Adverse Effects of the Deepwater Horizon oil spill Amid Cumulative Disasters: A Qualitative Analysis of the Experiences of Children and Families.

Limited research has examined the ramifications of the Deepwater Horizon oil spill (DHOS) on children and their families. This study builds on secondary data analysis and representative survey findings from the multi-method, multi-phase Gulf Coast Population Impact (GCPI) project. Specifically, this phase of the GCPI research draws on in-depth, semi-structured interview and focus group data to illuminate the social conditions that influenced poor child health outcomes in the aftermath of the DHOS and amid other disasters. These qualitative data were collected two years after the spill with caregivers, teachers, faith- and community-based leaders in five highly impacted Gulf Coast communities. Exploratory qualitative analysis revealed that children were affected by the DHOS and other related challenges through exposure to familial stress emerging from livelihood disruptions. Such disruptions were the result of ongoing poverty, damage to the fishing industry, and exposure to cumulative and compounding environmental disasters. In cases of severe familial stress, children may have experienced toxic stress because of caregivers' displaced distress; ambiguous loss through caregivers' physical and/or emotional absence; and the children's recognition of their families' dire financial situations. Toxic stress was most often expressed through acute and chronic physiological, emotional, and behavioral health challenges. This study expands current understandings of the impact of technological disasters and cumulative environmental disasters on children and families. It underscores the importance of investing in harm prevention strategies to reduce threats to the health and wellbeing of young people living in ecologically and socioeconomically insecure environments prone to intensifying technological and climate-fueled disasters.

Indoor Temperature and Energy Insecurity: Implications for Prenatal Health Disparities in Extreme Heat Events.

BACKGROUND: Extreme heat events are a major public health concern and are only expected to increase in intensity and severity as climate change continues to accelerate. Pregnant people are physiologically more vulnerable to the effects of extreme heat, and exposure can induce harm on both the pregnant person and the fetus. OBJECTIVES: This commentary argues that there is a need for greater epidemiological research on indoor heat exposure and energy insecurity as potential drivers of maternal and child environmental health disparities. DISCUSSION: While there is substantial evidence linking ambient (outdoor) high temperature to pregnancy-related outcomes, there is a lack of epidemiological evidence to date on pregnant people's exposure to high indoor temperature and adverse maternal and/or child health outcomes. Energy insecurity is disproportionately experienced by people with low incomes and/or people of color, and indoor temperature may play a role in shaping socioeconomic and racial/ethnic disparities in maternal and child health in the United States. Further research is needed to understand the relationship between indoor heat exposure, energy insecurity, and pregnancy outcomes in both parents and children and to inform potential policies and practices to enhance resilience and reduce maternal/child health disparities. https://doi.org/10.1289/EHP13706.

Associations Between COVID-19 Vaccine Hesitancy and Socio-Spatial Factors in NYC Transit Workers 50 Years and Older.

This analysis investigates how age, race/ethnicity, and geographic location contributed to vaccine hesitancy in a sample of 645 New York City (NYC) Transport Workers Union (TWU), Local 100 members surveyed in August 2020. Union members ages 50+ were 46% less likely to be vaccine hesitant than their younger counterparts (OR 0.64; 95% CI 0.42, 0.97). Non-Whites (OR 3.95; 95% 2.44, 6.39) and those who did not report their race (OR 3.10; 95% CI 1.87, 5.12) were significantly more likely to be vaccine hesitant than Whites. Those who were not concerned about contracting COVID-19 in the community had 1.83 greater odds (95% CI 1.12, 2.98) of being vaccine hesitant than those who were concerned. Older respondents tended to reside in Queens while vaccine hesitant and non-White respondents were clustered in Brooklyn. General trends observed in COVID-19 vaccine hesitancy persist in a population of high risk, non-healthcare essential workers.

Examining the effects of cumulative environmental stressors on Gulf Coast child and adolescent health.

