| median lethal dose |
50 ) The statistically derived single dose of a chemical that can be expected to cause death in 50 per cent of a given population of organisms under a defined set of experimental conditions. This figure has often been used to classify and compare toxicity among chemicals but its value for this purpose is doubtful. A commonly used classification of this kind is as follows:Category LD 50 Orally to a Rat (mg/kg body weight)Very Toxic: less than 25 Toxic: from 25 to 200Harmful: from 200 to 2000. ...
