Particulate matter is a health risk
The finer the particles, the greater the health risk that they pose. It is important to note that the chemical composition of fine dust is not the only decisive factor in assessing the health risk, because even chemically non-toxic particles can also penetrate deep into the respiratory tract, and some particles may even reach the pulmonary alveoli.
Fine dust is believed to be cancer-causing, even without having an immediate toxic effect. A great load is placed on the bronchial area and lungs, if the respiratory tracts or the pulmonary alveoli are blocked by fine dust particles. Depending on the application, ultra-fine particles can impact the health of employees and even the product quality.
