course no clear answer as there are many variables, species and size of trees etc. "one large tree provides oxygen for two people" which doesn't answer the question: would this show up on an analyzer.
