Ball and PAH

Caption: When airborne particles (green) form before pollutants known as PAHs (yellow) glob on, both the pollutants and particles dissipate quickly, as shown in the top row. But when the particles form in the presence of pollutants, which is what likely happens in nature, the long-lasting particles can take the pollutants for a long-distance ride (bottom).
