Which factor is NOT included in calculating pesticide hazard?

The correct answer highlights that environmental impact is not directly incorporated into the calculation of pesticide hazard. When evaluating pesticide hazards, the primary factors considered are toxicity, exposure, and concentration.

Toxicity refers to the inherent ability of a pesticide to cause illness or harm in organisms, including humans, based on its chemical composition and biological effects. This is a crucial element in hazard assessment as it determines the potential health impact of the pesticide if exposure occurs.

Exposure is the assessment of how much and how often organisms, including humans, come into contact with the pesticide. The level of exposure can significantly influence the degree of risk associated with a pesticide's use, as higher exposure increases the likelihood of adverse effects.

Concentration relates to the amount of pesticide present in a given volume or weight of an application site or environment. Higher concentrations could signify a greater potential for harm, as they may lead to increased toxicity effects.

While environmental impact is a significant consideration in the broader context of pest management and sustainability, it does not contribute to the direct calculation of pesticide hazard, which focuses primarily on the pesticide’s toxicity, exposure levels, and concentration in a specific context.
