McGraw-Hill Connect Biology – Air Quality SmartBook Practice Test

Poor air quality has been associated with various negative outcomes for mental health, making the link to increased stress, depression, and cognitive impairments significant. Scientific studies have shown that exposure to air pollutants, such as particulate matter and volatile organic compounds, can lead to inflammation in the brain and disrupt neurotransmitter systems, which are crucial for maintaining emotional and cognitive functions.

Furthermore, poor air quality can exacerbate anxiety and mood disorders, as the body’s stress response is activated by environmental stressors. Individuals living in areas with high levels of air pollution often report higher levels of psychological distress, which underscores the connection between the environment and mental health. Therefore, it is clear that the impact of air quality on mental health is a critical area of ongoing research and concern.
