McGraw-Hill Connect Biology – Air Quality SmartBook Practice Test

Living in a city with significant air pollution is associated with a lower life expectancy due to the adverse health effects caused by pollutants in the air. Air pollution contains harmful substances, such as particulate matter, nitrogen oxides, sulfur dioxide, and volatile organic compounds, which have been linked to various health issues, including respiratory diseases, cardiovascular problems, and even cancer.

Studies consistently demonstrate that populations exposed to high levels of air pollution experience higher rates of these health issues, contributing to increased mortality rates. As pollutants infiltrate the lungs and enter the bloodstream, they can lead to chronic health conditions that reduce overall life expectancy. Thus, the statistical evidence supports the conclusion that living in areas with high air pollution correlates with a reduced lifespan.
