RESUMO

In 2019, there was an environmental catastrophe in Brazil, when more than 5000 tons of unknown origin crude oil invaded beaches and mangroves. Two years later, two monitoring areas were selected to study seahorses' offspring: Massangana River estuary (apparently healthy area) and Cocaia Island (affected area). Thirty-six reproductive events of Hippocampus reidi (Syngnathidae) couples from these two areas were monitored to analyze the offspring. At the apparently healthy area, no newborns with malformations were found. However, the offspring from Cocaia Island showed a mean of 19.73% (±5.23) malformations in newborns. It is argued that the toxic/teratogenic effects of polycyclic aromatic hydrocarbons have affected the population in two ways: directly through the induction of mutations in the germ cells of the species and through a drastic reduction of the population (bottleneck effect) whose density observed today recovered through consanguineous couplings, potentiating deleterious genotypes in the offspring.

RESUMO

Background: Transnational drug trafficking, political unrest, gang violence, and paramilitarism, which are pervasive in Haiti, have resulted in a mental health crisis for the broader Haitian community. This study explores the mental well-being of Haitians in Haiti and the United States by identifying barriers and facilitators to mental health through the lived experiences of men and women. Method: Four Focus group discussions conducted in April and November 2023 engaged 28 participants (20 women and eight men) aged between 23 and 60 years from locations in Haiti (Port-au-Prince, Cite Soleil, Cayes, Cap-Haitien, Saint-Marc) and the United States. Discussions revolved around the definition of mental health, stressors, coping mechanisms, risk and protective factors, and barriers to mental health care. Results: Six principal themes emerged: 1- Chronic Traumatic Stress: continued violence, political instability, unemployment, lack of social support, adverse childhood experiences, family separation, and forced displacement were significant sources of stress. 2- Increased Health Burden: Participants reported experiencing chronic physical and psychological symptoms (i.e., hypertension, anxiety, depression, sleep issues, substance abuse, suicidal ideations, characteristics of post-traumatic stress disorder [PTSD]), which were attributed to Haiti's social, political, and infrastructure collapse. 3- Risk Factors: limited access to mental health services, pervasive hopelessness, scarcity of opportunities, and stigma were identified as significant risks. 4- Future Uncertainty: widespread concerns regarding the future predominated. 5- Multigenerational Concerns: Significant anxiety concerning the mental health and development of children, as well as the functionality of mental health practitioners, was noted. 6- Coping and Protective Factors: Effective coping strategies include mental stimulation, peer support, managing digital consumption, engaging in leisurely activities, such as listening to music, and faith/spirituality. Conclusion: The study's findings underscore the sociopolitical and economic crisis in Haiti, which has resulted in violence and a collapse of political, educational, financial, and health infrastructures. These factors were identified as the primary source of chronic distress, contributing to widespread mental health issues, adverse physical symptoms, and disruption in daily life. The implications for practice, healing, research & policy are discussed.

RESUMO

Introduction: The Eastern Caribbean island of Dominica has experienced diverse negative effects from the North Atlantic hurricane season, including deadly storms like Hurricane Maria in 2017. Vulnerability is increased by geographic location, small island developing state (SIDS) status, and ecosystem characteristics. A variety of negative health effects including stress and anxiety are caused by powerful storms. The perspectives of middle-aged (the "sandwich generation") survivors in this post-storm milieu are understudied. Methods: This phenomenological qualitative study describes the perceptions of middle-aged (35-55 years) Dominicans, purposively recruited with gatekeeper assistance from communities stratified according to four natural hazard vulnerability categories designated by the Climate Resilience Execution Agency for Dominica (CREAD), regarding their lived experiences in the context of severe storms. Data was collected between June and August 2022, using primarily Zoom-based semi-structured, individual interviews (12 of 13), guided by the principles of saturation and maximum variation. Verbatim interview transcripts were thematically analyzed with constant comparison using an ATLAS.ti-supported hybrid deductive-inductive coding frame. Reflexivity and contact summary sheets were used to minimize bias. Results: Ten women and three men from diverse CREAD vulnerability and sociodemographic backgrounds were recruited. Data condensation yielded three organizing themes: (i) "The diverse health effects of severe storms", (ii) "Response to and recovery from severe storms", and (iii) "Preparedness and precaution for severe storms". These themes encapsulated the health impacts of severe storms on Dominicans and elucidated the role of facilitating and barricading resilience factors. Discussion: Severe storms produced direct and indirect mental, social, and physical health impacts on middle-aged Dominicans, including anxiety and burnout. Participants used faith-based, tangible community-based support, and emotional mechanisms to cope with and demonstrate resilience. Better risk communication and early warning systems would improve population readiness. Persistent dispirited attitudes toward storm preparedness among some participants suggest the need for targeted methods to enhance community involvement in disaster planning, including traditional approaches like "coup-de-main" (self-help).

