Study Links Exposure to Air Pollution With Increased Risk of Suicide and Suicidal Thoughts

A meta-analysis published in the Journal of Epidemiology and Community Health linked short- and long-term exposure to particulate matter and nitrogen dioxide with heightened suicide risks.

Researchers from Queen's University Belfast reviewed 29 studies, concluding that environmental pollutants can induce neurological effects such as chronic inflammation and impaired brain function.

Independent experts noted that while the associations are statistically significant, effect sizes were relatively small and require further research accounting for confounding meteorological variables.
