Which term describes the properties associated with persistence and resistance to environmental degradation typical of certain pesticides?

• A. Acute properties
• B. Bioavailability
• C. Foreign characteristics
• D. Volatility

Answer: (C)

Pesticides that persist in the environment do so because they have attributes that resist natural degradation and attenuation. These enduring traits are described as foreign characteristics—the properties that are not readily broken down by natural processes and thus keep the compound lingering in soil, water, and air. This explains long residence times and the potential for accumulation. In contrast, acute properties refer to short-term toxicity, bioavailability describes how much of the substance can be absorbed by organisms, and volatility describes how readily the substance vaporizes.
