Occupational exposure to wildland firefighting and its effects on systemic DNA ...
Esteves, Filipa; Madureira, Joana; Costa, Carla; Pires, Joana; Barros, Bela; Alves, Sara; Vaz, Josiana; Oliveira, Marta; Slezakova, KlaraBackground: Portugal is among the European Union countries more devastated by forest fires. Wildland firefighters are at the forefront of this battle, facing exposure to a wide range of harmful pollutants. Epidemiological studies have highlighted a potential link between occupational firefighting exposure and several diseases, including cancer. To date, very few studies have explored the biological mechanisms a...
Baseline data and associations between urinary biomarkers of polycyclic aromati...
Barros, Bela; Paiva, Ana Margarida; Oliveira, Marta; Alves, Sara; Esteves, Filipa; Fernandes, Adília; Vaz, Josiana; Slezakova, Klara; Costa, SolangeIntroduction: Available literature has found an association between firefighting and pathologic pathways leading to cardiorespiratory diseases, which have been linked with exposure to polycyclic aromatic hydrocarbons (PAHs). PAHs are highlighted as priority pollutants by the European Human Biomonitoring Initiative in occupational and non-occupational contexts. Methods: This cross-sectional study is the first to...
Exploring clinical trials to manage firefighters’ sleep quality: a PRISMA compl...
Alves, Sara; Vaz, Josiana; Fernandes, AdíliaSleep research has grown over the past decades and investigators are deeply involved in studying sleep and its impact on human health and body regulation. Despite the understanding that insufficient sleep is strongly linked to the development of several disorders, unsatisfactory sleep exposes health and safety to innumerous risks. The present study aims to review and analyze the main results of clinical trials,...
Portuguese wildland firefighters: assessing exposure and cytogenetic effects in...
Pires, Joana; Esteves, Filipa; Slezakova, Klara; Madureira, Joana; Vaz, Josiana; Fernandes, Adília; Pereira, Maria do Carmo; Morais, SimoneIARC has recently listed occupational exposure as a firefighter carcinogenic to humans. However, firefighter is among the least studied occupations. The goal of the present study was to assess the level of cytogenetic damage in buccal mucosa (first-contact exposure tissue) of Portuguese firefighters during the pre- wildland fire season, as well as, to evaluate firefighters ́ exposure to particulate matter (PM) ...
Firefighters' sleep quality: results of a study in The Northeast of Portugal
Alves, Sara; Esteves, Filipa; Silva, Francisca; Queiroga, Felisbina; Costa, Solange; Slezakova, Klara; Alves, Maria José; Pereira, Maria do CarmoThe aim of this study was to evaluate and describe the overall sleep quality of firefighters. Application of the Portuguese version of the Pittsburgh Sleep Quality Index (PSQI) to firefighters, from the Northeast of Portugal, who accepted to participate in the study. Data collected between June 2021 and July 2022. The PSQI global score classified participants as 36,9% of participants as poor sleepers, although ...
Fighting occupational risks among Portuguese wildland firefighters: looking at ...
Esteves, Filipa; Slezakova, Klara; Madureira, Joana; Vaz, Josiana; Fernandes, Adília; Pereira, Maria do Carmo; Morais, Simone; Teixeira, João PauloBackground: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 p...
Response surface methodology applied to essential oil extraction of eucalyptus ...
Hached, Hanine; Pedrosa, Mariana C.; Heleno, Sandrina; Barros, Lillian; Vaz, Josiana; Carocho, MarcioPlant volatiles are secondary metabolites with a wide range of applications in several industries, namely the textile, food, pharma, and perfumery. These molecules are usually from three major groups, the terpenoid, phenylpropanoid/benzenoid and fatty acid derivatives group. This work focused on applying the response surface methodology technique towards optimizing the yield in essential oils of Eucalyptus glob...
Occupational Exposure of Firefighters in Non-fire Settings
Slezakova, Klara; Esteves, Filipa; Vaz, Josiana; Alves, Maria José; Madureira, Joana; Costa, Solange; Fernandes, Adília; Teixeira, João PauloThis work assessed firefighters’ exposure to particulate matter (PM) in non-fire work settings during pre-fire season, as a baseline for the respective occupational exposure characterization. Indoor and outdoor air sampling was conducted for two weeks in pre-fire season of 2021 in seven fire corporations (FC1-FC7) in north of Portugal. PM fractions (PM2.5, PM10) were continuously monitored concurrently in indoo...
Exposure to particulate matter in fire stations: preliminary results
Slezakova, Klara; Esteves, Filipa; Barros, Bela; Vaz, Josiana; Alves, Maria José; Madureira, Joana; Costa, Solange; Oliveira, Marta; Fernandes, AdíliaFirefighters are at increased risk for many types of health diseases (IARC, 2010). While most of the studies on this topic focus on exposures and their impacts due to the fire combats (Oliveira et al., 2017), firefighters spend large portions of their day-by-day shift within the fire stations, where they can be exposed to a variety of air pollutants, including particulate matter (PM), i.e., a known carcinogen. ...
Firefighters exposure to fire emissions: Impact on levels of biomarkers of expo...
Oliveira, Marta; Costa, Solange; Vaz, Josiana; Fernandes, Adília; Slezakova, Klara; Delerue-Matos, Cristina; Teixeira, João Paulo; Carmo Pereira, MariaFirefighters represent one of the riskiest occupations, yet due to the logistic reasons, the respective exposure assessment is one of the most challenging. Thus, this work assessed the impact of firefighting activities on levels of urinary monohydroxyl-polycyclic aromatic hydrocarbons (OHPAHs; 1-hydroxynaphthalene, 1-hydroxyacenaphthene, 2-hydroxyfluorene, 1-hydroxyphenanthrene, 1-hydroxypyrene, 3-hydroxybenzo(...
