Morphological and elemental characterization of fine and ultrafine particulate matter generated from fires Gabriel Sousa, Rui Azevedo, Agostinho Almeida, Simone Morais, Cristina Delerue-Matos, Xianyu Wang, Francisca Rodrigues, Maria Freitas, Marta Oliveira Environmental Research, 2026 Fire emissions aggravate air pollution by releasing several hazardous pollutants, including respirable particulate matter (PM). Evidence on fires contribution to fine and ultrafine PM is scarce, principally in real fire scenarios. This study presents the first morphological and elemental composition of fine (PM 2.5 , PM 156nm ) and ultrafine (PM 50.4nm , PM 30.8nm , PM 14.9nm ) fractions of PM released during three controlled structure (CSF) and two prescribed forest (PFF) fires. Total median PM levels were 9 times higher in CSF emissions than in PFF [11.13 (1.245-228.5) mg/m 3 versus 1.232 (0.5458-1.920) mg/m 3 ), with fine PM being 13 and 3 times higher than ultrafine PM in CSF and PFF, respectively ( p >0.05). The morphological analysis revealed the prevalence of organic matter in fine/ultrafine PM, with several particles of bright contrast with distinct shapes and sizes, which were more prominent in PFF. The electron dispersive spectroscopy and elemental mapping analysis suggested the presence of sulphates, carbonates, and chlorides of sodium, magnesium, potassium, and calcium (biomass combustion), and stainless-steel particles associated with handling of heavy machinery in PFF. Also, particles of PbCl 2 and PbO (combustion of paints/solder) were observed in CSF. Zn, Cu, Cr, and Ni, as well as Co (in PFF), and Pb (in CSF) were the predominant elements in fire generated PM. Toxic and (possible/probable) carcinogenic elements represented up to 29.3% and 33.1% of fine and ultrafine fire generated PM, respectively. This work advances the knowledge on fire-generated PM highlighting the need for further studies on fire chemistry, PM behaviour, and realistic huma exposure and health risk assessments.
Micronucleus assay in buccal and urothelial epithelial cells of wildland firefighters exposed to wildfire smoke Filipa Esteves, Joana Madureira, Bela Barros, Sara Alves, Josiana Vaz, Marta Oliveira, Klara Slezakova, Adília Fernandes, Maria do Carmo Pereira, Simone Morais, Stefano Bonassi, João Paulo Teixeira, Solange Costa Journal of Hazardous Materials, 2025 Occupational exposure as a firefighter is classified as carcinogenic to humans. However, information on the biological effects of wildland firefighting remains limited. This study aimed to assess genotoxicity in a group of wildland firefighters and evaluate the contribution of total concentration of urinary hydroxylated polycyclic aromatic hydrocarbons (ΣOHPAHs) to selected endpoints. A group of 59 northern Portuguese wildland firefighters (mean age: 35.5 ± 9.0 years) was evaluated before and during the wildfire season. Sociodemographic, lifestyle, occupational-related information was collected via questionnaire. The micronucleus (MN) assay in buccal and urothelial cells was applied to paired samples to assess the association with exposure, as indicated by urinary ΣOHPAHs levels. The risk of MN formation in urothelial cells was over twofold higher during the wildfire season [Frequency Ratio (FR): 2.13, 95 % CI: 1.99-2.27, p = 0.01]. A 35 % increase in MN frequency in buccal cells was observed during the wildfire season (FR: 1.35, 95 % CI: 0.76-2.40, p > 0.05). Urinary ΣOHPAHs exhibited a significant positive association with MN‰ in urothelial cells (FR:1.04, 95 % CI: 1.01-1.08, p < 0.05). This study provides the first assessment of MN frequency in urothelial cells of wildland firefighters, offering novel evidence of genotoxic risks and potential long-term health impacts associated with wildland firefighting.
