well, that depends on how much liquid you vape per day.
according to Dr. F, the "acceptable limit" of AP is between 182-638ug per day. (depends on ventilation and amount of activity)
Diacetyl is even lower than that, between 86-302ug per day
so if you vape 10ml per day of a liquid that contains 100ug of ap, you are at 1000ug for the day. some of the really high liquids out there, will put you over the daily limit by just vaping a single ml.

Thank you! Ok, so if I vape 1 ml of TPR's Cinna Drizzle (AP: 21.5 ug/ml) then that's not considered high?
GLV's results seem to be formatted a little differently. Their results (for example) show Red Berry at 0.006 mg/ml Diacetyl and 0.089 mg/ml AP. Am I reading that right? Stuff like this makes my head spin
@Dizzo maybe you can add "desktop version only" to the vapor shark note on your spread sheet? I was checking all the links on your list on my iPhone over the weekend and noticed they were the only one that didn't have links to testing. Sent them an email asking were they were and received a response today saying they can only be seen on the desktop version. Too bad their mobile version doesn't have a link to the desktop version! 
A "ug" is a microgram. There are 1000 micrograms in a milligram (mg). So, if you multiply 1000 X .089, you get 89. There are 89 ug/ml of AP in the juice you referenced (and 6 ug/ml of Diacetyl). Hope this helps!
The full text of the article you linked is behind a pay wall for me. do you have a different link perhaps ?
How does ventilation and physical activity impact our exposure as vapers when we are directly inhaling into our lungs. I believe those numbers have to do with factory workers. Ventilation in the work place and their level of physical activity impacts their exposure to DA/AP in ambient air.
see attached file.
i'm no scientist, you will have to ask Dr.F on that one. if i had to take a guess though.....
the ventilation determines the amount of fresh air you are getting. fresh air is better for the lungs? i mean think about it. if you spend all day vaping in a tiny room VS. vaping outside, don't you feel differently? all that secondary vapor might not be bad for you, but i'm sure it's not as good for you as fresh air.
activity effects the amount of inhales/breaths you take per min. so lets say that in a one min period of time, you take 45 breaths with 0 activity, and hit your vape 1 time. so the ratio of fresh air to vape air is 1 in 45 per min.
if you are breathing heavily, lets say you take 90 breaths, and hit your vape 1 time. now the ratio is 1 in 90.
so less of the overall air you intake per min is vapor. it's about the ratios imho.

Sorry I haven't had time to update. Baby busy! I'll try this weekend. In a week or 2 I'll have another person on the team

That's one outstanding excuse Dizzo. Nothing in the world like expanding the team. All the best!
Lol
Just to clarify, it may have not come out right.
My son is 8 months. What a handful!
In a week or 2 there will be another person with edit ability on this list

found this company called "TBD liquids" (the best damn).
seems they test and most are D/AP free. they seem to have good prices too. surprised i have not heard of them. anyone try them before? any good?

So, what is 'Diacetyl' and '2,3-Pentanedione'?
Yes, I googled them. And I received very technical definitions.
In laymans terms, what are they, and why are they bad?
Thank You

very layman terms:
they are chemicals that could possibly cause popcorn-lung (very bad), and good tasting juice can be made without them.
if you buy liquid that has D/AP, you are taking an added risk that you shouldn't need to take.
So this thread basically consists of the "organic" consumers in the vapor world. I don't have anything against not inhaling harmful chemicals, but could it be that all of us in here are being paranoid?
What are the effects of "popcorn lung" and how often does it occur?
Also, if I wanted to avoid D/AP, is the only way to buy juice online by companies that lab test?
organic is not the same as D/AP free. organic liquids can have high levels of D/AP
possibly, but i have always been a "better safe than sorry" kind of person.
not sure of all effects, but a lung transplant is the only way to get rid of it. just google it.
hasn't really occurred yet in vapers, but we are looking to the future, and long term effects. vaping is still pretty new. we don't know what are lungs will look like in 30+ years.
look at smoking for example. we know it's bad for you, but many people smoke for 20-30+ years before something bad happens.
pretty much. anyone can say the have D/AP free liquid, but without proof.....it means nothing.
Thanks for the response Gauntlgrym 
I'm definitely a "better safe than sorry" person as well. I will look into D/AP free juices.
Very true. We are all test rats.
My gut instinct, which has never steered me wrong, tells me that vaping certainly will result in some type of ill effects in the far future, but they will be manageable.
