  2. Exposure to Air Pollutants • Chronic • Acute • Air Pollution Episode – short-term increase concentrations • Dependent on local conditions • Epidemiological studies • Statistical relationship between environmental factors and human disease • Population susceptibility or change • Latency period • Lung cancer – up to 30 years • Toxicological studies • Determine effects of toxic substances • Pollutant interactions Smog Episode in New York City, 1963 National Archives, photo by Chester Higgins

  3. Psychological and toxic effects of air pollution can lead to psychiatric symptoms, including anxiety and changes in mood, cognition, and behavior.

  4. Manifestations are often insidious or delayed, but they can provide a more sensitive indicator of toxic effects than cancer rates or mortality data. Numerous toxic pollutants interfere with the development and adult functioning of the nervous system. Other medical effects of air pollution, such as asthma, can indirectly affect psychological health.

  5. 6 Perceived environmental noise and low air quality have been linked to mental health outcomes in adults such as depression.17 Epidemiological studies have shown that living in areas with elevated concentration of air pollution is linked with decreased cognitive function,18–23 lower neurobehavioural testing scores in children,24 a decline in neuropsychological development in the first 4 years of life25 and elevated risk of autism spectrum disorders.

  6. long-term exposure to ambient fine airborne particulate matter (<2.5 μm (PM2.5)) affects cognition, affective responses, hippocampal inflammatory cytokines and neuronal morphology

  7. Prenatal Exposure to Air Pollution, Maternal Psychological Distress, and Child Behavior Significant interactions between maternal demoralization and PAH exposure (high versus low) were identified for symptoms of anxious/depressed, withdrawn/depressed, social problems, aggressive behavior, internalizing problems, and externalizing problems.

  8. Increased levels of some air pollutants are accompanied by an increase in psychiatric admissions and emergency calls and, in some studies, by changes in behavior and a reduction in psychological well-being.