Bioactive compounds from Actinidia arguta fruit as a new therapeutic approach to cutaneous melanoma Filipa Teixeira, Marta Oliveira, Francisca Rodrigues Pharmacological Research Natural Products, 2025 The use of natural products in disease prevention and therapy has gained considerable momentum, largely due to their abundance in health-beneficial bioactive constituents. Among these, Actinidia arguta (Siebold & Zucc.) Planch. ex Miq. (Actinidiaceae), commonly referred to as kiwiberry, has emerged as a promising candidate owing to its rich composition of phenolic acids, flavonoids, organic acids, vitamins, carotenoids, and dietary fibers. These compounds are associated with a wide array of biological functions, including antioxidant, anti-inflammatory, immunoregulatory, neuroprotective, and anticancer effects. Recent interest has grown around their application in managing cutaneous melanoma (CM), a highly aggressive form of skin cancer marked by rapid progression, early metastasis, and frequent therapeutic resistance. Despite the development of innovative therapies, outcomes for advanced CM remain poor, pointing to an urgent need for alternative strategies. Preliminary research suggests that bioactives from A. arguta may influence the melanoma progression by interfering with critical molecular pathways, particularly MAPK, PI3K/AKT, and Wnt/β-catenin, alongside reducing oxidative damage, impairing tumor cell growth and migration, and enhancing apoptotic responses. These findings point to the potential of kiwiberry-derived compounds as supportive or alternative treatments in melanoma care. Nevertheless, several challenges persist, including variability in compound composition, lack of formulation standardization, and limited systemic bioavailability. Addressing these limitations is essential for future clinical translation. Further studies, particularly in vivo and clinical trials, are needed to confirm both efficacy and safety. This review aims to summarize the current evidence on the role of kiwiberry fruit-derived compounds in CM, offering insight into their mechanisms of action and possible integration into complementary therapeutic approaches. • A. arguta as a promising natural option to conventional cutaneous melanoma therapies • High phytochemical content offers robust anti-cancer properties • Altered signaling pathways in melanoma as key to developing improved treatments • Potential of natural compounds from A. arguta to target altered signaling pathways • Extremely high potential of using kiwiberries as an adjuvant to conventional therapies
Impact of wildfire emissions exposure on the associations between levels of lung injury, lipid peroxidation, DNA oxidation, and exposure biomarkers Bela Barros, Ana Margarida Paiva, Rui Azevedo, Sara Alves, Filipa Esteves, Adília Fernandes, Josiana Vaz, Maria José Alves, Klara Slezakova, João Paulo Teixeira, Solange Costa, Agostinho Almeida, Marta Oliveira, Simone Morais Science of the Total Environment, 2025 Firefighters face increased risks of developing cardio-respiratory diseases and cancer. This study aimed, for the first time, to simultaneously characterize several biomarkers of effect (lung injury by Clara cell 16 -CC16, lipid peroxidation by 8-isoprostane-8-iso, and DNA oxidation by 8-hydroxy-2-deoxyguanosine-8-OHdG) and exposure (polycyclic aromatic hydrocarbons metabolites - 6 OHPAHs and 17 metal(loid)s) in (pre- and post-exposure) paired urine samples of wildland firefighters, while exploring their inter-/intra-associations and accounting for tobacco consumption. Wildfire combat influenced the levels of CC16 (+39 %), 8-iso (+33 %), 8-OHdG (-13 to +19 %), individual and sum of OHPAHs (+75-211 %), and metal(loid)s (up to 43 %, p > 0.05: lithium, zinc, antimony, and lead); post-exposure increments were more evident among non-smokers. Post-exposure (individual and sum) OHPAHs and some metal(loid)s (copper, cadmium, barium, antimony, copper, lead, zinc, selenium, and rubidium) were positively associated with CC16, 8-iso and/or 8-OHdG (0.609 < r < 0.838; 0.001 < p < 0.047). Spearman's correlations and principal component analysis highlighted CC16 as the best discriminant effect biomarker of wildland firefighting, correlating positively with individual and sum of OHPAHs, cadmium, barium and copper (0.647 < r < 0.764; 0.006 < p < 0.031). Cumulative exposure to wildfires and tobacco contributed to positive correlations (0.587 < r < 0.715; 0.009 < p < 0.045) between lipid peroxidation and arsenic, antimony, lead, and copper, and between DNA oxidation and lead. Smoking firefighters presented higher OHPAHs baseline concentrations (2- to 14-fold), and lung injury and DNA oxidation induced by cadmium, copper, strontium, cesium, barium and thallium (0.661 < r < 0.709; 0.022 < p < 0.038). Given firefighter's carcinogenic risks, performing similar studies in larger groups is crucial to enhance risk assessment by establishing a well-defined panel of effect and exposure biomarkers.
