Particulate matter and health risk under a changing climate: assessment for Por...

Dias D.,; Tchepel O.,; Carvalho A.,; Miranda A.I.,; Borrego C.

In this work the potential impacts of climate-induced changes in air pollution levels and its impacts on population health was investigated. The IPCC scenario (SRES A2) was used to analyse the effects of climate on future PM10 concentrations over Portugal and their impact on short-term population exposure and mortality. The air quality modelling system has been applied with high spatial resolution looking on cl...


Contribution of residential wood combustion to PM10 levels in Portugal

Borrego, C.; Valente, J.; Carvalho, A.; Sá, E.; Lopes, M.; Miranda, A. I.

Wood is commonly used in residential combustion for heating purposes; however, it can be a major source of air pollutants, namely fine particles, volatile organic compounds and carbon monoxide. Since 2004, the PM10 daily limit value has been surpassed in Portugal, and the European Commission has stated that plans and programs must be designed in order to reduce these levels. In Portugal, 18% of PM10 emissions a...


Air quality assessment for Portugal

Monteiro, A.; Miranda, A. I.; Borrego, C.; Vautard, R.

According to the Air Quality Framework Directive, air pollutant concentration levels have to be assessed and reported annually by each European Union member state, taking into consideration European air quality standards. Plans and programmes should be implemented in zones and agglomerations where pollutant concentrations exceed the limit and target values. The main objective of this study is to perform a long-...


Frequency analysis of air quality time series for traffic related pollutants

Tchepel, O.; Borrego, C.

In the present work, annual time series of traffic related pollutants (CO and PM10) were considered for frequency analysis (Fourier series) with the aim to understand the underlying physical processes and the influence of emission sources on the variability of the air pollutant concentrations. Several urban traffic and suburban background air quality stations located in Porto metropolitan area (Portugal) were a...


Medição do Óxido Nítrico no Ar Exalado: Utilização na Avaliação de Crianças com...

Martins, P; Caires, I; Rosado-Pinto, J; Lopes Mata, P; Torres, S; Valente, J; Borrego, C; Neuparth, N

Encontram -se publicados múltiplos trabalhos sobre o papel das determinações do óxido nítrico no ar exalado (FENO) no âmbito do estudo da inflamação brônquica que nos permitem afirmar que se trata duma medição simples, não invasiva e de grande utilidade na avaliação do doente asmático.No decurso de um estudo prospectivo sobre o impacto da poluição do ar sobre a saúde da população na cidade de Viseu (Projecto Sa...
