The early psychological impacts of the Deepwater Horizon oil spill on Florida and Alabama communities

Gulf Coast Resilience Coalition: An Evolved Collaborative Built on Shared Disaster Experiences, Response, and Future Preparedness

OBJECTIVE

For close to a decade, the Gulf Coast of the United States has been in almost constant disaster recovery mode, and a number of lessons have been learned concerning disaster recovery and behavioral health. The purpose of this report was to describe the natural development of a Gulf Coast Resilience Coalition (GCRC).

METHODS

The GCRC methods began with state-specific recovery goals following Hurricane Katrina in 2005 and transitioned to a shared multistate and multidiscipline coalition. The coalition's effectiveness is demonstrated through continuation, procurement of funding to provide response services, and increased membership to ensure sustainability.

RESULTS

The coalition has enhanced response, recovery, and resilience by providing strategic plans for dissemination of knowledge; post-disaster surveillance and services; effective relationships and communication with local, state, and regional partners; disaster response informed by past experience; a network of professionals and community residents; and the ability to improve access to and efficiency of future behavioral health coordination through an organized response.

CONCLUSIONS

The GCRC can not only improve readiness and response, but work toward a shared vision of improved overall mental and behavioral health and thus resilience, with beneficial implications for the Gulf South and other communities as well.

Perception of risk for Domoic Acid related health problems: A Cross-cultural study

Risk perception is a complex process that refers to the way people approach, think about and interpret risks in their environment. An important element of risk perception is that it is culturally situated. Since HAB's can present a health risk in many places around the world, looking at cultural parameters for understanding and interpreting risks are important. This study examined how two different groups of people perceive the potential health risks of low level exposure to domoic acid (DA) through razor clam consumption. The risk perceptions of Washington State, USA coastal dwelling Native American nations (NA) were compared to that of a community sample of recreational razor clam harvesters (CRH). Overall, the findings support the hypothesis that cultural and community specific contexts impact the perception of risk of a DA related illness. Specifically, the NA sample was distinguished by worrying more about ocean pollution, attributing DA risks to climate change, expressing concerns about the potential impact of DA on future generations, and feeling better informed than the CRH group. The CRH group were more likely to attribute the DA problem to anthropogenic or industrial causes; and view the risk of health problems as lower than that associated with smoking, high cholesterol, anxiety or depression, alcoholism, high blood pressure or obesity. The CRH group was also more likely to turn to the media for DA related information. Both groups trust the decisions of state and tribe health and natural resources officials and demonstrated a complex pattern of findings that involved gender. It was recommended that risk communication and outreach activities are designed to take into consideration factors that specifically apply to each cultural community.

Factors Contributing to Mental and Physical Health Care in a Disaster-Prone Environment

Environment as a contextual factor plays an important role in southeastern Louisiana, as this area represents a major economic hub for the United States port, petroleum, and fishing industries. The location also exposes the population to both natural and technological disasters, including Hurricane Katrina and the Gulf oil spill. This study explored associations among hurricane loss, oil spill disruption, and environmental quality of life on mental and physical health on over 1,000 residents (N = 1,225) using structural equation modeling techniques. Results showed that oil spill distress was associated with increased symptoms of mental and physical health; Hurricane Katrina loss; and decreased environmental quality of life. Findings also indicate that mental health symptoms explain the association among oil spill distress and physical health symptoms-specifically, those that overlap with somatic complaints. These findings provide important support of the need for mental health assessment and service availability for disaster recovery.

Effects of exposure to oil spills on human health: Updated review

Oil spills may involve health risks for people participating in the cleanup operations and coastal inhabitants, given the toxicological properties of the oil components. In spite of this, only after a few major oil spills (crude oil or fuel oil no. 6) have studies on effects of exposure to diverse aspects of human health been performed. Previously, Aguilera et al. (2010) examined all documents published to that date dealing with any type of human health outcome in populations exposed to oil spills. The aim of the present review was to compile all new information available and determine whether evidence reported supports the existence of an association between exposure and adverse human health risks. Studies were classified in three groups according to type of health outcome addressed: (i) effects on mental health, (ii) physical/physiological effects, and (iii) genotoxic, immunotoxic, and endocrine toxicity. New studies published on oil-spill-exposed populations-coastal residents in the vicinity of the spills or participants in cleanup operations-provide additional support to previous evidence on adverse health effects related to exposure regarding different parameters in all three categories considered. Some of the observed effects even indicated that several symptoms may persist for some years after exposure. Hence, (1) health protection in these individuals should be a matter of concern; and (2) health risk assessment needs to be carried out not only at the time of exposure but also for prolong periods following exposure, to enable early detection of any potential exposure-related harmful effects.