RESUMO

Mass violence events, especially in healthcare settings, have devastating consequences and long-lasting effects on the victims and the community. The rate of violent events in Mexico, especially in hospital settings, has increased since 2006, but has become more evident in 2018. Guanajuato State, located in central Mexico, is among the states most affected by the wave of violence, especially active shooter events. The year 2019 had the highest number of incidents. Therefore, the Silver Code and the components of Safe Hospitals, in accordance with the Hartford consensus and PAHO guidelines, were implemented in the hospitals of the Institute of Public Health of the State of Guanajuato, with a focus on the actions of healthcare personnel to prevent collateral damage. Although subsequently there were still fatalities and injuries in the events involving active shooters in the hospitals, there were no casualties among healthcare personnel, according to data from the Institute of Public Health, Guanajuato State. This paper presents information from the data from General Directorate of Epidemiology to describe the hospital mass violence situation in the State of Guanajuato, Mexico and recounts the step taken to effectively manage and prevent these situations moving forward. Specific recommendations based on international consensus and our experience provided include increasing the level of security checks for people entering the hospital premises, training healthcare personnel on violence-related preparedness and improving management of active shooter events consistent with published evidence, to reduce the possibility of casualties.

RESUMO

Urban areas are undergoing significant changes with the rise of smart cities, with technology transforming how cities develop through enhanced connectivity and data-driven services. However, these advancements also bring new challenges, especially in dealing with urban emergencies that can disrupt city life and infrastructure. The emergency management systems have become crucial elements for enabling cities to better handle urban emergencies, although ensuring the reliability and detectability of such system remains critical. This article introduces a new method to perform reliability and detectability assessments. By using Fault Tree Markov chain models, this article evaluates their performance under extreme conditions, providing valuable insights for designing and operating urban emergency systems. These analyses fill a gap in the existing research, offering a comprehensive understanding of emergency management systems functionality in complex urban settings.

RESUMO

The Samarco/Vale/BHP mine tailing dam breach that took place in Minas Gerais, southeastern Brazil, in 2015, deposited high concentrations of metals and metalloids in the Rio Doce basin, severely impacting freshwater and riverine forest ecosystems. To assess developmental instability of caddisflies in response to the environmental impacts of the dam breach, we investigated the fluctuating asymmetry (FA) in the species Smicridea (Rhyacophylax) coronata (Trichoptera: Hydropsychidae). FA was assessed at individual and populational scales using geometric morphometric methods in the cephalic capsule and mandibles of larvae and also on the forewings of adults, both collected under the impacted condition, and under the least disturbed condition. The levels of FA increased in response to stressors on the forewings at the populational scale, and on the mandibles, at individual scale. These morphological variations in the larval and adult stages may lead to detrimental effects and result in high mortality rates as well as lower adult fitness. Trichoptera forewings are revealed as suitable traits for assessing FA, holding potential for applications in biomonitoring programs. Directional asymmetry levels were higher than FA levels for all traits, and this correlation could be explained by a transition from fluctuating to directional asymmetry in the presence of heightened disturbance. Our results validate the relationship between the impacts from the dam breach and increased developmental instability in this species with likely cascade effects on the insect community.

