comma before and after adverb: air or soil adsorption, respectively,

[slavipet]

Hi everyone,
I have some problems with the punctuation in the following sentence: "Formaldehyde gets into plants through air or soil adsorption, respectively, through their leaf mass or their root system" - I have placed comma before and after respectively - is it correct? Or is one of the commas redundant?
Thanks in advance!

In order to retain your sentence as it stands, I think I would omit the comma after 'respectively'. Personally, I would reword it:
Formaldehyde gets into plants either by air adsorption (through their leaf mass) or by soil adsorption (through their root system).
I hope you don't mind my making this suggestion.
