“…multi-pollutant assessment to thoroughly characterize IAQ in schools, which would improve understanding of the children's exposure to indoor air pollutants and the most effective means to reduce these exposures. Such studies have also been useful in terms of developing strategies (such as source control) for preventing adverse health consequences for children in schools [41,42].…”

“…These symptoms arise associated with the residence time of an individual inside the building, but no pathology or effect can be identified. Symptoms such as headache; dizziness; nausea; apathy; somnolence; tiredness and/or weakness; among others, depend on the concentration and exposure to short or long term to a given pollutant (Marques, 2013), (Brickus, & Neto, 1999); (Madureira et al, 2015). The IAQ is directly related to the ventilation conditions in buildings.…”

. Indoor air quality in gyms -a case study in the county of Coimbra. Millenium, 2(2),[111][112][113][114][115][116][117][118][119][120] m 1 112 RESUMO Introdução: o aparecimento da qualidade do ar interior (IAQ) como ciência aparece nos anos 70 devido à crise energética com a consequente construção de prédios particulares. Esta visão só ganhou alívio mundial devido à descoberta de que uma diminuição nas taxas de troca de ar neste tipo de edifícios foi a principal causa de aumento da concentração de poluentes no ar interior. Métodos: O presente estudo caracteriza-se por ser de coorte de nível II, observacional e transversal. A amostra foi constituída por 3 ginásios de Coimbra e por 7 trabalhadores /. Para atingir esse objetivo, houve uma avaliação analítica dos parâmetros físicos e químicos e preenchimento de questionários pelos trabalhadores. Resultados: Em relação aos resultados obtidos dos parâmetros avaliados, é possível concluir que os PM 10 (Diâmetro de Partículas de 10 mg / m3), os VOCs (Compostos Orgânicos Voláteis) e a Umidade Relativa apresentaram valores de risco relativos à saúde dos trabalhadores. Conclusões: Os dados coletados, mostram a relevância dos estudos sobre a qualidade do ar para garantir no futuro ações preventivas de uma melhor qualidade de vida para todos. Palavras-chave:Qualidade do Ar Interior; Parâmetros ambientais físico-químicos; Saúde pública. ABSTRACT Introduction:The appearance of the Indoor Air Quality (IAQ) as a Science appear in the 70's due to the energy crisis with consequent construction of private buildings. This vision only gained worldwide relief because of the discovery that a decrease in rates of air exchange in this type of buildings was the main cause for air increased pollutant concentration in the indoor air. Objetives: To evaluate the IAQ regarding the applicable legislation in gyms. Methods: The present study is characterized by being of level II, observational and cross-sectional cohort. The sample consisted of 3 gyms Coimbra and by 7 workers/. In order to achieve this objective, there was an analytical assessment of both physical and chemical parameters and filling questionnaires by the workers. Results: Regarding the obtained results of the evaluated parameters, it is possible to conclude that the PM 10 (Particulate Matter diameter of 10 mg/m

“…In terms of health effects, PM as well as VOCs pollutants could affect the respiratory system, which is the principal route of entry for air pollutants that are further exacerbated in the children or elderly [11,30]. Even in low concentrations, the presence of PM and VOCs indoors can lead to significant impacts on the respiratory health of children or susceptible individuals, such as those with low lung function, asthma and bronchitis [12].…”

a b s t r a c tChildren are by far more susceptible to the negative effects of air pollutants than adults. Building-level characteristics are structural factors largely beyond the control of those who live in them. Yet, there are gaps in understanding of the relationship of school building characteristics and/or occupant behaviour and indoor air parameters with implications for health and well-being.The aims of the study were to investigate the potential sources of CO 2 , PM 10 and volatile organic compound (VOCs) in naturally ventilated primary schools and to assess the potential health hazards of PM 10 on schoolchildren.CO 2 and PM 10 levels were determined in seventy three classrooms located in Porto city over a period of 8 h using low-drift NDIR sensors and light-scattering laser photometers, respectively. The VOCs samples were collected over 5-days in Tenax TA tubes and then analysed by gas chromatography coupled mass spectrometry.Principal component analysis revealed the influence of activities or building features as major sources of indoor CO 2 , PM 10 and VOCs associated to the reduced airing of the classrooms which underlines the influence of indoor sources, occupant behaviour and maintenance/cleaning activities in schools and the high density of occupants.The hazard quotient calculated based on the formula suggested by the United States Environmental Protection Agency is higher than the acceptable level of 1; being for children almost twelve times higher than the safe level. This indicates that the inhalation exposure to PM 10 by children and adults occupying the school environment is not negligible.
