Apple seeds contain amygdalin, which can release cyanide when metabolized. The amount of cyanide in apple seeds is relatively low, with about 0.6 to 2.0 mg of cyanide per seed. The LD50 (lethal dose for 50% of the population) of cyanide varies, but for horses, it is estimated to be around 2 mg/kg. Therefore, ingesting a significant quantity of apple seeds could potentially be harmful to horses, depending on their weight.
This vary from apple to apple, and also very much between the type of apple. Most apples have between 8-12 seeds, but some have less, others have many many more. The amount of seeds may vary with the condition of the tree, and the growth year also. If it is a particularily bad year, then there might be more seeds and fewer apples. In a good year, the apples will be bigger and have fewer seeds.
10 doses of cyanide !!!!Potassium cyanide: LD50, Oral Rat = 6 mg/kg.Phorate: LD50, Oral Duck = 0.6 mg/kg (ten times deadlier for ducks than KCN is for rats.)
ld50 for lamotrigine
Hydrogen cyanide (HCN) was identified in cigarettes smoke but very probably the concentration is not important for health. Far more significant is the nicotine content of cigarettes. Nicotine is a deadlier posion (by ld50) and is also addictive.
True. The chemical with an LD50 of 1000mg/kg is less toxic than the one with an LD50 of 100mg/kg. LD50 is the lethal dose at which 50% of the test subjects die, so the higher the LD50 value, the less toxic the chemical is considered.

The radiation LD50 of most insects is far higher than the LD50 of mammals.
The LD50 of methanol for rats is typically around 5628 mg/kg. To calculate the LD50 for a 100 gram rat, you would multiply the LD50 value by the weight of the rat in kilograms (100 grams = 0.1 kg) to get an estimated lethal dose.
1mg/kg
A probable value for plutonium is LD50 = 5 μg/kg (cumulated chemical and radiological effects).
The LD50 of phenobarbital in humans is estimated to be around 15 mg/kg when taken orally. LD50 represents the dose at which 50% of the test population would die as a result of the substance.
A high LD50 (lethal dose for 50% of the population) indicates that a substance is relatively less toxic, as it takes a larger amount of the substance to cause death in half of a test population. In toxicology, a high LD50 value suggests that the compound is safer and poses a lower risk of toxicity compared to substances with a low LD50, which require smaller doses to achieve lethal effects. Therefore, when evaluating the safety of chemicals or drugs, a high LD50 is generally seen as favorable.
