“…Ambient particulate matter (PM) is considered one of the leading environmental health risk factors, associated with several health impacts worldwide [1]. Among the important and variable parameters of PM that may be linked with health consequences of exposures is the particle size [2]. Ambient aerosols generally include particles with aerodynamic diameter between 0.01 µm and 100 µm.…”

Exposure to ultrafine particles (UFPs size < 100 nm) in life and work environments can contribute to adverse health effects also in terms of health burden of related diseases over time. The choice of parameters which better characterize UFPs is challenging, due to their physical-chemical properties and their variable size. It is also strictly related to the availability of different instrumental techniques. In the present study we focus on real time high frequency (1 Hz) UFPs particle size distribution (PSD) and their relationship with total particle number concentration (TPNC) and mean particle diameter (Davg) as a contribution characterizing by size the human exposure to UFPs in an indoor site of the University of Rome “Sapienza” (Italy). Further considerations about UFPs contribution to nucleation mode (NM) and accumulation mode (AM) have been highlighted, also in order to investigate the contribution of polycyclic aromatic hydrocarbons (PAHs) surface-adsorbed on indoor air particles (pPAHs). High indoor TPNC values were registered during the rush hours (early morning and mid/late afternoon) according to the outdoor influences originated from anthropogenic activities. AM mainly contribute to the indoor TPNC during working days showing high correlation with pPAHs. These findings may provide useful indications in terms of occupational exposure to UFPs since there are many evidences that indoor exposures to such pollutants may be associated with adverse health effects also in working environments.

“…In urban environments, car traffic is a major source of air pollution and noise, which are leading causes of non-communicable diseases (NCDs) and thus of premature adult death (WHO 2016). The majority of human exposures to urban air pollution occurs while being indoors, with a wide range of health consequences for inhabitants (Nazaroff 2018;Rodopoulou et al 2022). The infiltration of outdoor pollution into dwellings can cause allergies, a weakening of the immune system, cancer and several respiratory diseases (Turcu et al 2021;WHO 2018).…”

As the world's population grows in cities, urban dwellers spend a large amount of time inside their home, making housing health ever more important. Critical for residents' health, the interactions between indoor residential environments and outdoor environmental conditions (e.g. air pollution, noise, heat) are mediated by the controversial and evolving relationship between housing and the street. Currently, there is a lack of ways to integrate and explore synergies among the plurality of perspectives that have addressed the interactions between housing, street and health (HSH). This paper proposes a systemic research framework to address conceptually, spatially and temporally HSH interactions. With a focus on European cities, determinants of housing health are identified through six perspectives, comprising environmental health, domestic architecture, building technologies, socio-economic inequalities, housing prices and urban planning. Their interrelationships are organised in a causal loop diagram, which can be used to highlight gaps in research and data. Subsequently, the paper explores the research and practical applications of the resulting systemic understanding, taking the context of Geneva, Switzerland, as an example. In sum, this study illustrates ways to integrate systemic, transdisciplinary and spatiotemporal approaches essential to holistically address the complexity of HSH relationships.

“…Particulate matter emitted outdoors affects indoor air quality, as buildings do not provide complete protection from outdoor air. This impacts human health as people spend an average of 90% of their time inside (Nazaroff, 2018).…”
