Ingesting gasoline is deadly in far smaller doses due to something called hydrocarbon pneumonia. My dad very nearly died as a result of having a tiny amount get past his throat while siphoning gas to a small engine's tank.
If you must siphon gas, go buy a cheap "pump siphon" from Canadian Tire.
It doesn't take into account so many things, and it's extremely misleading.
Most of these chemicals don't ever appear in products in their pure form, so there's so much here that simply isn't relevant.
There's also consideration here that everything is by weight, and it makes sense to create that as a standard, but many of the pure forms of these items are far more dense than you would expect. One that stands out is uranium. A gram of it would be incredibly small, approximately 0.05 cm cubed. 1 lb is around 1.45" cubed (for my American friends).
So it would be an insanely small amount. Meanwhile water is insanely light by comparison. While also safer per gram, so it's an insanely large amount of water before any damage can be done while a relatively small rock of uranium can tear your DNA apart.
The whole chart is wildly misleading. It might be accurate, though, I have no idea if it is, but the fact is that it makes it seem like normal every day compounds like vitamin B will kill you at lower doses than uranium. While technically true based on weight, it makes uranium seem relatively safe by comparison and bluntly it's not. Even the smallest amount of pure uranium, which this chart would regard as "safe", would cause you to become incredibly sick for a very long time.
I hope nobody gathers "new" information from this chart and decides to do something stupid; but honestly, there's a lot of idiots in the world, and if anyone is that dumb, I wonder if the average intelligence of the planet might increase a bit.
This looks like a quite useless guide. All these substances appear in vastly different doses in the environment, so it in no way shows what is more likely to kill you or accurately shows what you are supposed to be careful with.
It really takes that much gasoline to be lethal? You mean to tell me less THC is needed to kill you than drinking gasoline? It's almost 10 times as much!
What's the denominator here? Like water is toxic at 90g/1kg, what's the other 910g? Because I definitely drink over a litre of water a day and I'm doing fine.
Tylenol is easier to overdose on than NSAIDs. I really don't think this guide is accurate. I'm really questioning the placement of cocaine and especially ketamine. Vitamin D from the sun? Lethal? I don't believe black widows are that venomous, either. How are they even measuring this? Cocaine will give you a heart attack, Tylenol will shut down your liver, venom acts like an infection... are they basing lethal dose on how much it takes to cause some kind of fatal reaction, or under a controlled administration with a defined "fatal dose" based on a specific measurement, like damage to a human cell?
Technically speaking, if the water is pure enough it can demineralize you and kill you over the course of about a week. UPW or HPW are often used to describe these substances, created in specialized labs or equipment for industry use.
