Severe episodic air pollution blankets entire cities and regions have a profound impact on humans their activities. We compiled daily fine particle (PM2.5) data from 100 in five continents, investigated the trends of number, frequency, duration episodes, compared these with baseline trend pollution. showed that factors contributing to events are complex; however, long-term measures abate emissions all anthropogenic sources at times is also most efficient way reduce occurrence severe events. In short term, accurate forecasting systems such based meteorological conditions favouring occurrence, together effective emergency mitigation sources, may lessen magnitude and/or duration. However, there no clear preventing caused by natural affected climate change, as wildfires desert dust outbreaks.
