At the beginning of the year, the World Health Organization (WHO) announced that the Middle East ranks among the regions with the worst air quality. There is a common misconception that desert dust ...

Dirty windows can harbor potentially harmful pollutants under protective films of fatty acids from cooking emissions -- and these can hang around over long periods of ...

The 2019/20 wildfires in Australia transported more smoke into the atmosphere than observed ever before anywhere in the world. In the so-called Black Summer, three times as many particles reached ...
