The high exposure to particulate material can have negative effects on the health of people, prolonged exposure especially to particles of small sizes that can enter the depths of our respiratory system represent a high risk of contracting a disease in the medium or long term. Although the reference method to determine the exposure to particulate material is made by gravimetric sampling, in recent years technologies have been developed that allow the concentration of particulate material to be obtained immediately and in real time. With this instrumentation it is possible to obtain immediate results.