The Third Italian Consensus Conference for Malignant Pleural Mesothelioma: State of the art and recommendations

Malignant Pleural Mesothelioma (MPM) remains a relevant public health issue, and asbestos exposure is the most relevant risk factor. The incidence has considerably and constantly increased over the past two decades in the industrialized countries and is expected to peak in 2020-2025. In Italy, a standardized-rate incidence in 2011 among men was 3.5 and 1.25 per 100,000 in men and women, respectively, and wide differences are noted among different geographic areas. The disease remains challenging in terms of diagnosis, staging and treatment and an optimal strategy has not yet been clearly defined. The Third Italian Multidisciplinary Consensus Conference on Malignant Pleural Mesothelioma was held in Bari (Italy) in January 30-31, 2015. This Consensus has provided updated recommendations on the MPM management for health institutions, clinicians and patients.

Health Risks Associated with Oil Pollution in the Niger Delta, Nigeria

Background: Although there is considerable public concern about the environmental impacts of oil pollution in the Niger Delta of Nigeria, actual evidence on the pathological and psychological effects in the health of local communities is minimally known. We sought to associate the perspective measures of exposure to oil pollution with health outcomes (inventory of health symptoms and functional capacity limitations) and determine how emotional reactions to environmental risks moderate these health outcomes. Method: The study was conducted with 600 participants selected from five local government areas in Akwa Ibom State where oil pollution is rampant. A structured questionnaire was used to collect the data on the respondents’ exposure to oil pollution, self-rated health and disease symptoms, perception of risk of exposure and emotional reactions to local oil pollution. Results: Most of the participants lived in areas with visible oil pollution and/or near gas flaring facilities and regularly suffered direct exposure to oil in their environment. High level of emotional distress was a part of everyone's life for the study population. Risk perception in the study area was mediated, to a large extent, by dreaded hazards (catastrophic fears of pipeline explosions and oil spill fire), visual cues (gas flares and smoke stacks) and chemosensory cues (off-flavor in drinking water). The exposure metrics were found to be significant predictors of the health effects and influencing factors (emotional reactions). Multi-levels models suggest that at the individual level, the demographic variables and direct contact with oil pollution were important mediators of functional capacity limitation. At the community level, emotional distress from fear of the sources of exposure was an important mediator of the health symptoms. Conclusions: This study documents high levels of disease symptoms and environmental distress (worry, annoyance and intolerance) associated with oil pollution in the Niger Delta areas of Nigeria. It highlights the need for some intervention to ameliorate the psychological distress associated with living under such environmental adversity.

Environmental exposures due to natural disasters

The environmental mobilization of contaminants by "natural disasters" is a subject of much interest, however, little has been done to address these concerns, especially in the developing world. Frequencies and predictability of events, both globally and regionally as well as the intensity, vary widely. It is clear that there are greater probabilities for mobilization of modern contaminants in sediments. Over the past 100 years of industrialization many chemicals are buried in riverine, estuarine and coastal sediments. There are a few studies, which have investigated this potential risk especially to human health. Studies that focus on extreme events need to determine the pre-existing baseline, determine the medium to long term fate and transport of contaminants and investigate aquatic and terrestrial pathways. Comprehensive studies are required to investigate the disease pathways and susceptibility for human health concerns.

Vulnerability of Coastal Communities from Storm Surge and Flood Disasters

Disasters in the form of coastal storms and hurricanes can be very destructive. Preparing for anticipated effects of such disasters can help reduce the public health and economic burden. Identifying vulnerable population groups can help prioritize resources for the most needed communities. This paper presents a quantitative framework for vulnerability measurement that incorporates both socioeconomic and flood inundation vulnerability. The approach is demonstrated for three coastal communities in Mississippi with census tracts being the study unit. The vulnerability results are illustrated as thematic maps for easy usage by planners and emergency responders to assist in prioritizing their actions to vulnerable populations during storm surge and flood disasters.

Cross-Sectional Data Within 1 Year of the Fukushima Meltdown: Effect-Size of Predictors for Depression

This cross-sectional study investigates effect sizes of depression predictors in a community close to the Fukushima, Japan nuclear reactor damaged by the 11 March, 2011 earthquake and tsunami. Subjects volunteered for assessment between December, 2011 and March, 2012. Of 466 individuals (351 female, mean age 60.4 year, SD = 14.0), 23 % of the female participants and 17 % of the male participants could be diagnosed with depression. The strongest predictors were house damage, age, income reduction, home water incursion, and casualty acquaintance. Education level, location during disaster, and workplace damage proved non-significant. The high number of retired/unemployed in the sample may have influenced outcome. Results suggest sampling influences the applicability of Conservation of Resources model to a disaster event.

