This is not a debunk (or is it ?).
This study is being used by chemtrail believers for further validation of their suspicions of an aluminumo-toxic environment. They might call it "more proof".
I can't dispute what the study finds, but the study is not without it's problems....mostly in the form of curious and assumptive statements which are in-turn being repeated on social media.
And then there is the bias of it's first-named author. (more on that later)
Bumblebee Pupae Contain High Levels of Aluminium

(bold text, by me...)
....really ?....not CO2 gas ?.....not vehicle emissions ?.....not any other of these ??
Interestingly, the study does give a reference to that statement (ref. #5)....that being another study by this study's (same) author, C. Exely.....
Sure, in high enough doses AL can be a neurotoxin, but the scientific consensus is that AL is not significant cause of Alzheimer's. This study in question has a different opinion, probably because the first-named author of the study (Christopher Exley) wrote a book on it.....
Aluminium and Alzheimer's Disease
This study I suspect, will keep popping up as evidence-fodder by suspicious people, because it encapsulates a few controversial alternative media subjects.....
Alzheimer's
Bee decline (even though it's about bumblebees)
Chemtrails
.....even though the study reaches no definite conclusions.
It uses small sampling, no comparative studies, and the results themselves are "not significant".
The study (it's a small study, nearly an "article") affirms my above sentence....
But they did, and the press is loving it, with eye-catching click-bait titles like....
"Are Bees Getting Dementia ?" (CNN)
"Are Bumblebees getting Alzheimer's ? (Discovery News)
What about those poor earthworms, who live in dirt, and will eat "aluminum contaminated" soil in order to burrow ? I wonder what the Alzheimer's rate in worms is ?
On the chemtrail front, Dane Wigington and Russ Tanner are hot on it, in their style, "we'll-quote-scientific-literature-only-when-it-agrees-with-our-opinion"....(and if it doesn't, "the science has been faked").....

(see 12:30 - 13:30 in the mp3)
When quoting the article, they both get the study's PPM and PPB results mixed-up, finally agreeing that this doesn't matter,
Actually, the numbers in this study are in PPM, not PPB, so they are higher than what they "whatever-agreed" to (which was PPB).
The study uses dry-weight results, in the term ug/g, which is 1 ppm= 1 ug/g.
