How is Pesticide Risk calculated?

Pesticide risk is calculated by considering both the toxicity of the pesticide and the level of exposure. The correct approach involves multiplying the toxicity by the level of exposure. This method reflects the concept that risk increases with either higher toxicity or greater exposure. Essentially, if a pesticide is highly toxic, even a small level of exposure can pose significant risks. Conversely, if exposure levels are high, even a pesticide with lower toxicity might lead to a considerable risk. Therefore, the multiplication of these two factors gives a comprehensive assessment of the potential risk associated with pesticide use, which is crucial for ensuring safe application and protecting human health and the environment.
