What does 'cumulative exposure' refer to in the context of pesticide use?

Cumulative exposure in the context of pesticide use refers to the total amount of pesticide exposure that accumulates from multiple applications over a period of time. This concept is crucial when evaluating the potential effects of pesticides on both target organisms and non-target species, as exposure is not limited to a single application. Instead, it encompasses all instances where a pesticide is used, creating a comprehensive view of the total exposure someone might have to that pesticide.

Understanding cumulative exposure is essential for assessing potential risks to human health and the environment. It informs practices regarding safe handling, application rates, and timing to minimize harmful effects. By considering the overall exposure rather than individual applications, stakeholders can better ensure practices align with integrated pest management (IPM) principles, which aim for environmentally sensitive pest control.