Assessment of Meaning in Adolescents Receiving Clinical Services in Mississippi Following the Deepwater Horizon Oil Spill: An Application of the Purpose in Life Test-Short Form (PIL-SF)

OBJECTIVES

This study's purpose was to assess perceived meaning in adolescents. Specifically, our goals were to examine the psychometric properties of the Purpose in Life test-Short Form (PIL-SF) and its ability to predict psychological outcomes in an adolescent sample.

METHOD

Aspects of well-being (self-efficacy, life satisfaction, and resilience) and psychological distress (posttraumatic stress, depression, anxiety, and general stress) were assessed in a sample of adolescents (N = 91; 58.2% female; mean age = 14.89) receiving clinical services following the Deepwater Horizon Oil Spill.

RESULTS

Meaning was positively associated with life satisfaction, self-efficacy, and resilience, and negatively associated with posttraumatic stress and depression. Meaning was not significantly related to anxiety or general stress. Females reported significantly more meaning than males, while no significant differences were noted by race/ethnicity.

CONCLUSIONS

The PIL-SF is a useful measure with adolescents. Moreover, meaning is an important concept to consider with respect to disasters.

Ethical Issues in Environmental Health Research Related to Public Health Emergencies: Reflections on the GuLF STUDY

Health research in the context of an environmental disaster with implications for public health raises challenging ethical issues. This article explores ethical issues that arose in the Gulf Long-term Follow-up Study (GuLF STUDY) and provides guidance for future research. Ethical issues encountered by GuLF STUDY investigators included a ) minimizing risks and promoting benefits to participants, b ) obtaining valid informed consent, c ) providing financial compensation to participants, d ) working with vulnerable participants, e ) protecting participant confidentiality, f ) addressing conflicts of interest, g ) dealing with legal implications of research, and h ) obtaining expeditious review from the institutional review board (IRB), community groups, and other committees. To ensure that ethical issues are handled properly, it is important for investigators to work closely with IRBs during the development and implementation of research and to consult with groups representing the community. Researchers should consider developing protocols, consent forms, survey instruments, and other documents prior to the advent of a public health emergency to allow for adequate and timely review by constituents. When an emergency arises, these materials can be quickly modified to take into account unique circumstances and implementation details.

Psychological Vulnerability of Residents of Communities Affected by the Hebei Spirit Oil Spill

OBJECTIVE

Psychological health is an important issue after disasters. This study aimed to investigate the prevalence of psychological symptoms among 993 residents of Taean District in South Korea after the Hebei Spirit oil spill and to examine determinants of vulnerability in residents' psychological symptoms.

METHODS

Symptoms of post-traumatic stress (PTS), depression, suicidal ideation, and anxiety were assessed by questionnaires, and the responses were analyzed by using the survey analysis considering the sampling frame.

RESULTS

Among the study subjects, the symptom prevalences of PTS, depression, suicidal ideation, and anxiety were 19.5%, 22.0%, 2.3%, and 4.2%, respectively, and symptoms were higher in people who were female, were older, were less educated, and had lower family income. People with fishery or related occupations compared to those with unrelated livelihoods and people residing in the vicinity of the oil band in the contaminated coastline showed additively increased symptom risks of PTS. Risk of suicidal ideation was predominantly increased in people with fishery or related occupations compared with those with unrelated livelihoods.

CONCLUSIONS

Social supports, including compensation for income loss and community mental health programs, and longer follow-up studies are needed for residents in the communities affected by the Hebei Spirit oil spill.

Compensation and Community Corrosion: Perceived Inequalities, Social Comparisons, and Competition Following the Deepwater Horizon Oil Spill

After disasters, victim compensation programs are typically associated with individual healing and community rebuilding. But post-disaster compensation systems also have the potential to introduce confusion and competition, further fraying the social fabric of communities affected by trauma. To assess the perceived effects of disaster compensation processes on community social relations, as well as the mechanisms that underlie such effects, we turn to the case of the Deepwater Horizon oil spill, after which BP implemented one of the largest compensation systems in U.S.

HISTORY

Using data from interviews of residents of four Gulf Coast communities, we examine the extent to which this claims process hindered efforts to recover from this disaster. Our data suggest that while BP money helped some residents in the Gulf during a difficult economic time, many interviewees perceived uncertainty, randomness, and unevenness in the compensation process, which led to negative social comparisons and competition among community members. Because of this animosity, we argue that BP's compensation system was a disruptive mechanism that contributed to community corrosion and introduced another source of psychological stress into already traumatized areas.

