Structural Pest Control Applicator Practice Exam

Pesticide residues can build up in the bodies of animals, including humans. What is the true statement?

1. True

2. False

3. Only in plants

4. Only in water

The correct answer is: True

Pesticide residues can accumulate in the bodies of animals, including humans, which is a significant concern in environmental health and safety. When pesticides are applied, they can enter the food chain, subsequently affecting various organisms. Animals may ingest pesticides directly through contaminated food or water or indirectly through consumption of other organisms that have accumulated pesticide residues. This accumulation happens due to a process known as bioaccumulation, where individuals, over time, absorb more of a substance than they eliminate. Given that humans and other animals are at the top of many food chains, they can be exposed to higher concentrations of these residues, leading to potential health risks. Understanding this process is essential for pest control applicators, as it emphasizes the importance of responsible pesticide use and the need to adhere to guidelines that minimize human and environmental exposure. The incorrect options suggest that residues are limited to plants or water, which overlooks the broader implications of pesticide exposure across various ecosystems and organisms.
