Which of the following correctly links a negative health effect to an anthropogenic source of particulate matter?

Which of the following correctly links a negative health effect to an anthropogenic source of particulate matter?

• A. Increased crop yields from PM emissions
• B. No health effects
• C. High respiratory disease from power plant emissions
• D. Improved breathing in polluted areas

Answer: (C)

Particulate matter from human activities can harm health when inhaled. Emissions from power plants come from burning fossil fuels, releasing fine particles (PM2.5) into the air. These small particles can travel deep into the lungs, causing inflammation and leading to respiratory problems such as asthma and bronchitis, and they also raise the risk of cardiovascular issues. That direct link between a negative health outcome (respiratory disease) and an human-made source (power plant emissions) is why this option is the best fit. The other statements describe benefits or no effects, which conflict with the well-established health risks of particulate pollution.