The resilience activation framework: a conceptual model of how access to social resources promotes adaptation and rapid recovery in post-disaster settings

A number of governmental agencies have called for enhancing citizens' resilience as a means of preparing populations in advance of disasters, and as a counterbalance to social and individual vulnerabilities. This increasing scholarly, policy, and programmatic interest in promoting individual and communal resilience presents a challenge to the research and practice communities: to develop a translational framework that can accommodate multidisciplinary scientific perspectives into a single, applied model. The Resilience Activation Framework provides a basis for testing how access to social resources, such as formal and informal social support and help, promotes positive adaptation or reduced psychopathology among individuals and communities exposed to the acute collective stressors associated with disasters, whether human-made, natural, or technological in origin. Articulating the mechanisms by which access to social resources activate and sustain resilience capacities for optimal mental health outcomes post-disaster can lead to the development of effective preventive and early intervention programs.

Mental health consequences of chemical and radiologic emergencies: a systematic review

This article reviews the literature pertaining to psychological impacts in the aftermath of technological disasters, focusing on the immediate psychological and mental health consequences emergency department physicians and first responders may encounter in the aftermath of such disasters. First receivers see a wide spectrum of psychological distress, including acute onset of psychiatric disorders, the exacerbation of existing psychological and psychiatric conditions, and widespread symptomatology even in the absence of a diagnosable disorder. The informal community support systems that exist after a natural disaster may not be available to communities affected by a technological disaster leading to a need for more formal mental health supportive services.

Psychological responses and resilience of people and communities impacted by the deepwater horizon oil spill

On April 20, 2010, the BP Deepwater Horizon oil platform in the United States Gulf of Mexico exploded, killing 11 persons and resulting in a 5-month spill of more than 206 million gallons of oil, affecting more than 950 miles of shoreline. Our initial studies in Baldwin County, Alabama, and Franklin County, Florida, conducted while the oil spill was still in progress, showed high levels of clinically significant anxiety and depression in persons living in coastal communities. Income loss was the most significant driver of anxiety and depression, rather than direct influx or contact with oil. Ongoing studies of these groups and their communities have been conducted under the auspices of the National Institute of Environmental Health Sciences (NIEHS) Deepwater Horizon Research Consortium. A year after the spill, there was no significant change in levels of anxiety or depression in our cohort. Income loss continued to be associated with higher levels of psychopathology; findings were not associated with age, gender, education, or psychiatric history. Media exposure was associated with persistent hyperarousal. Findings support a model of chronic psychological disruption after the oil spill disaster. Community studies underscored the "corrosive" nature of this type of man-made disaster (as compared with natural disasters that have hit the region), with particular concerns expressed about the compensation process administered by British Petroleum and the parties that followed. Our research highlights the very real and long-lasting impact of such disasters on individuals and communities, extending well beyond the areas where there was direct exposure to oil.

Children's Mental Health in the Area Affected by the Hebei Spirit Oil Spill Accident

OBJECTIVES

Children are one of the most vulnerable populations to the impact of disasters. We aimed to examine children's mental health in the area affected by the Hebei Spirit oil spill accident on December 7, 2007.

METHODS

A cross-sectional questionnaire survey was conducted using the Korean versions of the Children's Depression Inventory and State Anxiety Inventory for Children on 1,362 children attending elementary schools in the affected area. The information on distances between the nearest contaminated coastline to the child's residential house or attending school were obtained using a web-based map by inputting two address points. The symptom risks of depression and state anxiety were estimated by multiple logistic regression analyses adjusted for age, gender, and other covariates.

RESULTS

Children with the closest distance (in the fourth quartile) to the school from the contaminated coastline showed a significantly higher symptom risk of depression compared to those with the farthest distance (first quartile)(odds ratio, 2.73; 95% confidence interval, 1.40-5.33), while there was no significant association between anxiety symptoms and distance.

CONCLUSIONS

Children, a vulnerable population for mental health impact by the oil spill accident, should be included in mental health programs in the community along with their family as victims of the disaster.

Public perceptions of the response to the Deepwater Horizon oil spill: personal experiences, information sources, and social context

The 2010 British Petroleum (BP) Deepwater Horizon oil spill highlighted long-standing questions about energy exploration and its social and environmental implications. Sociologists studying environmental disasters have documented the social impacts resulting from these events and dissatisfaction with government and industry responses. In this paper, we use data from a survey conducted during the Gulf of Mexico oil spill to examine how Louisiana and Florida residents' social backgrounds, experiences with the spill, and trust in information sources predict their perceptions of governmental and BP response efforts. We find that direct personal impacts and compensation strongly influence the evaluations of responding organizations. Age and place of residence also predict such assessments. Finally, levels of confidence in television news and BP as sources of information appear to shape Gulf Coast residents' opinions about the work of organizations responding to the Deepwater Horizon disaster.

