Which type of pollution includes POPs?

• A. Physical pollution
• B. Chemical pollution
• C. Biological pollution
• D. Thermal pollution

Answer: (B)

POPs are chemical substances that persist in the environment, resist breakdown, and bioaccumulate through food webs. Because pollution classifications focus on what is released, persistent organic pollutants are categorized as chemical pollution. They aren’t physical debris, biological agents like pathogens, or heat-related discharges that alter temperature. Examples include DDT, PCBs, and dioxins, whose chemical stability and tendency to accumulate in organisms lead to long-range transport and ecological harm.
