Why is it important to assess the likelihood of exposure when evaluating pesticide hazards?

Assessing the likelihood of exposure when evaluating pesticide hazards is crucial because it allows for the identification of the potential for harm to human health or the environment. Understanding exposure levels helps to determine who or what may be affected by pesticide use and the extent of that impact. This assessment is fundamental in risk assessment processes, where the goal is to evaluate not just the toxicity of a substance but also how often and at what levels people, wildlife, or ecosystems might come into contact with it. The greater the likelihood of exposure, the more serious the potential health risks or environmental damage could be, necessitating appropriate management strategies to mitigate those risks. In this context, the focus is on protecting public health and the environment from the adverse effects associated with pesticides, making it essential to thoroughly assess exposure likelihood.
