How does the concept of "likelihood of exposure" relate to pesticide hazard?

The concept of "likelihood of exposure" is crucial in understanding pesticide hazard because it directly impacts the risk assessment process. Risk assessment involves evaluating both the toxicity of the pesticide and the likelihood that individuals or the environment will come into contact with that pesticide. Assessing the likelihood of exposure helps to identify potential hazards associated with pesticide use and guides safety measures necessary to mitigate those hazards.

In this context, even a highly toxic pesticide could pose a low risk if the likelihood of exposure is minimal. Conversely, a pesticide with lower toxicity might present a greater risk if it is frequently used in a manner that increases the likelihood of exposure. Therefore, the overall risk posed by a pesticide is a function of both its inherent toxicity and the likelihood that people, animals, or ecosystems will come into contact with it. This consideration is essential for the development of effective regulations and safety practices concerning pesticide use.
