Grams of substance per kilograms of bodyweight.

What is this heresy

[–] [email protected] 4 points 1 month ago

Well obviously written by someone who was brought up using imperial rather than metric.

But what ld50 means is grams per kilogram of bodyweight. That's what the poster is trying to say.

Google management suite.

The relentless muddling of metric with imperial measurements is not only bewildering but an absolute affront to rationality.

When dealing with the critical precision of LD-50 values, why persist with this nonsensical jumble instead of adopting the metric system entirely?

The table's careless presentation of 'gms/Kg' without specifying units in each entry is a grotesque oversight.

Is this some cruel American prank designed to torment and confuse the rest of the world?

I think if I ate 175 pounds of cured meat, the sodium isn’t what would kill me.

[–] [email protected] 8 points 1 month ago

Mmmmmmmm, 50,000 potato chips.

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.

Even tho i hate cupcakes the 100 one looks easy enough .

[–] [email protected] 4 points 1 month ago (1 children)

Definitely seems like the easiest one on the list, but I'm pretty sure you'd vomit before you got very far past a dozen.

Also the LD50 of 100 is for someone who's 150lbs. That's fairly light for an adult who's capable of eating a lot of cupcakes.

just clench your butt cheeks and power through!

100 frosted cupcakes

Man... I am so glad I don't like frosting.

These numbers look very questionable. Twice as much salt as alcohol to kill someone? I'm sorry but I call bullshit.

[–] [email protected] -4 points 1 month ago (1 children)

Salt doesn't do much to the human body.

[–] [email protected] 2 points 1 month ago (1 children)
[–] [email protected] 1 points 1 month ago

No, it doesn't. Wikipedia doesn't cite any credible source for that number, instead it links to a book, which doesn't cite anything.

LD50 for sodium chloride is 3g/kg. It is part of MSDS and is based on an actual scientific study.

It's time to update Wiki.

[–] [email protected] 2 points 1 month ago (1 children)

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.

[–] [email protected] 2 points 1 month ago (1 children)

According to Wikipedia, the lethal dose of table salt is 0.5-1g/kg, not 10 as stated in the post.

[–] [email protected] 0 points 1 month ago

Across what dose period between the two? A lethal bolus dose is smaller than a lethal two week evenly distributed dose.

Ohhh, Murikan units, fyi:

1 US quart (qt) = 0.946352946 liters (l)

So, not exactly breakfast, but a nice desert after dinner.

The thing I find hilarious about this is alcohol in the US is often measured in ml, and usually sold at 750 or 1500ml as opposed to quarts

[–] [email protected] 5 points 1 month ago (1 children)

Soda is in ounces until it reaches a liter. Alcohol is ml until you get to 40 ounces. Milk is always pints, half gallons, and gallons. Why?

[–] [email protected] 2 points 1 month ago

The real question is why US have fake pints?

[–] [email protected] 3 points 1 month ago (1 children)

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)

[–] [email protected] 2 points 1 month ago

US doesn't use imperial units, US is using US customary units, or something like that.

[–] [email protected] 9 points 1 month ago (2 children)

Quart of vodka my ass! We call that "breakfast"

Calm down, Lazerpig

[–] [email protected] 4 points 1 month ago

LD 50 is tested on animals so it's not quite a 1 to 1.

[–] [email protected] 3 points 1 month ago

Uncle Harry, don't eat that!