RESUMO

An environmental disaster caused by the rupture of a mining tailings dam has impacted a large area of the Rio Doce watershed in the Brazilian Atlantic Forest, resulting in unprecedented damage at spatial and temporal scales. The Atlantic Forest is one of the world's most important biodiversity hotspots. A long history of land use conversion has resulted in a highly fragmented landscape. Despite numerous restoration initiatives, these efforts have often biased criteria and use limited species assemblages. We conducted a comprehensive synthesis of the plant community in riparian forests along the Rio Doce watershed. Our work detailed vegetation composition (tree and sapling strata) and examined its relationship with edaphic and landscape factors, aiming to inform restoration projects with scientifically robust knowledge. A total of 4906 individuals from the tree strata and 4565 individuals from the sapling strata were recorded, representing a total of 1192 species from 75 families. Only 0.8% of the tree species and 0.5% of the sapling species occurred in all sampled sectors, with over 84% of the species occurring in a single watershed sector for both strata. We observed a high species heterogeneity modulated by turnover (92.3% in the tree, and 92.7% in the sapling strata) among sites. Overall, our research revealed a gradient of soil fertility influencing species composition across different strata. Additionally, we discovered that preserved landscapes had a positive impact on species diversity within both strata. The species exclusivity in the sampled sites and the high turnover rate imply the need to consider multiple reference ecosystems when restoring the watershed to reduce the risk of biotic homogenization. Finally, the reference ecosystems defined here serve as a basis for the selection of locally particular species in the implementation of restoration projects that aim to improve biodiversity, ecosystem services, and water security.

RESUMO

Combining ecological resilience theory with a phenomenological epistemology, we explored experiential, social, and cultural factors mediating resilience-building with participants from a village destroyed by the 2018 Fuego volcanic eruption in Guatemala. The purpose of the study is to find out what strategies displaced families and communities employ for living through the aftermath of a volcano eruption and for building psychological resilience. We conducted semistructured interviews with nine survivors of the Fuego eruption, now relocated and coping with the loss of community and family members killed in the disaster. Interpretive phenomenological analysis was used to analyze transcripts. The analysis produced four main themes: (i) individual and collective challenges, (ii) social support and protection, (iii) faith and culturally endorsed belief, and (iv) looking to the future. As well as learning more about how a community faced challenges presented by a volcano eruption, the current study has a degree of transferability, with implications for understanding how other communities experience and cope with such events.

RESUMO

BACKGROUND: Disasters are events that bring with them effects that contribute to the disruption of the normality of a population and thus highlight the vulnerabilities of the health system. In Mariana and Brumadinho, the collapse of the dam of ore tailings brought with it several impacts that were felt in the short term and will be felt in the medium and long term. And that by being intensely intertwined with issues of economic and productive nature, has as its meaning an uninterrupted result of its activities. METHODS: Through the DATASUS database, two specific variables were chosen to perform the analysis: the approved amount and the approved value. For this research, a methodological device, the segmented regression line, was used to observe the influences that the disasters that occurred in Mariana and Brumadinho had on the ambulatory health systems. RESULTS: The results of the segmented regression line show that, with Mariana, the amount approved continued to grow throughout the period, which shows that there was no change because of the disaster. There was a reduction in spending. In Brumadinho, regarding the amount approved, there was an upward trend in the disaster's month, which did not change immediately afterwards, and regarding expenditure, the growth pattern was maintained in all three periods. Corroborating this data, the relative and absolute base elements show an increase in the amount approved and in the number of services provided at various posts compared with Minas Gerais. CONCLUSIONS: Based on the findings, it was possible to understand that although disasters exert an influence that may have some effect on the health system, the lack of significance sometimes cannot be interpreted as a lack of impact on the disaster. The segmented regression line outlines some effects that are not conclusive but indicative of a numerical interpretation and a trend interpretation.

RESUMO

INTRODUCTION: The lack of human resources for disease prevention and control is evident in times of health crisis, such as the COVID-19 pandemic. In public health emergencies, the capacity for adequate assistance and guaranteed access to pharmacological treatment are fundamental and contribute to impact reduction. We aimed to analyze the profile, performance, and characteristics related to the self-perception of preparedness among pharmacists who responded to the COVID-19 pandemic in Brazil. METHOD: A cross-sectional study was conducted in two stages: content validation of a questionnaire and its application to a representative sample of pharmacists in Rio de Janeiro. The snowball technique was used to recruit participants. A logistic regression model was adjusted to determine the effects of the factors on the probability of a pharmacist feeling prepared to act during the pandemic. RESULTS: Six experts approved and validated the questionnaire, and 376 pharmacists were included in the study, 60.6 % of whom were in places specially designated by health authorities to diagnose and treat COVID-19. Professionals participated in various activities related to pandemic demands, including medication management and population guidance. Postgraduate degrees increased the odds of participants feeling prepared to act during the pandemic. Furthermore, pharmacists who worked in reference facilities were more likely to feel ready than those who worked in other places. Professionals who knew treatment guidelines were almost three times more likely to feel prepared than the ones without the knowledge of treatment guidelines. Training or guidance on how to act during the pandemic increased pharmacists' odds of feeling prepared by 2.58 times. CONCLUSION: Pharmacists actuated from diagnosis to treatment and participated in the health activities required during the pandemic. Factors contributing to the self-perception of preparedness were identified. Such factors can be targets for interventions to promote the preparedness of the workforce for future health emergencies.

