The reduced the LD50 or LC50 worth of a chemical product, the greater its poisoning to human beings and animals. Chemicals with a high LD50 are the least poisonous to human beings if made use of according to the directions on the product label. The persistent toxicity of a chemical is established by subjecting examination pets to long-lasting direct exposure to the energetic component.


The persistent toxicity of a chemical is harder than intense poisoning to determine with lab evaluation.

As an example, an energetic component with a dermal LD50 of 1,000 mg/kg would certainly be in Poisoning Classification II with a WARNING signal word. Remember that an energetic component may have a high LD50 placing it in a Toxicity Category II, III, or IV but also have destructive eye/skin impacts that take top priority and place it in Poisoning Group I.


All chemical toxicity values, including the LD50, can be located on the item's Material Safety and security Information Sheet (MSDS) - pest control Washington DC.
