Although it’ s difficult to estimate the percentage of time every individual spends indoors, it is a matter of fact that the incidence of PM on health is often overlooked. When we talk about indoor PM we do not only mean the particulate matter generated by indoor activities such as combustion, fumes or other substances of biological origin. Indoor particulate matter is also the result of the inward migration of external particulate matter, a migration that can occur in a variety of ways: from cracks in the building envelope to infiltration, from the type of filters and ventilation used to natural ventilation and consequently to the external environment around us. It is therefore essential that indoor PM exposure is regularly measured and controlled in order to avoid harmful health effects.
