Metals in Hemp Oil - Details

Hello Future Folks, I wanted to share my current train of thought regarding metals found in hemp extracts. I hope somebody with more knowledge than I can chime in and help take this discussion somewhere. Issue: Heavy metals found in concentrated oils (ie. Pb, Hg, Cd, and others). These bioaccumulate to toxic levels. note I hear that cannabis is a good candidate for cleaning up radioactive areas like Fukushima. Cannabis is great at sucking up heavy metals from its environment, even Uranium, a…

Removal of heavy metals

Hey All. My boss has been asking me alot lately about running trim that has failed testing, the 3 most recent are pyrethrins, arsenic, and cadmium. I am wondering how to filter these things out of the hash (hopefully inline). iv heard of filtering through magsil but Iv also seen that magsil only works to pull out water soluble containment and everything I listed is not water soluble. I know the traditional way is to use a chromatography column but I do not have one, nor do I know how to opera…

Heavy metal contaminated product remediation

Have come across lots of heavy metal contaminated biomass in the market now that we are independantly pretesting all biomass prior to purchase. The problem, at least in my small sampling from reputable farms, seems to be an epidemic from my vantage point. I now have a problem with a shortage of material to run and am wondering about techniques for removing heavy metals. I am a little familiar with pesticide remediation but have no clue about the removal of heavy metals. Will distillation alone …

Heavy metals remediation thread!

hey there yall first time I seen any heavy metals in a hemp COA, on a batch of crude I extracted with cryo-ethanol. I’m always up for a challenge and I’d like to be able to fix this for the farmer. Cadmium. 0.21 mg/kg Cadmium is a wonderful source for red pigment, you’ll recognize it for the vivid hues of orange, yellow, and red found in Van Gogh and Monet’s paintings. It is also unfortunately a product of phosphate based fertilizers and is readily absorbed by hemp and cannabis, and is a w…

I can’t help you with the extraction side, but on the cultivation side there’s a few things you can do-

Calcium like gypsum helps displace the ionic charge in soil with metals like aluminum that can cause toxicity.

(shameless plug) The best solution is a fulvic acid supplement used as a foliar and drench that helps increase the CEC that the plant only uptakes and retains minerals and elements that it needs for growth. Depending on the farm size this can be done with compost or a bulk humate to a lesser extent.

big feilds, no use if its not clean! i will advise the farmers. thanks bro

[Lodawg]

i should be mining metals apparently

@Lodawg

i should be mining metals apparently

No, it’s awful. It’s bad for your health and unless you own the mine outright, it’s not worth the money. Just like F4200, there’s better money in reclaiming product that would have gone to waste.

[Lodawg]

just kidding bro, need to clean it up is my biggest prob.

[NewLevelProcess]

Call it platinum swazi

When they ask about the name change subjects

[Lodawg]

its not so easy anymore hahaha most of it is exported and for medical which i wont F with

[bigbone]

Those values are actually pretty low. Just fractions of the warning level. If I am reading it right, the ones with OR next to it are actually too low to reliably quantitate.

Won’t the FA allow those heavy metals to be complexed and therefore become soluble/bioavailable? The plants can’t really choose between which cations are absorbed (this is the basis of poisoning plants with excess sodium). At least this was my understanding.

[AgTonik]

I actually asked our CSO about this. I can’t find the e-mail explaining the mechanism, but when it is chelated (not complexed), it can absorb needed nutrients while flushing out heavy or un-necessary elements like metals. It doesn’t act like a simple MAOI inhibitor. It’s pretty amazing.

EDIT: Forgot a word

Hi,
First step is to deal with the metals in the soil, you might try redissolving the resin in a non polar solvent and running it through some bentonite clay, use pressure filtration.

[Apothecary36]

I think some centrifugation of the isolate could be a route as well correct?

[SidViscous]

Probably need to dissolve it and use some sort of flocculant to pellet with. This is one of the reasons we got out ultracentrifuge but then we never had any HM issues lol

[Soxhlet]

At the rcf you would probably pellet the cannabinoids as well. The other question is how cleanly it can be decanted.

[SidViscous]

That’s the other thing we were hoping but it didn’t work as well as I’d predicted. Then again we were using the blackest, shittiest crude the world has ever seen so we may have just not been able to see the bands lol

[Soxhlet]

did you run lc/gc on the pellet vs the supernatent?

Love Swaziland. I can’t imagine that the market there is all that big though? SA is a huge country. If it’s only the teeny lil country of Swaziland that’s getting they’re britches in a bunch then how much does it hurt?
