In addition, the LD50 and LC50 worths are based on a single dosage and are taped in milligrams of chemical per kilo of body weight (mg/kg) of the guinea pig or in parts per million (ppm).

The reduced the LD50 or LC50 value of a pesticide item, the higher its poisoning to humans and pets. Pesticides with a high LD50 are the least harmful to humans if made use of according to the directions on the product label. The persistent toxicity of a pesticide is determined by subjecting guinea pig to lasting exposure to the active component.

The persistent poisoning of a chemical is more challenging than severe toxicity to identify with research laboratory evaluation. Products are classified on the basis of their loved one severe poisoning (their LD50 or LC50 worths). Chemicals that are categorized as very hazardous (Poisoning Classification I) on the basis of either dental, dermal, or breathing toxicity have to have the signal words risk and POISON published in red with a skull and crossbones symbol prominently showed on the front panel of the package label.
