Furthermore, the LD50 and LC50 values are based upon a solitary dose and are taped in milligrams of pesticide per kilogram of body weight (mg/kg) of the guinea pig or partially per million (ppm).


The lower the LD50 or LC50 worth of a pesticide item, the higher its poisoning to people and pets.

An ounce or more of this material might be deadly to a 150-pound individual. An active component with a dermal LD50 of 1,000 mg/kg would be in Toxicity Category II with a WARNING signal word. An energetic ingredient might have a high LD50 positioning it in a Poisoning Classification II, III, or IV however likewise have destructive eye/skin effects that take priority and location it in Toxicity Classification I
