Nutritional quality of foods consumed by the Portuguese population according to...
Santos, Mariana; Matias, Filipa; Fontes, Tânia; Bento, Ana Cristina; Pires, Maria João; Nascimento, Ana; Santiago, Susana; Castanheira, IsabelIn the last few years, public health authorities have shown interest in introducing front-of-pack labelling (FOPL), as one of the main policies to combat diet-related non-communicable diseases (NCDs). Nutri-Score is a FOPL that categorizes a food product into five categories according to its nutritional value. This study aimed to investigate the ability of Nutri-Score to discriminate the nutritional quality of ...
Vigilância da qualidade nutricional de refeições hospitalares, entre 2017 e 2019
Bento, Ana Cristina; Matias, Filipa; Fontes, Tânia; Pires, Maria João; Nascimento, Ana Cláudia; Santiago, Susana; Santos, Mariana; Castanheira, IsabelA alimentação em meio hospitalar tem vindo a ser objeto de debate junto dos profissionais de saúde, dado o papel determinante que desempenha no tratamento e recuperação do doente. O estudo teve como objetivo avaliar a qualidade nutricional de refeições hospitalares recolhidas entre 2017 e 2019. Foram analisadas laboratorialmente 32 refeições completas constituídas por prato de carne (53,1 %), prato de pescado (...
Caracterização do perfil de ácidos gordos de alimentos consumidos pela populaçã...
Gomes, Leonor; Fontes, Tânia; Vilarinho, Fernanda; Tavares, Nelson; Santos, Mariana; Castanheira, IsabelIntrodução: De acordo com o estudo Global Burden of Disease (GBD) realizado em 2017, os hábitos alimentares inadequados dos portugueses foram o terceiro fator de risco que mais contribuiu para a perda de anos de vida saudável. Na última década, diversos estudos epidemiológicos têm evidenciado uma relação entre a saúde e o consumo de certos tipos de gordura, nomeadamente pela ingestão de alguns ácidos gordos esp...
Resultados do Projeto MISAGE: Estratégias de redução de acrilamida e produtos d...
Jesus, Susana; Delgado, Inês; Coelho, Inês; Mota, Carla; Fontes, Tânia; Castanheira, IsabelEste projeto tem como objetivo o desenvolvimento de diferentes combinações de extratos e subprodutos nacionais de forma a mitigar a concentração de acrilamida em produtos de panificação. A IARC classifica a acrilamida como uma substância cancerígena para animais e possivelmente para humanos. Posteriormente, foi classificada como uma substância neurotóxica, sendo que afeta o sistema nervoso periférico e em casos...
Exposure to BTEX in buses: the influence of vehicle fuel type
Fontes, Tânia; Manso, M. Conceição; Prata, Joana C; Carvalho, Márcia; Silva, Cláudia; Barros, NelsonDiesel-fueled buses have been replaced by Compressed Natural Gas (CNG) to minimize the high level of emissions in urban areas. However, differences in indoor exposure levels to Benzene, Toluene, Ethylbenzene and Xylene (BTEX) in those vehicles have not been investigated so far. The primary aim of this study was to determine if passengers are exposed to different BTEX levels when using buses powered by CNG or by...
Environmental and biological monitoring of benzene, toluene, ethylbenzene and x...
Barros, Nelson; Carvalho, Márcia; Silva, Cláudia; Fontes, Tânia; Prata, Joana C.; Sousa, André; Manso, M. ConceiçãoThe volatile organic compounds benzene, toluene, ethylbenzene, and xylene (BTEX) are emitted into the atmosphere at gas stations (GS) leading to chronic exposure of nearby residents, which raises public health concerns. This study aimes at determining the contribution of GS emissions to BTEX exposure in nearby residents. Three Control and Exposed areas to BTEX emissions from GS were defined in a medium-sized Eu...
Improving air quality in Lisbon: modelling emission abatement scenarios
Monjardino, J.; Barros, Nelson; Ferreira, F.; Tente, H.; Fontes, Tânia; Pereira, P.; Manso, M. ConceiçãoLisbon is one of the European cities where NO2 and PM10 legal limit values are still exceeded, leading to an Air Quality Plan applicable up to 2020. The developed work combined a detailed emission inventory, monitoring data, and modelling in order to assess if the proposed emission abatement scenarios, focused on the road transport sector, were able to tackle exceedances. A maximum decrease of 14% for PM10 conc...
A proposed methodology for impact assessment of air quality trafficrelated meas...
Fontes, Tânia; Li, Peilin; Barros, Nelson; Zhao, PengjunAir quality traffic-related measures have been implemented worldwide to control the pollution levels of urban areas. Although some of those measures are claiming environmental improvements, few studies have checked their real impact. In fact, quantitative estimates are often focused on reducing emissions, rather than on evaluating the actual measures’ effect on air quality. Even when air quality studies are con...
Exploring multiple eco-routing guidance strategies in a commuting corridor
Bandeira, Jorge M.; Fernandes, Paulo; Fontes, Tânia; Pereira, Sérgio Ramos; Khattak, Asad J.; Coelho, Margarida C.The introduction of eco-routing systems has been suggested as a promising strategy to reduce carbon dioxide emissions and criteria pollutants. The objective of this study is to scrutinize the impacts of an eco-routing guidance system on emissions through the use of a case study in a commuting corridor. This research aims at assessing the potential environmental benefits in terms of different pollutant emissions...
Trends of PM2.5 concentrations in China: a long term approach
Fontes, Tânia; Li, Peilin; Barros, Nelson; Zhao, PengjunThe fast economic growth of China along the last two decades has created a strong impact on the environment. The occurrence of heavy haze pollution days is the most visible effect. Although many researchers have studied such problem, a high number of spatio-temporal limitations in the recent studies were identified. From our best knowledge the long trends of PM2.5 concentrations were not fully investigated in C...
