Pollen vs Staub
dust
'der Staub' and 'der Pollen' are both very fine particles that can be in the air or lie on surfaces. But 'Staub' is more general: it can consist of earth, dirt, or many other dry materials. 'Pollen' comes from plants and is flower dust. People often talk about pollen especially in spring because it can trigger allergies. Learners may confuse the words because pollen can look like dust. If the particles come from flowers, trees, or grasses, 'Pollen' is more precise. Otherwise, you usually say 'Staub'.
