Which term describes a pesticide that is particularly hazardous to humans or the environment?

The term that describes a pesticide particularly hazardous to humans or the environment is "restricted-use pesticide" (RUP). RUPs are substances that, due to their toxicity, require special handling and application procedures because they pose a higher risk. This designation is made by regulatory authorities who evaluate the potential risks associated with these chemicals.

Restricted-use pesticides undergo a rigorous evaluation process, which assesses factors such as their impact on non-target organisms, potential for groundwater contamination, and effects on human health. Because of their hazardous nature, these pesticides can only be sold or used by certified individuals who have received specific training to handle and apply them safely. This requirement helps ensure that such potentially dangerous substances are used effectively and responsibly, minimizing risk to people and the environment.

In contrast, general-use pesticides and non-restricted pesticides are those considered to pose less risk and can be purchased and applied by the general public without special certification. Eco-friendly pesticides typically refer to products deemed safer for the environment, further distinguishing them from restricted-use pesticides that are considered more hazardous.
