The solid particles of non-hygroscopic dust found in the atmosphere come from several sources, some of which are strictly natural and some artificial. The mineral dust resulting from disintegration of rocks provides a source of small particles. ... If the particles are small enough, they will settle slowly and so will remain in the air for a fairly long period. Pollen grains from plants are carried about by the wind, but the pollen supply is seasonal. 3, record 1, English, - pollen%20grain

Pollens. Les grains de pollen constituent des pneumallergènes puissants, susceptibles de provoquer chez l'être humain des réactions individuelles de gravité variable. [...] Le diamètre des grains de pollen oscille entre 10 et 50 microns suivant le végétal dont ils proviennent (herbes, arbres [...]). La plupart d'entre eux sont hygroscopiques et augmentent donc de poids avec l'humidité de l'atmosphère. 2, record 1, French, - grain%20de%20pollen
