What is the ld50 of salt?

The LD50 (lethal dose for 50% of the population) of salt (sodium chloride) varies but is generally estimated to be around 3 grams per kilogram of body weight in humans. This means that for a person weighing 70 kg (about 154 lbs), the estimated lethal dose would be approximately 210 grams of salt consumed at once. However, individual tolerance can vary significantly, and factors such as age, health, and hydration status can influence toxicity.