Impact of occupational exposure to wildfire events on systemic inflammatory biomarkers in Portuguese wildland firefighters Filipa Esteves, Joana Madureira, Bela Barros, Sara Alves, Joana Pires, Sandra Martins, Marta Oliveira, Josiana Vaz, Klara Slezakova, Maria do Carmo Pereira, Adília Fernandes, Simone Morais, João Tiago Guimarães, Stefano Bonassi, João Paulo Teixeira, Solange Costa Environmental Research, 2025 While occupational exposure as a firefighter is considered a dangerous occupation, research on the underlying mechanisms remains limited, particularly in wildland firefighters. Inflammation, a key effect of wildfire exposure, plays a significant role in the development of various diseases. The current study aims to investigate the impact of wildland firefighting exposure on the levels of pro-inflammatory systemic biomarkers. A pre-post study design investigated 59 wildland firefighters comparing data collected after participation in a wildfire event (Phase II) with data obtained before wildfire season (Phase I). Data on demographics, lifestyle, health and occupational-related factors were assessed. Exposure factors, such as fire combat (e.g., exposure duration), were also registered. Inflammatory biomarkers (i.e. interleukin-6 [IL-6], interleukin-8 [IL-8], tumor necrosis factor α [TNF-α] and high-sensitivity C-reactive protein [hs-CRP]) and hydroxylated polycyclic aromatic hydrocarbons metabolites (1-OHNaph+1-OHAce, 2-OHFlu, 1-OHPhen, 1-OHPyr) were analysed in blood and urine samples, respectively. Serum IL-8 and IL-6 levels were significantly increased after wildland fire combat. IL-8 levels were 2.62 times higher (95 % CI: 1.96-3.50; p < 0.01), whereas IL-6 levels were 1.25 times higher (95 % CI: 1.00-1.57; p = 0.04). Furthermore, IL-8 levels were significantly correlated with urinary 2-hydroxyfluorene levels and fire combat duration (>12 h). In addition, the mean hs-CRP level, in both phases, was above 3.0 mg/L, indicating a potential risk for cardiovascular events. Given the long-term health implications of firefighting occupational exposure, biomonitoring and early detection of occupational risks are essential for protecting firefighters' health. Protective measures must be urgently implemented to enhance occupational health and strengthen preventive strategies in this sector.
Air Pollution and Health Impacts of Wildfire Seasons: Insights from Northern Portugal Bela Barros, Marta Oliveira, Simone Morais Water Air and Soil Pollution, 2025 Wildfires emit significant amounts of pollutants into the atmosphere, which can cause a range of health effects, from acute symptoms to increased emergency visits, hospital admissions, and even mortality in the general population. This study aimed to characterize, for the first time, the associations between wildfire season with indicators of public human health surveillance in the Northern region of Portugal (2019–2022). Daily air pollutant data [particulate matter with aerodynamic diameter less than 10 µm (PM₁₀) and 2.5 µm (PM₂.₅), ozone (O₃), and itrogen dioxide (NO₂)], monthly emergency room visits, and regional expenses with medication dispensing were characterized and mortality impacts were estimated. Wildfire season was responsible for higher PM₁₀ and PM₂.₅ (up to + 90%), O₃ (up to + 51%), and NO₂ (up to + 39%); some days (up to 8%) surpassed limits established by national regulations and/or WHO guidelines. The total burned area correlated with monthly levels of PM₁₀, PM₂.₅, and O₃ (0.467 < r < 0.943; p ≤ 0.039). Wildfire season months presented more emergency visits to urgent care (up to + 128%; p > 0.05) and regional monthly health costs due to outpatient medication for blood volume and electrolyte imbalance (+ 12–31%; p > 0.05). During wildfire season, the number of urgent pediatric visits correlated with O₃ levels (r = 0.606, p = 0.013). During large forest fires (> 100 hectares), a maximum of 36 and 330 estimated deaths were attributed, respectively, to short-term and long-term exposure to PM₁₀, PM₂.₅, O₃, and NO₂ above WHO guidelines. The findings highlight the need to improve wildfire management and public health policies, including through a stronger engagement of the general population, and promote the implementation of more effective preventive and mitigation strategies to protect the health of affected communities during wildfire season.
