Furthermore, the LD50 and LC50 worths are based upon a solitary dose and are tape-recorded in milligrams of chemical per kilogram of body weight (mg/kg) of the test pet or in parts per million (ppm).


The reduced the LD50 or LC50 worth of a pesticide item, the better its poisoning to human beings and animals.

Maintain in mind that an active component may have a high LD50 positioning it in a Poisoning Classification II, III, or IV yet additionally have corrosive eye/skin impacts that take top priority and location it in Poisoning Classification I.


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