PESTICIDE TOXICITY LEVELS AND EXPOSURE ROUTES FROM COLLIER PEST CONTROL NAPLES FORT MYERS FLORIDA

PESTICIDE TOXICITY LEVELS AND EXPOSURE ROUTES

1. Insecticide safety is the responsibility of everyone in the pesticide industry.  Applicators must use their knowledge of insecticide active ingredients and formulations to select the best products for the situation.
2. In order to be effective, insecticides must be toxic against the target pest.  Toxicity is the inherent ability of a chemical to constantly cause injury.
3. Unlike toxicity, which is constant, the hazard associated with insecticide use may vary depending on circumstances of its use.  Hazard refers to the potential for injury or danger of poisoning when an insecticide is used.  Hazard is the function of toxicity and the potential for exposure (hazard=toxicity x exposure).
4. With acute toxicity from a one-time exposure to relatively large amounts of an insecticide and generally seen within a few minutes of hours.  The acute toxicity for a particular insecticide is constant and is expressed as lethal dose or lethal concentration.
5. The term LD50 is the lethal dose, amount of insecticide, which kills 50% of test animals when eaten or absorbed through the skin.  It is usually expressed as milligrams of toxicant per kilograms of body weight.
6. The lower the LD50 the higher or more toxic the insecticide is to mammals.  This means it takes less insecticide to kill the 50% of the test animals
7. The ways in which an insecticide enters the body are referred to as the routes of exposure.  These routes may be through the skin (dermal), through the lungs and respiratory system (respiratory) or through the mouth (oral). 
8. Dermal exposure is the most significant route of exposure for pest management professionals.  Studies have shown that approximately 90% of all exposure to insecticides occurs as the result of skin contact.
9. Respiratory exposure generally account for less than 1% of the total exposure to insecticide applicators.  But, because the absorptive air sacs of the lungs have an enormous surface area for exposure, this route may contribute as much as 25% of the absorbed dose.
10. Oral exposure to insecticides can occur in various ways.  It can splash into the mouth, it can be ingested if you eat, drink, or smoke during or after an application.  Contaminated food handling or storage when treated will cause oral exposure.