Human exposure to polycyclic aromatic hydrocarbons during structure fires: Concentrations outside and inside self-contained breathing apparatus and in vitro respiratory toxicity Joana Teixeira, Maria João Bessa, Cristina Delerue-Matos, Bruno Sarmento, Alice Santos-Silva, Francisca Rodrigues, Marta Oliveira Environmental Pollution, 2025 Structure fires release several health-hazardous compounds, including polycyclic aromatic hydrocarbons (PAHs), and the use of self-contained breathing apparatus (SCBA) is mandatory to protect firefighters’ airways. The characterization of PAHs released during structure fires is scarce, principally in European countries. This work elucidates the mechanisms of toxic effects associated with human exposure to PAHs released during structure fires, by assessing for the first time, the levels in the breathable air of sapper firefighters with and without the use of SCBA. An in vitro co-culture model of air-blood barrier was used to evaluate respiratory toxicity. Concentrations of total PAHs (∑PAHs) inside the burning structure were 8.20–19.8 times higher than the values monitored inside fire stations (11.5–28.0 μg/m 3 versus 1.41 μg/m 3 ; p < 0.005) and 2688–5872 times higher than the levels detected inside the SCBA used during the fire events. Levels of carcinogenic PAHs were 6.90–20.5 times higher than observed for the control group ( p ≤ 0.005). Inside to outside ratios (<1) suggested the contribution of PAHs from fires to the levels detected inside the protection system. Exposure to fire emissions increased the risk of lung cancer. The use of SCBA system substantially reduced exposure to PAHs, still levels detected outside/inside the SCBA facemask significantly reduced the viability of alveolar and bronchial cell lines (<70 %). Benzo( a )pyrene (100 %), naphthalene and phenanthrene (97.5 %), benzo(b+j)fluoranthene (90 %), and fluorene (87.5 %) found inside the SCBA mask were able to permeate the co-culture model of air-blood barrier. More studies need to corroborate these preliminary findings and evaluate the synergic effect of fire effluent complex mixtures and their contribution to respiratory toxicity. • The ∑PAH levels were 2.69 × 10 3 -5.87 × 10 3 times lower in the air inside than outside the SCBA. • The levels of ∑PAH carc were 6.90–20.5 times higher than those found at fire stations. • The SCBA system reduced exposure, and available occupational limits were not exceeded. • The PAHs found inside SCBA reduced the viability of alveolar and bronchial cell lines. • Some PAHs permeated the air-blood barrier model and may cause cell cytotoxicity.
