Chemtrails killing honeybees? High levels of aluminum found
Bees may be declining because they are suffering dementia compared to Alzheimer’s caused by eating large amounts of aluminum.
A scientific study found high amounts of aluminum contamination in bees at levels that would cause brain damage in humans.
Bees rely on their tiny brains to navigate to flowers to collect pollen and nectar to eat.
Researchers from the universities of Keele and Sussex studied the levels of aluminum in pupae – the bag-like form bumblebee larvae before they emerge as fully grown adults.
The scientists found that the pupae contained levels of between 13 and 200 ppm (parts per million).
To put it in context, just 3ppm would ‘be considered as potentially pathological in human brain tissue.’
Previous research has found when bees forage for nectar they do not actively avoid nectar which contains aluminum.
Researchers at University of Sussex collected pupae from colonies of naturally foraging bumblebees and sent them to Keele University where their aluminium content was determined.
Pesticide residues have been seen as one of the most significant causes of a decline in bee numbers.
But the researchers, whose work is published in the journal Public Library of Science One, suggest the possibility that this aluminum is also contributing to the decline.
Professor Chris Exley an expert on human exposure to aluminum, from Keele University said: ‘It is widely accepted that a number of interacting factors are likely to be involved in the decline of bees and other pollinators – lack of flowers, attacks by parasites, and exposure to pesticide cocktails, for example.
‘Aluminum is a known neurotoxin affecting behaviour in animal models of aluminum intoxication. Bees, of course, rely heavily on cognitive function in their everyday behaviour and these data raise the intriguing spectre that aluminum-induced cognitive dysfunction may play a role in their population decline – are we looking at bees with Alzheimer’s disease?’
The Alzheimer’s society advise that although aluminum was linked initially with Alzheimer’s disease in humans ‘the link has not been proven despite continuing investigation.’
