Why the estimate is credible
The site first converts a PM2.5 pollutant AQI into an estimated concentration, then applies Berkeley Earth's rough population health-impact comparison.
The result is for risk communication—not particle mass, inhaled dose, cigarettes actually smoked, personal risk, or diagnosis.
