Effect of individual's characteristics on volatile organic compoounds profile a...
Slezakova, Klara; Cavaleiro-Rufo, J.; Esteves, F.; Costa, D.; Pereira, M.C.; Teixeira, J.P.; Madureira, J.Breath analysis using an electronic nose (eNose) is a technology for exhaled volatile organic compounds (VOCs) that has shown potential in the diagnosis of respiratory diseases. However, the effect of an individual’s characteristics in the exhaled VOCs profile is far from fully understood. This pilot study aimed to identify the relevant characteristics of participants that may influence the VOCs profiles by the...
Impact of renovations on EDC levels and school children's health: bridging scie...
Hatem, G.; Salamova, A.; Haninnen, O.; Faria, A.M.; Costa, C.; Slezakova, K.; Teixeira, J.P.; Madureira, J.Building renovations may yield emissions of various air chemicals that can disrupt normal human endocrine functions. However, only a few endocrine disruptive health outcomes (e.g., respiratory, behavioural, or learning domains) have been comprehensively addressed among susceptible populations, particularly schoolchildren. This project investigates the role of school building renovations on childrenís exposure t...
Fighting occupational risks among Portuguese wildland firefighters: looking at ...
Esteves, F.; Slezakova, K.; Madureira, J.; Vaz, J.; Fernandes, A.; Carmo, M.; Morais, S.; Teixeira, J. P.; Costa, S.Background: Evidence linking wildland firefighters’ occupational exposure and health outcomes is still limited. Cytogenetic endpoints have long been applied in the surveillance of human genotoxic exposures and early effects of genotoxic carcinogens. Therefore, it is of utmost importance to clarify the exposure-induced cytogenetic effects concerning wildland firefighters’ occupational exposure at different time ...
Urinary biomonitoring in firefighters: baseline data of polycyclic aromatic hyd...
Barros, B.; Oliveira, M.; Paiva, M.; Fernandes, A.; Alves, S.; Vaz, J.; Esteves, F.; Slezakova, K.; Alves, M.J.; Madureira, J.; Pereira, M.C.Polycyclic aromatic hydrocarbons (PAHs) are among the most relevant pollutants in the firefighting context and urine the most straightforward and interesting matrix for biomonitoring. Recent studies have found elevated levels of PAH metabolites in firefighters in comparison to the general population. Since Portuguese firefighters are poorly characterized, the aim of this study was to determine the baseline data...
Indoor levels and health risk assessment of volatile organic compounds in Portu...
Slezakova, K.; Costa, C.; Valongo, C.; Teixeira, J.P.; Madureira, J.About indoor levels and health risk assessment of volatile organic compounds in Portuguese homes.
Occupational Exposure of Firefighters in Non-fire Settings
Slezakova, K.; Esteves, F.; Vaz, J.; Alves, M.J.; Madureira, J.; Costa, S.; Fernandes, A.; Teixeira, João Paulo; Morais, S.; Pereira, M.C.Freshwater pollution is a huge concern. A study aiming to evaluate physico-chemical characteristics, microbiota, occurrence of two groups of persistent environmental pollutants with similar chemical properties (polycyclic aromatic hydrocarbons- PAHs and microplastics - MPs) in Alqueva's surface water was performed during 2021.
The burden of heat-related mortality attributable to recent human-induced clima...
Vicedo-Cabrera, A.M.; Scovronick, N.; Sera, F.; Royé, D.; Schneider, R.; Tobias, A.; Astrom, C.; Guo, Y.; Honda, Y.; Hondula, D.M.; Abrutzky, R.Climate change affects human health; however, there have been no large-scale, systematic efforts to quantify the heat-related human health impacts that have already occurred due to climate change. Here, we use empirical data from 732 locations in 43 countries to estimate the mortality burdens associated with the additional heat exposure that has resulted from recent human-induced warming, during the period 1991...
Preservation treatment of fresh raspberries by e-beam irradiation
Elias, M.I.; Madureira, J.; Santos, P.M.P.; Carolino, M.M; Margaça, F.M.A.; Cabo Verde, S.E-beam irradiation was studied as a post-harvest treatment for red raspberries (Rubus idaeus L.). Microbial inactivation (natural microbiota and potential pathogenic bacteria) and bioactive properties (phenolic content, vitamin C content and antioxidant activity and cytotoxicity) of these fruits were evaluated before and after irradiation and during storage of 14 days at 4 °C. A reduction of 2 log CFU/g of meso...
Assessment of indoor air exposure at residential homes: Inhalation dose and lun...
Slezakova, K.; Madureira, J.; Silva, A.I.; Lage, B.; Mendes, A.; Aguiar, L.; Pereira, M.C.; Teixeira, J.P.; Costa, C.Accurate assessment of particulate matter (PM) dose and respiratory deposition is essential to better understand the risks of exposure to PM and, consequently, to develop the respective risk-control strategies. In homes, this is especially relevant in regards to ultrafine particles (UFP; <0.1 μm) which origin in these environments is mostly due to indoor sources. Thus, this study aimed to estimate inhalation do...
