Additionally, the LD50 and LC50 values are based upon a single dosage and are taped in milligrams of chemical per kilo of body weight (mg/kg) of the guinea pig or partially per million (ppm).


The lower the LD50 or LC50 worth of a chemical product, the better its poisoning to people and animals.

The chronic poisoning of a chemical is determined by subjecting guinea pig to lasting exposure to the active component.
