Additionally, the LD50 and LC50 values are based on a single dosage and are taped in milligrams of pesticide per kilogram of body weight (mg/kg) of the test pet or partly per million (ppm).


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

The chronic poisoning of a pesticide is determined by subjecting test pets to long-term direct exposure to the active ingredient.
