The term "contamination" in relation to pesticides specifically refers to the presence of an unwanted substance in or on a plant, animal, soil, water, air, or structure. This definition highlights the concern for environmental and human health, emphasizing that pesticides, while useful for pest control, can inadvertently introduce harmful chemicals into various ecosystems and components of the environment.

Understanding contamination is crucial for pesticide applicators because it underscores the importance of following proper application and safety protocols to prevent unintended exposure or adverse effects. It also relates to the regulatory standards that exist to minimize environmental impact and ensure that pesticides are applied in a manner that protects public health.

The other options do not accurately encapsulate the concept of contamination. For instance, the process of safely disposing of hazardous substances, although important, does not describe contamination itself. Similarly, cleaning equipment after pesticide application refers to maintenance practices rather than the presence of an unwanted substance. A measure of pesticide effectiveness is related to how well a pesticide performs its intended function, rather than the definition of contamination.
