- Sulphate injections are one of several "geoengineering" solutions to climate change being discussed by scientists. The data published in "Science" magazine suggests that this strategy would lead to a drastic thinning of the ozone layer.
- Aerosols act as sites for chemical reactions to take place (heterogeneous chemistry). The most significant of these reactions are those that lead to the destruction of stratospheric ozone.
- Aerosols are very small particles that are suspended in the atmosphere.
- 1000 times more nanoparticle pollution is created by the combustion of jet fuel in a jet engine than in a standard diesel car.
- About 5 billion people use airplanes as a means of transport every year worldwide.
- Global dimming is the gradual reduction in the amount of global direct irradiance at the Earth's surface.
- Aircraft engines are believed to be a key source of inorganic sulphate particles and SO2 due to the high sulphur content in jet fuel.
- A baggage handler inhales roughly 240 billion nanoparticles each day they work at Copenhagen Airport.
