I should think that official advise re, disposing if small quantities would change, accordingly. if leaking into ground beneath the muncipal dump was thought to be a problem. ( Upon Googling, I found that Mr. Sinner’s advice comes from multiple official sources, and appears to be standard procedure) .
Unlike petroleum,nicotine is biodegradable, I imagine it would almost completely decompose before it found it’s way into water supply via slow leakage of small (non-industrial) quantities. My only concern with that was , as I stated, the plastic wrapping will not, and I do wish there were some way to avoid using that.
Regulations for industry are , ofc, more rigorous, for obvious reasons .If we were mixing on an industrial scale, then we would also be required to treat the water that we use for rinsing out our equipment as hazzardous waste! Now that would be flaming awkward wouldn’t it?
Another difference betwen nicotine and petroleum is that nicotine is naturally produced by various plants, such as nicotiania species, as a defence against insects, This includes a number of edible plants. Therefore nicotine does get into the food and water supplies by entirely natural means. Our ptoblem is not how to avoid nicotine getting into the ecosystem, but how to avoid unnaturally high concentrations of it, bearing in mind that it is considerably more tioxic. to aquatic creaures and insects than it is to ourselves . That is, it can be toxic to the environment in much he same was that farmer’s slurry can and does poison rivers, norwithstanding the fact that animals have surely shat since time immemorial! and shit is good for your roses nonetheless.
Intrigueingly , human beings are adapted to absorbing nicotine from our environment, even to the point of having dedicated nicotine receptors in our brains.! This , perhaps sufggests that the beneficial effects (which we have only jrecently begun to investigate) far outweigh any harmful effects, at reasonably low dosage ?
Nicotine might turn out be analogous to salt: essential in small concentrations but extremely toxic to both ourselves and our environment in high concentrations. We do need to have a sense of proportion about it.