Effectiveness of Self-Contained Breathing Apparatus: An Observational Study on Exposure to Polycyclic Aromatic Hydrocarbons and Associated Respiratory Risks Joana Teixeira, Cristina Delerue-Matos, Alice Santos-Silva, Francisca Rodrigues, Marta Oliveira Fire, 2025 Background: An effective risk assessment and management methodology is essential to minimize/mitigate health risks associated with firefighting activities. The use of a self-contained breathing apparatus (SCBA) is mandatory during structure fires to protect firefighters from hazardous fire effluents, yet the protectiveness of the SCBA system has rarely been evaluated. Objective: This study characterizes, for the first time, the levels of 18 polycyclic aromatic hydrocarbons (PAHs) inside the SCBA facemask, during 7 structure-firefighting exercises and estimates associated respiratory risks. Methods: Cotton disk samples were collected via passive air sampling and analyzed using liquid chromatography with fluorescence and UV–Vis detection. Results: Levels of total PAHs (∑PAHs: 9.17–29.6 ng/m3) and ∑PAHscarcinogenic (0.41–5.73 ng/m3) were below the occupational limits defined by governmental agencies. The low-molecular-weight PAHs were predominant (79.5–91.4%), and the (possible/known) carcinogenic naphthalene (0.26–2.00 ng/m3), anthracene (0.088–0.31 ng/m3), chrysene (0.046–0.39 ng/m3), benzo(b+j)fluoranthene (0.18–0.40 ng/m3), and benzo(a)pyrene (0.041–0.18 ng/m3) were detected in all samples. The respiratory health risk analysis demonstrated negligible risks associated with the inhalation of PAHs. A health principal component analysis could identify firefighters at increased respiratory risk. Conclusions: The effectiveness of SCBA was demonstrated, reinforcing the need to ensure its correct use during all the phases of structure fires, including during overhaul.
Occupational exposure to wildland firefighting and its effects on systemic DNA damage Filipa Esteves, Joana Madureira, Carla Costa, Joana Pires, Bela Barros, Sara Alves, Josiana Vaz, Marta Oliveira, Klara Slezakova, Adília Fernandes, Maria do Carmo Pereira, Simone Morais, Vanessa Valdiglesias, Stefano Bonassi, João Paulo Teixeira, Solange Costa International Journal of Hygiene and Environmental Health, 2025 BACKGROUND: 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 associated with such exposure. The present longitudinal study aims to assess changes in early effect biomarkers following wildland firefighters' occupational exposure to a real wildfire event. METHODS: Paired blood samples from 59 healthy Portuguese wildland firefighters were collected at two different time points: before wildfire season and after a fire event during wildfire season. Sociodemographic variables (e.g., age, sex) and work-related factors (e.g., years of service) were assessed via a self-reported questionnaire. Levels of early effect biomarkers, such as primary DNA damage and oxidative DNA damage (oxidised purines) were assessed via comet assay. DNA double-strand breaks (DSBs) were evaluated by phosphorylated H2AX (γH2AX). Moreover, hydroxylated polycyclic aromatic hydrocarbon metabolites (OHPAHs) and metal(loid)s were quantified in urine samples. The influence of urinary OHPAHs, urinary metal(loid)s, and other exposure-related factors (e.g., firefighting duration) on changes (Δ) in early effect biomarkers (post-vs. baseline levels) was investigated. RESULTS: Firefighting activities led to a significant increase in both primary DNA damage and oxidative DNA damage by 22 % (95 % CI: 1.11-1.35; p < 0.05) and 23 % (95 % CI: 1.04-1.45; p < 0.05), respectively. Results from linear regression revealed that per each unit increase of urinary 2-hydroxyfluorene (2-OHFlu) (μmol/mol creatinine), the risk of ⧍ oxidative DNA damage increased by 20 % [FR: 1.20 (1.09-1.32); p < 0.01]. Additionally, each unit increase in urinary cesium (Cs) (μg/L) resulted in a significant 4 % increase in Δ primary DNA damage [FR: 1.04 (1.01-1.06); p < 0.05] and a 3 % increase in Δ oxidative DNA damage [FR: 1.03 (1.01-1.05); p < 0.05]. Post-exposure levels of γH2AX were significantly correlated with urinary 2-OHFlu levels assessed after firefighting (r = 0.30; p < 0.05). Furthermore, exposure duration and reported breathing difficulties during firefighting were significantly associated with increased levels of primary DNA damage. CONCLUSION: Results obtained provide insights into the potential human health effects of wildland firefighting occupational exposure at the genetic and molecular levels, offering new and important mechanistic data. These findings are crucial for implementing health and safety measures, recommendations, and best practices to mitigate occupational risks and protect the health of wildland firefighters.