RESUMO

The rupture of the Fundão dam is considered the largest mining failure in history, which had a particularly detrimental impact on fish populations, as the mud from the ore tailings significantly altered the water quality and habitat of Doce River basin. This study aimed to assess the trophic structure of fish communities in areas impacted and not impacted by the dam rupture in the Doce River basin. To evaluate the food web structure, community-wide trophic niche, and trophic positions of fish, stable isotopes of carbon (δ13C) and nitrogen (δ15N) were utilized across ten sites (seven impacted and three control). In general, fish appeared to assimilate resources such as invertebrates, algae, and periphyton, although the importance of each resource varied among sites. The site closest to the dam rupture exhibited a more simplified trophic structure compared to the control sites and those nearer the river mouth. In this site, most fish species occupied a similar trophic position. Trophic niches also exhibited the greatest dissimilarity between the site closest to the dam failure and those farther away from it, with an expansion of trophic niche breadth observed with an increase in the distance from the dam rupture. Our study provided valuable insights into the trophic structure of fish communities within the Doce River basin, shedding light on the trophic ecology of the 59 fish species investigated. We also emphasize the importance of our study for future assessments of ore tailings dam failure disasters and evaluating the effectiveness of mitigation measures for Doce River basin recovery.

RESUMO

The coast of Espírito Santo state (Southeast Brazil) is recognized for its environmental arsenic (As) enrichment and, over the years, mining operations have potentialized it. We aimed to evaluate the effect of Rio Doce discharge on As inputs and the role of iron ore tailings from the Fundão dam disaster in enhancing As contamination in the marine sediment. Two scenarios were evaluated: Predisaster and Postdisaster; dry and wet conditions were considered in each period. High As concentrations were found in the Predisaster (28.44 ± 13.53 µg g-1 ), but a significant increase in As was remarkable during the Postdisaster in the wet season, one year after the disaster (maximum of 58.39 µg g-1 ; geoaccumulation index (Igeo ) Class 3, moderately severe pollution). On that occasion, iron (Fe) oxy-hydroxides from tailings were remobilized from the Rio Doce channel and deposited on the continental shelf bottom. Therefore, chemical interactions among Fe, As, and carbonates were enhanced, resulting in As and Fe coprecipitation and the trapping by carbonate adsorption. Rio Doce discharge seems to be the main factor in As inputs to the inner continental shelf when flooding do not occur previously in samplings, which allows further dispersion of contaminants, although this hypothesis should be tested further.

RESUMO

Liminal periods of disaster solidarity in the aftermath of disaster are a common experience of many survivors. These periods have a specifically ethical component in that people spontaneously engage in collective, altruistic action and magnanimously expand their ethical focus beyond normative social distinctions and hierarchies. Inevitably, however, such solidarity seems to wane, and people return to pre-disaster patterns of interaction. Nevertheless, some individuals move beyond opportune acts of assistance to more extensive reorganisations of their lives during the recovery period and reshape their ethical commitments in new and durable directions. These individuals help make visible marginalised 'others' and draw collaborators to share new ethical visions. Based on observational and interview data collected after Hurricane María (2017) in a mountainous Puerto Rican municipality and employing the framework of virtue ethics, this paper examines the differential effects of disaster solidarity on survivors' ethical responses and the different contributions these make to society.

RESUMO

Resumo: O artigo, na forma de ensaio, sistematiza uma trajetória profissional de experiências interdisciplinares e socialmente engajadas em torno da análise e prevenção de acidentes e desastres nos últimos 40 anos. O trabalho acadêmico se desenvolveu principalmente no âmbito da pesquisa e pós-graduação na saúde pública brasileira impulsionado pelo movimento sanitarista e a construção do Sistema Único de Saúde (SUS) em sua busca por democracia, justiça social e sanitária. A base empírica envolveu ações de vigilância em saúde dos trabalhadores e ambiental organizadas em redes protagonizadas pelo SUS em conjunto com universidades, sindicatos, movimentos sociais, organizações não governamentais (ONG) ambientalistas e Ministérios Públicos. Eventos de maior complexidade socioambiental em setores como siderurgia, petroquímico, mineração, agronegócio e energia forjaram a busca por novos referenciais epistêmicos e interdisciplinares que abarcam duas novas justiças: a ambiental e a cognitiva. Este artigo apresenta essa trajetória de contribuições conceituais em três movimentos a partir da década de 1980 até os dias atuais, cada qual correspondendo a um contexto sociopolítico e institucional, para pensar movimentos de transição paradigmática na análise e prevenção de acidentes e desastres numa perspectiva interdisciplinar. Finaliza-se com a sugestão de prevenção abissal e emancipatória para enfrentar diferentes crises da atualidade, como a ambiental, a sanitária, a democrática e a civilizatória.

