The material that causes death or severe illness when used, inhaled, eaten or touched in small amounts for just a small period of time are termed as the most toxic substances.
How do we classify most hazardous substances?
We can differentiate these fatal substances acute toxicity by a term called LD50. While LD50 is the amount of substance which causes the 50% death of a group of test animals. Usually mice and rats are used to test the LD50 dosage.
Generally, any material, even those that are beneficial, if taken in excessive amounts, may cause us harm. To clarify this, let’s take examples of cigarette and dry fruits like cashew nuts.