This study examines how community-level cumulative environmental stress affects child and adolescent emotional distress and chronic health conditions both directly and indirectly through stressors at the household, family, and individual levels. Data comes from the Women and their Children's Health (WaTCH) Study, which sought to understand the health implications of exposure to the 2010 Deepwater Horizon oil spill (DHOS) among a cohort of 596 mothers with children ages 10 to 17 in southeastern Louisiana. Community-level environmental stress was measured using a newly developed geospatial index. Household-level stressors included previous hurricane impacts, impacts of DHOS, degree of financial difficulty, and degree of housing physical decay. Family stressors included maternal depression, self-rated physical health, and degree of parenting stress. Child stress was based on perceived stress; child mental health was based on serious emotional disturbance; and child physical health was based on diagnosis of chronic illness. Structural equation modeling used weighted least squares means and variance and theta parameterization. Results showed a significant negative direct path between community-level cumulative environmental stress and child/adolescent serious emotional disturbance and chronic illness. However, the indirect relationship through household, family, and individual-level stressors was significant and positive for both child/adolescent serious emotional disturbance and chronic illness. These findings point to the centrality of the household and family in determining child and adolescent physical and mental health outcomes in communities exposed to frequent disasters and ongoing environmental stressors.

Anti-Vaccine Attitudes among Adults in the U.S. during the COVID-19 Pandemic after Vaccine Rollout.

Even though vaccination is the most effective measure against COVID-19 infections, vaccine rollout efforts have been hampered by growing anti-vaccine attitudes. Based on current knowledge, we identified three domains (beliefs, discrimination, and news) as our correlates of primary interest to examine the association with anti-vaccine attitudes. This is one of the first studies to examine key correlates of anti-vaccine attitudes during the critical early stages of vaccine implementation in the United States. An online survey was administered in May 2021 to a non-representative, nationally based sample of adults (N = 789). Using multivariable logistic regression analysis, we found that individuals who expressed worry about COVID-19 (OR = 0.34, 95% CI 0.21, 0.55) and had greater knowledge of COVID-19 (OR = 0.50, 95% CI 0.25, 0.99) were less likely to hold anti-vaccine attitudes. Conversely, individuals who held stigmatizing views of COVID-19 (OR = 2.47, 95% CI 1.53, 3.99), had experienced racial discrimination (OR = 2.14, 95% CI 1.25, 3.67) and discrimination related to COVID-19 (OR = 2.84, 95% CI 1.54, 5.24), and who had been watching Fox News (OR = 3.95, 95% CI 2.61, 5.97) were more likely to hold anti-vaccine attitudes. These findings suggest COVID-19 beliefs, experiences of discrimination, and news sources should be considered when designing targeted approaches to address the anti-vaccine movement.

The Chemistry and Health Outcomes of Electronic Waste (E-Waste) Leachate: Exposure to E-Waste Is Toxic to Atlantic Killifish (Fundulus heteroclitus) Embryos.

Although there is rising global concern over the environmental, ecological, and human health risks associated with the discharge of leachates from e-waste dumpsites into the aquatic ecosystems, little is known in this research area. Thus, for this study, we first defined the chemistry of the test leachate, followed by assessment of the leachate on the development of a model aquatic organism (Fundulus heteroclitus) used extensively as a bioassay organism in pollution studies. Chemical analyses revealed that levels of phosphate (20.03 mg/L), cadmium (Cd) (0.4 mg/L), lead (Pb) (0.2 mg/L), and chromium (Cr) (0.4 mg/L) were higher than the 2009 US EPA and the 2009 National Environmental Standards and Regulations Enforcement Agency (NESREA) permissible limits. Polycyclic aromatic hydrocarbon (PAH) burdens were dominated mainly by the high molecular weight congeners, specifically the ∑4rings (73 µg/L). Total polychlorinated biphenyls (PCB) levels ranged from 0.00 to 0.40 µg/L with the ∑deca PCBs reaching the highest concentration. For the biological studies, F. heteroclitus embryos (48-h post-fertilization) were divided randomly into groups and exposed to one of six e-waste leachate concentrations (10, 1, 0.1, 0.01, 0.001, 0.0001%). Significant differences (p ≤ 0.05) between treated and control groups were observed in standard and total length, and head size. Further analysis using Duncan's post-hoc test of multiple comparison also revealed specific differences within and between specific treatment groups. We conclude that e-waste leachate arising from indiscriminate dumping into aquatic ecosystems in Nigeria contains mixtures of toxic constituents that can threaten ecosystem and public health.

Behavioral Correlates of COVID-19 Worry: Stigma, Knowledge, and News Source.

