Additionally, the LD50 and LC50 values are based upon a single dose and are taped in milligrams of chemical per kilo of body weight (mg/kg) of the examination pet or partly per million (ppm).
The lower the LD50 or LC50 worth of a pesticide item, the greater its poisoning to humans and animals. Pesticides with a high LD50 are the least harmful to people if utilized according to the directions on the product label. The chronic toxicity of a pesticide is identified by subjecting guinea pig to lasting exposure to the active ingredient.
The persistent poisoning of a pesticide is harder than severe toxicity to identify through lab analysis. Products are categorized on the basis of their relative severe toxicity (their LD50 or LC50 worths).
