Final answer:
The unintended airborne movement of pesticides is called drift, a form of non-point source air pollution affecting non-target areas. The "Grasshopper Effect" describes the long-range atmospheric movement of pollutants like POPs. Run-off of fertilizers into water bodies is considered nonpoint source pollution, significantly impacting water quality.
Step-by-step explanation:
The airborne movement of pesticides to non-target areas can be described as drift. This is the process whereby pesticide particles are carried by wind to areas that are not intended for their application, potentially causing harm to the environment and non-target species. Drift is a form of air pollution and a major concern in agricultural practices. To prevent environmental damage from drift and ensure the safety of ecosystems, it's important to apply pesticides carefully and in suitable weather conditions to minimize off-target movement.
The "Grasshopper Effect" refers to the long-range movement of certain types of pollutants, such as persistent organic pollutants (POPs), across different regions of the Earth. These pollutants can enter the atmosphere and be transported by wind currents, sometimes for vast distances, before they settle back down to land or water surfaces.
When fertilizers from residential lawns and agricultural fields enter water bodies through surface run-off or movement through groundwater, the resulting pollution is considered nonpoint source pollution. This is a key issue for water quality, as it contributes to the leading causes of water pollution in places like the U.S., affecting aquatic ecosystems and human health.