Non-adherence to COVID-19 guidelines may be attributable to low levels of worry. This study assessed whether endorsing COVID-19-stigmatizing restrictions, COVID-19 knowledge, and preferred news source were associated with being 'very worried' versus 'not at all' or 'somewhat' worried about contracting COVID-19. Survey data were collected in July-August 2020 from N = 547 New York State (NYS) and N = 504 national Amazon MTurk workers. Respondents who endorsed COVID-19 stigmatizing restrictions (NYS OR 1.96; 95% CI 1.31, 2.92; national OR 1.80; 95% CI 1.06, 3.08) and consumed commercial news (NYS OR 1.89; 95% CI 1.21, 2.96; national OR 1.93; 95% CI 1.24, 3.00) were more likely to be very worried. National respondents who consumed The New York Times (OR 1.52; 95% CI 1.00, 2.29) were more likely to be very worried, while those with little knowledge (OR 0.24; 95% CI 0.13, 0.43) were less likely to be very worried. NYS (OR 2.66; 95% CI 1.77, 4.00) and national (OR 3.17; 95% CI 1.95, 5.16) respondents with probable depression were also more likely to be very worried. These characteristics can help identify those requiring intervention to maximize perceived threat to COVID-19 and encourage uptake of protective behaviors while protecting psychological wellbeing.

A contemporary review of electronic waste through the lens of inhalation toxicology.

Inhalation is a significant route of exposure to toxic chemicals for electronic waste (e-waste) workers, especially for those whose activities take place in the informal sector. However, there remains a dearth of research on the health effects produced by the hazardous dismantling of e-waste and associated outcomes and biological mechanisms that occur as a result of inhalation exposure. This contemporary review highlights a number of the toxicological and epidemiological studies published on this topic to bring to light the many knowledge gaps that require further research, including in vitro and ex vivo investigations to address the health outcomes and underlying mechanisms of inhaled e-waste-associated pulmonary disease.

The effects of cumulative natural disaster exposure on adolescent psychological distress.

Natural disasters are becoming more frequent and destructive due to climate change and have been shown to be associated with a variety of adverse mental health outcomes in children and adolescents. This study utilizes data from three cohort studies of Hurricane Katrina survivors-including low-income mothers from New Orleans; displaced and highly impacted families from Louisiana and Mississippi; and Vietnamese immigrants in New Orleans-to examine the relationship between cumulative natural disaster exposure and adolescent psychological distress approximately 13 years after Katrina. Among 648 respondents with children ages 10-17, 112 (17.2%) reported that their child had exhibited one or more symptoms of psychological distress in the past month. Overall, respondents had experienced an average of 0.6 (SD 1.0) natural disasters following Hurricane Katrina. Each additional natural disaster experienced by the respondent was associated with 1.41 (95% CI 1.05, 1.88) greater odds of his or child experiencing psychological distress in the past month. This relationship was not significantly moderated by any measures of family resilience or vulnerability, nor by race/ethnicity or socioeconomic status, although family functioning, parental coping, and caregiver mental health were independently associated with adolescent psychological distress. The results of this analysis suggest that natural disasters have cumulative, detrimental impacts on adolescent mental health.

Particulate Matter and Associated Metals: A Link with Neurotoxicity and Mental Health.

Particulate air pollution (PM) is a mixture of heterogenous components from natural and anthropogenic sources and contributes to a variety of serious illnesses, including neurological and behavioral effects, as well as millions of premature deaths. Ultrafine (PM0.1) and fine-size ambient particles (PM2.5) can enter the circulatory system and cross the blood-brain barrier or enter through the optic nerve, and then upregulate inflammatory markers and increase reactive oxygen species (ROS) in the brain. Toxic and neurotoxic metals such as manganese (Mn), zinc (Zn), lead (Pb), copper (Cu), nickel (Ni), and barium (Ba) can adsorb to the PM surface and potentially contribute to the neurotoxic effects associated with PM exposure. Epidemiological studies have shown a negative relationship between exposure to PM-associated Mn and neurodevelopment amongst children, as well as impaired dexterity in the elderly. Inhaled PM-associated Cu has also been shown to impair motor performance and alter basal ganglia in schoolchildren. This paper provides a brief review of the epidemiological and toxicological studies published over the last five years concerning inhaled PM, PM-relevant metals, neurobiology, and mental health outcomes. Given the growing interest in mental health and the fact that 91% of the world's population is considered to be exposed to unhealthy air, more research on PM and PM-associated metals and neurological health is needed for future policy decisions and strategic interventions to prevent public harm.