Resumen: El artículo, en forma de ensayo, sistematiza una trayectoria profesional de experiencias interdisciplinarias y socialmente comprometidas en torno al análisis y la prevención de accidentes y desastres en los últimos 40 años. El trabajo académico se desarrolló principalmente en el ámbito de la investigación y postgrado en Salud Colectiva brasileña, impulsado por el movimiento sanitario y la construcción del Sistema Único de Salud (SUS) en su búsqueda por democracia, justicia social y sanitaria. La base empírica involucró acciones de vigilancia en salud y ambiental de los trabajadores, organizadas en redes protagonizadas por el SUS en conjunto con universidades, sindicatos, movimientos sociales, organizaciones no gubernamentales ambientalistas y Ministerios Públicos. Los acontecimientos de mayor complejidad socioambiental en sectores como la siderurgia, el petroquímico, la minería, el agronegocio y la energía han llevado a la búsqueda de nuevas referencias epistémicas e interdisciplinarias que abarcaron dos nuevas formas de justicia, la ambiental y la cognitiva. El artículo sistematiza esa trayectoria de contribuciones conceptuales en tres movimientos a partir de la década de 1980 hasta los días actuales, cada cual, correspondiendo a un contexto sociopolítico e institucional, para pensar movimientos de transición paradigmática en el análisis y prevención de accidentes y desastres desde una perspectiva interdisciplinaria. Se finaliza con la sugerencia de prevención abisal y una prevención emancipadora para enfrentar diferentes crisis de la actualidad, como la ambiental, la sanitaria, la democrática y la de civilización.

Abstract: The article, in the form of an essay, systematizes a 40-year-long professional trajectory of interdisciplinary and socially engaged experiences around the analysis and prevention of accidents and disasters. This study was mainly developed within the scope of research and postgraduate studies in Public Health in Brazil, driven by the sanitarian movement and the construction of Brazilian Unified National Health System (SUS) in its search for democracy and social and health justices. Its empirical basis involved workers' health and environmental surveillance actions organized in networks led by SUS in conjunction with universities, unions, social movements, environmental nongovernmental organizations (NGO), and Public Prosecutors' Offices. Events of greater socio-environmental complexity in sectors such as steel, petrochemicals, mining, agribusiness, and energy forged the search for new epistemic and interdisciplinary references that encompassed two new justices, i.e., environmental and cognitive. This essay systematizes this trajectory of conceptual contributions in three movements from the 1980s to the present day (each corresponding to a socio-political and institutional context) to reflect on paradigmatic transition movements in the analysis and prevention of accidents and disasters from an interdisciplinary perspective. It ends by suggesting abyssal and emancipatory prevention to face different current crises, including environmental, health, democratic, and civilizing ones.

RESUMO

ABSTRACT Objective: to identify courses available online by national civil defense bodies in Brazil and Mexico to assist in the additional training of healthcare professionals for disasters. Method: an exploratory descriptive study, based on a qualitative approach, using technological prospecting methodology, carried out on the official Civil Defense websites in Brazil and Mexico. Results: ten courses offered by the Government of Mexico's National Center for Disaster Prevention were found, nine of which were short-term and one offered as vocational training. All of these courses were synchronous. In Brazil, 36 courses were located, all in asynchronous formats, with durations varying between 20 and 50 hours. Although the courses presented programmatic content that included activities inherent to healthcare professionals, none of them made specific mention of professionals in this area as the target audience. Conclusion: the prospective study reinforces that Information and Communication Technologies for distance education present themselves as an alternative present in both countries in terms of additional training for disasters, although not yet specifically aimed at healthcare professionals. The need to include this area of interdisciplinary and multi-professional content reflects gaps in sector integration.

