Aluminium nano-particles stunt plant growth - paper


Closed Account
New Zealand's favourite chemtrail hunter has recently noticed a 2012 paper titled:

Effects of Aluminum Oxide Nanoparticles on the Growth, Development, and microRNA Expression of Tobacco (Nicotiana tabacum)

Which concludes that if you increase the amount of aluminium "nanoparticles" in soil you can affect the growth of plants.

as far as I can see there is no discussion in the paper as to the well known effects of aluminium toxicity and the pH of the soil being used is never discussed. Instead they postulate that:

The results of this study show that Al2O3 nanoparticles have a negative effect on the growth and development of tobacco seedlings and that miRNAs may play a role in the ability of plants to withstand stress to Al2O3nanoparticles in the environment.

The paper seems reasonably argued - but I have little knowledge of the subject and was really looking to see if they addressed known Al+++ toxicity, so any one who has any insights in this I would welcome their comments.
The obvious 2+2=5 conclusion that chemtrailers looking for their big "A-HA!" moment is that as they "know" we are being sprayed with aluminium (and other) nanoparticles to reduce crop yields and ruin our purity of essence, then this paper proves that this is why they are doing it.

The stand out thing for me here is how the plants were exposed to the nanoparticles, which was by mixing them in to the growing medium. Unless aircraft have worked out a way of not just covering crops but getting it underneath foliage and mixing evenly with the soil to guarantee uptake through the roots then it doesn't really support the supposed underlying purpose of the alleged chemtrailing activity. Lab conditions and real world conditions are two very different things.

You'd also (as they kind of point out) have a difficult time working out which plant growth rates were influenced by natural aluminium levels in soil (particularly in clay rich areas) and which had been influenced by your expensive and highly inefficient chemtrailing activities!

I haven't read the report yet but the issue of the direct effect of nan
o particles on growth and the effect of Al+++ ions on growth are different issues. In acidic soils as mentioned freed Al ions inhibit root development. This paper appears to address the issue of bio available Al which would be taken up by the plant irrespective of soil pH.

The paper also makes no link with any kind of atmospheric spraying of such nanoparticles:

Nanoparticles are heavily used in an industrial setting because they can be used to manufacture lightweight, strong materials as well as acting as pigments in products such as paints, sunscreens, and cosmetics [1]. Because nanoparticles have a large surface area to volume ratio, the use of nanoparticles in both industry and daily life is greatly increasing in realms that include advancing the quality of everyday materials and processes, improving the function of electronics and information technology, allowing more sustainable energy applications, and acting as key players in environmental remediation applications [1].

Those "environmental remediation applications" are not referring to geoengineering. If you follow the reference to the National Nanotechnology Initiative, this is clear:

... the development of technologies for remediation of toxicants in the environment. The institute’s largest investment to date in this area has been through the Superfund Research Program (NIEHS 2013b), which has awarded grants to scientists seeking to use ENMs for environmental remediation. Outcomes of these efforts include a “nano-towel” designed to capture mercury vapor (Johnson et al. 2008), nanoscaled iron particles to enhance water cleanup (Lee and Sedlak 2008), and nanoparticles that can help degrade chemicals such as polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and polybrominated diphenyl ethers (PBDEs) (Lewis et al. 2009; Xu et al. 2009).