RNA-Seq reveals complex genetic response to Deepwater Horizon oil release in Fundulus grandis

Background

The release of oil resulting from the blowout of the Deepwater Horizon (DH) drilling platform was one of the largest in history discharging more than 189 million gallons of oil and subject to widespread application of oil dispersants. This event impacted a wide range of ecological habitats with a complex mix of pollutants whose biological impact is still not yet fully understood. To better understand the effects on a vertebrate genome, we studied gene expression in the salt marsh minnow Fundulus grandis, which is local to the northern coast of the Gulf of Mexico and is a sister species of the ecotoxicological model Fundulus heteroclitus. To assess genomic changes, we quantified mRNA expression using high throughput sequencing technologies (RNA-Seq) in F. grandis populations in the marshes and estuaries impacted by DH oil release. This application of RNA-Seq to a non-model, wild, and ecologically significant organism is an important evaluation of the technology to quickly assess similar events in the future.

Results

Our de novo assembly of RNA-Seq data produced a large set of sequences which included many duplicates and fragments. In many cases several of these could be associated with a common reference sequence using blast to query a reference database. This reduced the set of significant genes to 1,070 down-regulated and 1,251 up-regulated genes. These genes indicate a broad and complex genomic response to DH oil exposure including the expected AHR-mediated response and CYP genes. In addition a response to hypoxic conditions and an immune response are also indicated. Several genes in the choriogenin family were down-regulated in the exposed group; a response that is consistent with AH exposure. These analyses are in agreement with oligonucleotide-based microarray analyses, and describe only a subset of significant genes with aberrant regulation in the exposed set.

Conclusion

RNA-Seq may be successfully applied to feral and extremely polymorphic organisms that do not have an underlying genome sequence assembly to address timely environmental problems. Additionally, the observed changes in a large set of transcript expression levels are indicative of a complex response to the varied petroleum components to which the fish were exposed.

UNNECESSARILY NEGLECTED IN PLANNING: ILLUSTRATION OF A PRACTICAL APPROACH TO IDENTIFY HUMAN DIMENSION IMPACTS OF MARINE OIL SPILLS

Technological hazards research, including that on oil spills and their aftermath, is giving greater attention to human dimension impacts resulting from events and response. While oil spill contingency planners recognize the importance of human dimension impacts, little systematic attention is given to them in contingency plans. We introduce an approach to identifying human dimensions impacts using concepts from hazard and vulnerability assessment and apply it to the Bouchard-120 oil spill in Buzzards Bay, MA. Our assessment covers the spill, emergency response, clean-up, damage assessment, and mid-term recovery. This approach, while still exploratory, did demonstrate that the spill produced a range of positive and negative impacts on people and institutions and that these were mediated by vulnerabilities. We suggest ways in which the framework may help spill managers to learn from events and improve contingency planning by anticipating risks to social systems and identifying strategies to reduce impacts.

Responses of microbial community from northern Gulf of Mexico sandy sediments following exposure to Deepwater Horizon crude oil

In the present study, microbial community responses to exposure to unweathered Macondo Well crude oil and conventional diesel in a sandy beach environment were determined. Biodegradation was assessed in mesocosm experiments with differing fuel amounts (2,000 and 4,000 mg/kg) and with or without inorganic nutrient amendment. Carbon dioxide production was measured daily for 42 d. Aerobic alkane, total hydrocarbon, and polycyclic aromatic hydrocarbon (PAH) degraders were enumerated in treated and control mesocosms and changes in their abundances were measured weekly. Hydrocarbon mineralization occurred in all treatments. In the inorganic nutrient-amended treatments, the degradation rates were 2.31 and 2.00 times greater in the 2,000 mg/kg diesel and crude oil treatments, respectively, and 3.52 (diesel) and 4.14 (crude) times higher for the fuel types at the 4,000 mg/kg fuel concentrations compared to unamended treatments. Microbial lag phases were short (<3 d) and alkane and total hydrocarbon degrader numbers increased by five orders of magnitude compared to the uncontaminated treatments within 7 d in most treatments. Hydrocarbon degrader numbers in diesel and in crude oil treatments were similar; however, the PAH degraders were more abundant in the crude oil relative to diesel treatment. These findings indicate that hydrocarbon degradation by extant microbial populations in the northern Gulf of Mexico sandy beach environments can be stimulated and enhanced by inorganic nutrient addition.
