Sleep and indoor air quality: an exploratory polysomnographic evaluation of pot...

This exploratory pilot study examines the potential impact of indoor environmental exposures on sleep quality, with a particular focus on a comprehensive characterization of indoor air quality (IAQ) parameters and their association with sleep architecture assessed through polysomnography. The study was conducted during the cold seasons of 2016 and 2017 with a small sample of 10 subjects from the urban area of L...

Strawberry plant as a biomonitor of trace metal air pollution: a citizen scienc...

A biomonitoring study of air pollution was developed in an urban-industrial area (Seixal, Portugal) using leaves of strawberry plants (Fragaria × ananassa Duchesne ex Rozier) as biomonitors to identify the main sources and hotspots of air pollution in the study area. The distribution of exposed strawberry plants in the area was based on a citizen science approach, where residents were invited to have the plants...

Microplastic contamination of lettuces grown in urban vegetable gardens in Lisb...

Urban vegetable gardens are very often a feature of cities that want to offer their citizens a more sustainable lifestyle by producing their own food products. However, cities can have significant pollution levels (or pollution hotspots) due to specific sources of pollution, such as traffic. Among the various pollutants, microplastics (MPs) are emerging as a consensual concern due to the awareness of the enviro...

Short-term exposure to PM10 and black carbon in residential microenvironments i...

Several studies have evaluated PM concentrations in single specific microenvironments as a measure of exposure in the entire house. In this study, PM10 was monitored at the same time in three microenvironments (bedroom, living room, and kitchen) from three dwellings located in a small inland town of the Iberian Peninsula to assess whether exposure varies significantly between them. Real-time optical instruments...

Source apportionment of PM2.5 before and after COVID-19 lockdown in an urban-in...

The lockdowns held due to the COVID-19 pandemic conducted to changes in air quality. This study aimed to understand the variability of PM2.5 levels and composition in an urban-industrial area of the Lisbon Metropolitan Area and to identify the contribution of the different sources. The composition of PM2.5 was assessed for 24 elements (by PIXE), secondary inorganic ions and black carbon. The PM2.5 mean concentr...

Citizens’ perception on air quality in Portugal: how concern motivates awareness

This study aimed to understand the knowledge of Portuguese citizens about air quality and the extent to which the concerns about specific environmental problems can motivate their acquaintance of information. Moreover, this study also allowed to understand which information about air quality needs further dissemination to provide the citizens with all the available tools and the correct knowledge. For this, a n...

Oxidative potential of fine aerosols from a Portuguese urban-industrial area: p...

Spatial distribution of air pollution, hotspots and sources in an urban-industr...

This study aimed to understand the influence of industries (including steelworks, lime factories, and industry of metal waste management and treatment) on the air quality of the urban- industrial area of Seixal (Portugal), where the local population has often expressed concerns regarding the air quality. The adopted strategy was based on biomonitoring of air pollution using transplanted lichens distributed over...

The pathway towards low carbon schools: criteria, targets and solutions

This book presents the research work carried out in the European project ClimACT within the Interreg SUDOE Programme. The book collects the main research activities and findings to promote a low-carbon economy in schools, where we developed a special collaboration and awareness between authorities, researchers, companies, non-governmental organizations (NGOs), and school communities on the road to sustainable s...
