Fine dust - generation

Fine dust is the smallest particle that is carried by the air. Depending on local conditions, this dust can come from natural or man-made sources. Natural sources are rock dust, fungal spores, pollen, sea salt, ash from volcanic eruptions or carbon compounds from bush and forest fires, which are caused by erosion. Man-made sources include, for example, agricultural and livestock erosion, factory fumes, wood heating, and open fireplaces. Fine dust can also arise in closed rooms, for example from tobacco smoke or from laser printers and copiers.

Health hazards due to fine dust pollution

Numerous studies have shown that fine dust pollution is a high health risk. Fine dust massively increases the risk of cancer as well as the risk of arteriosclerosis (hardening of the arteries) and diseases of the lungs. In addition, there is a high risk of heart attack due to fine dust. (vb)