RESUMEN Objetivo: identificar cursos disponibles en línea por los organismos nacionales de defensa civil en Brasil y México para ayudar en la capacitación adicional de profesionales de la salud para desastres.

RESUMO

In the 2020s, understanding disaster risk requires a strong and clear recognition of values and goals that influence the use of political and economic power and social authority to guide growth and development. This configuration of values, goals, power and authority may also lead to concrete drivers of risk at any one time. Building on previous disaster risk frameworks and experiences from practice, since 2010, the 'Forensic Investigations of Disasters (FORIN)' approach has been developed to support transdisciplinary research on the transformational pathways societies may follow to recognise and address root causes and drivers of disaster risk. This article explores and assesses the achievements and failures of the FORIN approach. It also focuses on shedding light upon key requirements for new approaches and understandings of disaster risk research. The new requirements stem not only from the uncompleted ambitions of FORIN and the forensic approach but also from dramatic and ongoing transformational changes characterised by climate change, the coronavirus disease 2019 (COVID-19) pandemic and the threat of global international confrontation, among other potential crises, both those that can be identified and those not yet identified or unknown. Contribution: Disasters associated with extreme natural events cannot be treated in isolation. A comprehensive "all risks" or "all disasters" approach is essential for a global transformation, which could lead to a better world order. To achieve this, an Intergovernmental Panel for Disaster Risk is suggested to assess risk science periodically and work towards sustainability, human rights, and accountability, within a development and human security frame and on a systemic basis and integrated perspective.

RESUMO

The oil spill environmental sensitivity index is a key tool for preventing and dealing with environmental disasters caused by oil spills. This study aims to review the available literature on the subject and highlight the importance of methodological advances to improve how the index is applied in continental areas, especially in regions crossed by pipelines. Most current mapping techniques focus on coastal areas and fail to consider the stretches of land that are vulnerable to geodynamic natural disasters. In this context, the need to implement environmental sensitivity indices specific for pipelines has become urgent. This study also presents an overview of the main accidents around the world and a detailed analysis of the history of Brazilian disasters related to oil spills along continental stretches, with a focus on pipelines and natural disasters. In addition, this work highlights the importance of carrying out new research in mountainous areas of Brazil and is aimed at preventing Natechs (natural hazard triggering technological disasters) and improving contingency plans. As a result, several pathways have been identified, which involves the necessity of resolving gaps in terrestrial environmental sensitivity mapping methodologies, particularly as applied to pipelines. Furthermore, solutions must be capable of integrating terrestrial, fluvial, coastal, and maritime environmental sensitivity mapping techniques. Moreover, the need to implement dynamic risk monitoring systems in real time is critical to help manage such a complex problem.

RESUMO

The Fundão Dam failure has been the most significant environmental disaster in Brazil. The catastrophe released large amounts of mining waste into the environment, including toxic metals/metalloids, which are recognized to induce carcinogenic effects. The urinary levels of 8-hydroxy-2'-deoxyguanosine (8OHdG), a widely accepted oxidative stress and carcinogenesis biomarker, provide a potential tool for assessing the disaster's health implications. This study investigated the association between urinary levels of some toxic metals/metalloids and 8OHdG in Brazilian individuals living in areas affected by the Fundão dam failure. Urinary concentrations of arsenic (As), cadmium (Cd), mercury (Hg), nickel (Ni), and lead (Pb) were determined using inductively coupled plasma mass spectrometry, while 8OHdG was analyzed by liquid chromatography-tandem mass spectrometry. Non-parametric bootstrap regression was used to estimate the associations between the urinary levels of toxic elements and 8OHdG. The results showed that except for Hg, urinary concentrations of all metals/metalloids analyzed here exceeded the reference ranges for the Brazilian population. The regression analysis revealed that As (0.337; CI 95%: 0.203; 0.474), Cd (0.268; CI 95%: 0.036; 0.520), and Ni (0.296; CI 950.108; 0.469) were positively associated with creatinine-adjusted urinary 8OHdG levels. Associations were not found for Hg (0.0122; CI 95%: -0.155; 0.183) and Pb (0.201; CI 95%: -0.040; 0.498). The current findings suggest that high exposure to toxic metals/metalloids might increase 8OHdG levels with potential adverse health effects. This study is the first one in which the relationship between toxic metals/metalloids and oxidative stress biomarkers is investigated in populations affected by environmental disasters. Further prospective studies are necessary to monitor exposure levels and explore additional health impacts.
