Furthermore, the LD50 and LC50 values are based on a single dosage and are recorded in milligrams of chemical per kilogram of body weight (mg/kg) of the guinea pig or in components per million (ppm).


The reduced the LD50 or LC50 value of a pesticide item, the greater its poisoning to humans and animals. Pesticides with a high LD50 are the least harmful to people if used according to the directions on the product tag. The persistent toxicity of a chemical is identified by subjecting test animals to lasting exposure to the active component.


The chronic toxicity of a chemical is harder than severe poisoning to determine through lab analysis. click this site Products are classified on the basis of their relative acute poisoning (their LD50 or LC50 values). Pesticides that are classified as extremely harmful (Poisoning Category I) on the basis of either oral, facial, or breathing toxicity should have the signal words threat and toxin printed in red with a head and crossbones sign plainly displayed on the front panel of the bundle tag.
