“…Setúbal is a high-density urban region that coexists not only with heavy industry but also with protected natural areas (Sado Estuary and Arrábida, which belongs to the protected area Natura 2000 Network). The industrial area includes (1) paper, cement, pesticides, fertilizers, and chemical industries, which are responsible for the emission of large amounts of particles and chemical elements (Freitas et al, 2003;Farinha et al, 2009, Almeida et al, 2012a; (2) harbors, which emit significant amounts of dust fugitive emissions (Almeida et al, 2012b;Silva et al, 2012); and (3) heavy traffic associated with the transport of products and materials (Garcia et al, 2013). In the city of Setúbal, traffic is the main source of atmospheric pollution.…”

In recent years, the adverse health effects attributed to air pollution have been a focus of intense study. Exposure to pollutants such as airborne particulate matter (PM) and ozone (O3) has been associated with increases in morbidity and mortality due to respiratory and cardiovascular diseases. The aim of this study was to determine a correlation between particles (PM10, PM2.5) and O3 with hospital admissions in Setúbal, a densely populated Portuguese urban region that coexists with a heavy industrial area. A database with daily air quality and hospital admission data over 5 years (2005-2009) was assembled and associations were investigated by ordinary least squares linear regression. Results showed positive significant associations between PM10 and respiratory diseases for ages below 14 yr and above 64 yr, and between PM2.5 and respiratory diseases for ages above 64 yr.

“…Moreover, the region also exhibits high levels of pollution. Several studies have already shown that local activities have a significant impact on the air quality due to: (i) emissions of air pollutants originating in industrial processes [ 6 , 7 , 8 ], (ii) dust fugitive emissions from the harbors [ 9 , 10 ], and (iii) intense traffic of heavy duty vehicles [ 11 ].…”

Understanding air pollution in urban areas is crucial to identify mitigation actions that may improve air quality and, consequently, minimize human exposure to air pollutants and their impact. This study aimed to assess the temporal evolution of the air quality in the city of Setúbal (Portugal) during a time period of 10 years (2003–2012), by evaluating seasonal trends of air pollutants (PM10, PM2.5, O3, NO, NO2 and NOx) measured in nine monitoring stations. In order to identify emission sources of particulate matter, PM2.5 and PM2.5–10 were characterized in two different areas (urban traffic and industrial) in winter and summer and, afterwards, source apportionment was performed by means of Positive Matrix Factorization. Overall, the air quality has been improving over the years with a decreasing trend of air pollutant concentration, with the exception of O3. Despite this improvement, levels of PM10, O3 and nitrogen oxides still do not fully comply with the requirements of European legislation, as well as with the guideline values of the World Health Organization (WHO). The main anthropogenic sources contributing to local PM levels were traffic, industry and wood burning, which should be addressed by specific mitigation measures in order to minimize their impact on the local air quality.

“…The analysis of the chemical profile of the studied settled dust indicates a major contribution from the industrial area nearby, along with minor traffic influence. It is possible that the source of this settled dust event is not only the industrial processes conducted in the industrial area, but also due to fugitive emissions of raw materials, for instance [52,53].…”

This study aimed to identify possible sources of settled dust events that occurred in an urban area nearby an industrial park, which alarmed the local population. Settled dust was collected in January 2019 and its chemical characterization was assessed by micro-PIXE, focusing on a total of 29 elements. Comparison with chemical profiles of particulate matter from different types of environment was conducted, along with the assessment of crustal enrichment factors and Spearman correlations, allowing to understand which sources were contributing to this settled dust event. A nearby industrial area's influence was identified due to the contents of Fe, Cr and Mn, which are typical tracers of iron and steel industries.
