Here we apply a statistical model that leverages random increases in particulate pollution (PM<sub>2.5<\/sub>) due to meteorological conditions to comprehensive data on suicide rates across Chinese counties.

This effect occurs without delay, consistent with neurobiological evidence that PM<sub>2.5<\/sub>\u00a0influences emotional regulation and impulsive\u2013aggressive behaviour. Effects are sex and age specific; women over 65 exhibit significantly higher vulnerability. We estimate that PM<sub>2.5<\/sub>\u00a0reductions under China\u2019s Air Pollution Action Plan prevented 13,000\u201379,000 (95% confidence interval) suicides over 2013\u20132017, accounting for\u00a0<span class=\"stix\">\u223c<\/span>10% of this period\u2019s observed suicide rate decline.
