What does the term “toxicity” refer to in relation to pesticides?

The term "toxicity" refers to the measure of potential harm a substance can cause to organisms, including humans, when they are exposed to it. In the context of pesticides, toxicity indicates how harmful a particular pesticide can be, based on factors such as its chemical composition, the dose, and the exposure route. Understanding toxicity is crucial for risk assessment and regulatory purposes, as it helps determine safe application practices and the potential impact on non-target species and the environment.

The focus on potential harm underscores the importance of evaluating the risks associated with pesticide use, informing decisions about usage guidelines, and ensuring consumer and environmental safety. This aspect of toxicity is fundamental for environmental health specialists in assessing the safety and efficacy of pesticide products.
