What is a potential health effect of long-term exposure to particulate matter?

• A. Improved lung function
• B. Decreased risk of heart disease
• C. Respiratory illnesses
• D. Enhanced cognitive abilities

Answer: (C)

Long-term exposure to particulate matter is known to have significant adverse health effects, particularly in relation to respiratory health. Particulate matter consists of tiny particles suspended in the air, which can penetrate deep into the lungs and even enter the bloodstream. This exposure can lead to various respiratory illnesses, such as asthma, chronic bronchitis, and even lung cancer. Studies have consistently shown that individuals exposed to high levels of particulate matter are at an increased risk of developing these conditions, highlighting the harmful impact of air pollution on respiratory health. In the context of the other options, improved lung function and a decreased risk of heart disease are not associated with long-term exposure to particulate matter; rather, such exposure tends to have opposing effects. Similarly, enhanced cognitive abilities are not linked to particulate matter exposure, as research suggests that air pollution, including particulate matter, may even contribute to cognitive decline. Thus, the risk of respiratory illnesses directly correlates with the detrimental effects of long-term exposure to particulate matter.
