All of my opinions and suggestions are based on my five decades of actual beekeeping,
not so much on book learning, watching YouTube videos nor reading internet sites.
I've always use treated lumber for my stands with no problem. IMG_0281.JPG
I wouldn't even blink using treated material. All my hives are on stands that I've made with treated lumber. Even if there was a small amount of chemical rising off the wood I think it would pale in contrast to the amount of chemicals the bees are exposed to when they forage and in the foods they bring back to the colony.

My opinions are based on whatever OD Frank says because he thinks he knows everything!
Beek 58 yrs. Would not use treated wood at all with my bees. The effects are extremely subtle. More susceptibility to diseases, general weakness in productivity in comparison to the prior usage without treated wood. Been there done that with over 350 hives. The best advice offered is to use cinder blocks or bricks. As you will grow older, your strength to remove the heavy supers will diminish noticeably, the higher the stands the more difficult it will become to remove the heavy supers. The lower they are the more you will be able to avoid extra help for just a little while longer. OMTCW
I don't know if these products would work for ground contact, probably not. However for all other wood supports, hive bodies, etc this is, I believe, great stuff.
We have used both,
TALL EARTH ECO-SAFE WOOD TREATMENT
ECO WOOD TREATMENT
They come in powder form, about $20 for a bag to make 1 gallon. Mix with water, seems very thin in the application and runny so you can't load the brush up, take your time in applying while listening to "Inna-Gadda-da-Vida". It may look like you haven't done a good job. Don't worry, just be sure you have fully moistened all surfaces, let it dry for a day or two. Once out in the sun and rain, will begin to take on a most interesting tinted patina and finally "aging" to a dark tone that highlights the grain of the wood. Have used it for years.
As with all advice, look it up, do your research and be sure you are comfortable with what it is. I believe it is quite safe for bees and does not need regular reapplication for a long time.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
LOL, been a beek for 58 yrs. am 83. Have noticed that the bloom on wild fruit trees and other blooming trees has increased quite noticeably within the last decade, maybe simultaneous with the human depredation of the Amazon forests ("The Lungs of the earth" as my fourth grade teacher used to repeatedly tell us). Increase in CO2 resulting. Older orchardists must be noticing this phenomena. OMTCW
I can well attest to that increase in gravity, I've observed it myself. There are many things that were an easy one hand pick up when I was in my early 20's, and today as I turn the corner past 60, they are two hands and a grunt to pick up that same item. I consider that definitive proof that gravity has gotten much stronger over the intervening 40 years.....
