This study assessed children's exposure to particulate matter (PM1, PM2.5, PM10), ultrafine particles (UFP), and black carbon (BC) in indoor and outdoor environments (schools, homes, and gymnasium) in Lisbon. PM2.5 exposure was higher during the cold season, likely due to increased outdoor pollution and poor ventilation. In schools, PM2.5 levels increased during class hours and cleaning activities, while in homes, peaks occurred during cooking and cleaning. Indoor concentrations often exceeded outdoor levels, highlighting the significant impact of indoor activities on daily exposure to air pollution.

Air pollution impacts children's health, with ultrafine particles (UFPs) posing significant risks. As part of the InChildHealth project, monitoring campaigns in elementary schools across seven European cities assessed indoor air quality and children's exposure. This study presents data from Athens, Lisbon, and Essex, where real-time UFP number concentration and size distribution were measured inside five classrooms per city using Partector 2 Pro. Concurrent outdoor monitoring was performed. Initial results showed strong indoor-outdoor correlations, with ventilation and indoor activities influencing UFP levels. Indoor and outdoor UFP size distributions were analyzed to investigate mechanisms and indoor activities associated with increased UFP levels.

Raising awareness among businesses and institutions on the topic of indoor air quality requires scientific data and analysis models of a dual nature: 1) epidemiological and 2) economic.
The work quantifies the reduction in time spent in good health due to indoor pollution an turns it into the economic impact in terms of external costs.
Considering all the costs over the whole Italy, the indoor air PM pollution in schools and hospitals ranged between 54-106 billion of € accounting up to 5% of the Italian Gross Domestic Product (GDP). Therefore, treating indoor air means drastically reducing these costs.

Climate change affects indoor air quality through changes in ambient temperatures and pollutant concentrations, indoor chemical reactions and occupant behavior. This work applied the IAQCC model to examine the long- and short-term indoor particle concentrations in a German residence under the SSP5-8.5 scenario by 2100. Results show that temperature rise leads to increased formation of secondary organic aerosols via the limonene ozone reaction. However, this increase is compensated by future decreases in outdoor PM2.5 levels. Ozone events and Sahara dust storms can significantly increase indoor particle concentrations. Preventive measures are needed to reduce indoor air pollution risks.