Impact of occupational exposure to COVID-19 on the physical and mental health of an essential workgroup: New York City transit workers.

Background and purpose: Early on in the COVID-19 pandemic, New York City (NYC) vowed to "keep the subways running" despite the lack of plans in place for protecting the health and well-being of transit workers. This study was designed to assess the impact of employment during the early phase of the pandemic on this essential frontline workforce. Methods, settings, and study participants: A convenience sample of members (stratified by job title) of the NYC Transport Workers Union, Local 100, was recruited in August 2020 to participate in an anonymous, cross-sectional, internet-based survey. Results: The demographics of the sample participants (N = 645) reflected union membership, ie, 82 percent male, 29 percent Black; 27 percent Hispanic, and 59 percent ≥age 50 years. At the time of the "NYC Pause" (March 22, 2020) when mandatory stay-at-home orders were issued, transit workers had limited worksite protections. Many reported a lack of such basics as face masks (43 percent), hand sanitizer (40 percent), and disposable gloves (34 percent). A high proportion (87 percent) were concerned about getting infected at work. Lack of certain protections was significantly associated with both fear of contagion at work and mental health symptoms. Nearly 24 per­cent of participants reported a history of COVID-19 infection. Self-reported infection was significantly correlated with lack of certain protections, including respiratory masks (p < 0.001), disposable gloves (p < 0.001), and hand sanitizer (p < 0.001). Infection was also significantly associated with mental health symptoms (p < 0.001). By August 2020, despite participants reporting that many worksite protections were then in place, 72 percent of workers were still fearful for their safety at work, eg, because of potential exposure due to passengers not wearing masks, and risk of verbal abuse and physical assault by passengers angered when asked to wear face masks. Workers who were fearful for their safety at work were more than six times more likely to report mental health symptoms (p < 0.001). Conclusions: Lack of worksite protections before "NYC Pause" (March 22, 2020) was significantly associated with self-reported infection, fear, and mental health symptoms in TWU, Local 100 members. To reduce the risk of adverse impacts associated with bioevents in all essential work groups, and across all essential occupational settings, infection control preparedness, early recognition of risk, and implementation of tailored risk reduction strategies are imperative. Pandemic preparedness is fundamental to protecting the health and well-being of essential workers and crucial in controlling the spread of disease in the community. Bioevent preparedness for all essential frontline workgroups will also help reduce occupational health inequities. Workers at risk, regardless of setting, deserve and have the right to equal protections under federal and state law.

A Systematic Review of Environmental Health Outcomes in Selected American Indian and Alaska Native Populations.

BACKGROUND: Economic and social marginalization among American Indians and Alaska Natives (AI/ANs) results in higher chronic disease prevalence. Potential causal associations between toxic environmental exposures and adverse health outcomes within AI/AN communities are not well understood. OBJECTIVES: This review examines epidemiological literature on exposure to toxicants and associated adverse health outcomes among AI/AN populations. METHODS: PubMed, Embase, Cochrane, Environment Complete, Web of Science Plus, DART, and ToxLine were searched for English-language articles. The following data were extracted: lead author's last name, publication year, cohort name, study location, AI/AN tribe, study initiation and conclusion, sample size, primary characteristic, environmental exposure, health outcomes, risk estimates, and covariates. RESULTS: About 31 articles on three types of environmental exposures met inclusion criteria: persistent organic pollutants (POPs), heavy metals, and open dumpsites. Of these, 17 addressed exposure to POPs, 10 heavy metal exposure, 2 exposure to both POPs and heavy metals, and 2 exposure to open dumpsites. Studies on the Mohawk Nation at Akwesasne; Yupik on St. Lawrence Island, Alaska; Navajo Nation; Gila River Indian Community; Cheyenne River Sioux; 197 Alaska Native villages; and 13 tribes in Arizona, Oklahoma, North Dakota, and South Dakota that participated in the Strong Heart Study support associations between toxicant exposure and various chronic conditions including cardiovascular conditions, reproductive abnormalities, cancer, autoimmune disorders, neurological deficits, and diabetes. DISCUSSION: The complex interplay of environmental and social factors in disease etiology among AI/ANs is a product of externally imposed environmental exposures, systemic discrimination, and modifiable risk behaviors. The connection between environmental health disparities and adverse health outcomes indicates a need for further study.
