An increasing number of studies examined the potential effects of ambient particulate matter (PM: PM2.5 and PM10—PMs with diameters not greater than 2.5 and 10 μm, respectively) pollution on the risk of depression and suicide; however, the results have been inconclusive. This study aimed to determine the overall relationship between PM exposure and depression/suicide based on current evidence. We conducted a systematic review and meta-analysis of current available studies. Thirty articles (20…

Suicide and Associations with Air Pollution and Ambient Temperature: A Systematic Review and Meta-Analysis

Suicide risks associated with air pollution did not significantly differ by income level, national suicide rates, or average exposure levels, and research gaps were found for interactions between air pollution and temperature on suicide risks.

Relationship between fine particulate air pollution and hospital admissions for depression: a case-crossover study in Taipei

The relationship between ambient outdoor PM2.5 exposure and rates of hospitalization for depression appeared to be temperature dependent in Taipei and it was found that on warm days, the association continued to be significant after including one of the following pollutants.

Exposure to indoor air pollution from solid fuel and its effect on depression: a systematic review and meta-analysis

A growing body of research has investigated the relationship between indoor air pollution from solid fuel and depression risk. Our study aimed to elucidate the relationship between indoor air

The Effect of Meteorological, Pollution, and Geographic Exposures on Death by Suicide: A Scoping Review

Strong evidence supports that exposure to sunlight, temperature, air pollution, pesticides, and high altitude increases suicide risk, although effect sizes range from very small to small.

Examining air pollution (PM10), mental health and well-being in a representative German sample

Investigating the physical environmental factor, air pollution, measured by particulate matter of particles with an aerodynamic diameter smaller than 10 µm and effects on determinants of mental health and well-being shows that higher life satisfaction, more self-esteem and higher stress resilience are predicted by less air pollution (PM10).

Air Pollution and Suicide in Mexico City: A Time Series Analysis, 2000–2016

No evidence of a statistical association is found between air quality and daily suicides registered in Mexico City between 2000 and 2016, and the effects of the pollutants were very close to the null value in the majority of the models, and no accumulative effects were identified.

Air Pollution (Particulate Matter) Exposure and Associations with Depression, Anxiety, Bipolar, Psychosis and Suicide Risk: A Systematic Review and Meta-Analysis

The hypothesis of an association between long-term PM2.5 exposure and depression is supported and the limited literature and methodological challenges in this field, including heterogeneous outcome definitions, exposure assessment, and residual confounding, suggest further high-quality studies are warranted to investigate potentially causal associations between air pollution and poor mental health.

Long-Term Particulate Matter Exposure and Onset of Depression in Middle-Aged Men and Women

A positive association between long-term exposure to outdoor PM10 air pollution and the developing depression is found; however, this large cohort study had a much shorter follow-up for subjects’ exposure to PM2.5 air pollution.

Association of Ambient Air Pollution with Depressive and Anxiety Symptoms in Older Adults: Results from the NSHAP Study

PM2.5 was associated with depressive and anxiety symptoms, with associations the strongest among individuals with lower SES or among those with certain health-related characteristics.

Long-Term Fine Particulate Matter Exposure and Major Depressive Disorder in a Community-Based Urban Cohort

Long-term PM2.5 exposure increased the risk of MDD among the general population and was greater in participants with underlying chronic diseases than in participants without these diseases.

Acute air pollution exposure and risk of suicide completion.

Findings of positive associations between air pollution and suicide appear to be consistent across study locations with vastly different meteorological, geographical, and cultural characteristics.
