Abstract:

All pesticides must be toxic, or poisonous, to be effective against the pests they are intended to control. Because pesticides are toxic, they are potentially hazardous to humans, animals, other organisms and the environment. Therefore, people who use pesticides or regularly come in contact with them must understand the relative toxicity and potential health effects of the products they use. The toxicity of a pesticide is its capacity or ability to cause injury or illness. The toxicity of a particular pesticide is determined by subjecting test animals to varying dosages of the active ingredient (a.i.) and each of its formulated products. The active ingredient is the chemical component in the pesticide product that controls the pest. The two types of toxicity are acute and chronic. Acute toxicity of a pesticide refers to the chemical’s ability to cause injury to a person or animal from a single exposure, generally of short duration. The four routes of exposure are dermal (Skin), inhalation (Lungs), oral (Mouth) and eyes. Acute toxicity is determined by examining the dermal toxicity, inhalation toxicity and oral toxicity in test animals. In addition, eye and skin irritation are also examined. Read more...
