It’s an American. Ld50 is in g/kg. Quarts are our magic bullshit, but idk why they used it vodka is in fifths and handles (750mL/1.5L respectively). Table salt comes in a standard cylindrical container consisting of about enough to kill every other person that weighs 10.7 stone.
The only thing I'll defend here is cylinder, because we actually all get our salt in cylinders, so it's a legitimately useful comparison in this one specific instance
I think that one’s off. Ethanol has a LD50 of like 7.06 and vodka is also at around 40% by volume too. Also because I’ve cleared plenty of quarts before I stopped that.
I think there's also the amount in the body at one time to consider, I don't think many people aren't downing an entire quart of liquor in one straight shot.
Ah I got thrown off by it being a US unit as I know in the US for some braindead reason they call a pint a "half quart(er gallon)" so I was thinking 1.136 litres, but yeah the US decided to not even use the same imperial units as anywhere else which still used them at the time just to be extra special (and scam people into thinking they were getting more than they wore, which sets the tone for the US I guess)
Why would salt be more lethal than alcohol? You have a lot of water to displace to deal with it, and you can drink yet more water to do so as it will take a while to effect you.
Alcohol is just poison and the act of processing it does damage. Drinking water to dilute it is less effective as it kills pretty fast.
Technically, LD50 specifies a time of death within 2 weeks of the consumption. That is very relevant for some items on this list, but there you go. Also, Morton Tender Quick is 0.5% Sodium Nitrite so 1/22nd of a 2 lbs bag is enough to kill you and much faster and more reliably than 175 lbs of cured meat.
