Environmental Justice and Systems Analysis for Air Quality Planning in the Port of Oakland in California.

Many frontline communities experience adverse health impacts from living in proximity to high-polluting industrial sources. Securing environmental justice requires, in part, a comprehensive set of quantitative indicators. We incorporate environmental justice and life-cycle thinking into air quality planning to assess fine particulate matter (PM2.5) exposure and monetized damages from operating and maintaining the Port of Oakland, a major multimodal marine port located in the historically marginalized West Oakland community in the San Francisco Bay Area. The exposure domain for the assessment is the entire San Francisco Bay Area, a home to more than 7.5 million people. Of the more than 14 sources included in the emissions inventory, emissions from large container ships, or ocean-going vessels (OGVs), dominate the PM2.5 intake, and supply chain sources (material production and delivery, fuel production) represent between 3.5% and 7.5% of annual intake. Exposure damages, which model the costs from excess mortalities resulting from exposure from the study's emission sources, range from USD 100 to 270 million per annum. Variations in damages are due to the use of different concentration-response relationships, hazard ratios, and Port resurfacing area assumptions. Racial and income-based exposure disparities are stark. The Black population and people within the lowest income quintile are 2.2 and 1.9 times more disproportionately exposed, respectively, to the Port's pollution sources relative to the general population. Mitigation efforts focused on electrifying in-port trucking operations yield modest reductions (3.5%) compared to strategies that prioritize emission reductions from OGVs and commercial harbor craft operations (8.7-55%). Our recommendations emphasize that a systems-based approach is critical for identifying all relevant emission sources and mitigation strategies for improving equity in civil infrastructure systems.

An Interactive Mapping and Case Discussion Seminar Introducing Medical Students to Climate Change, Environmental Justice, and Health.

Introduction: Integrating climate change and health into a medical school curriculum is critical for future physicians who will manage health crises caused by a rapidly changing climate. Although medical schools have increasingly included climate change in the curriculum, there remains a need to address the link between the climate crisis, environmental justice, and historical policies that shape environmental health disparities in local communities. Methods: In academic years 2021-2022 (AY22) and 2022-2023 (AY23), second-year medical students participated in a 2.5-hour seminar utilizing didactic teaching and small breakout groups that included interactive mapping activities and case scenarios. Learner knowledge and attitudes were self-assessed using pre- and postcurriculum surveys and a quiz. Qualitative thematic and content analysis was used to evaluate short-answer quiz responses and feedback. Results: Of 357 students who participated in the seminar, 208 (58%) completed both the precurriculum and postcurriculum surveys. Self-assessed ability increased significantly for all educational objectives across both years. Attitudes on the importance of climate change knowledge for patient health also improved from a mean of 3.5 precurriculum to 4.2 postcurriculum (difference = 0.7, p < .01) in AY22 and from 3.6 pre- to 4.3 postcurriculum (difference = 0.7, p < .01) in AY23 on a 5-point Likert scale. Discussion: This climate change and health session highlighting the link between environmental policy and climate change health vulnerability in the local context was successful in improving students' self-assessed ability across all stated educational objectives. Students cited the interactive small-group sessions as a major strength.

[A top-down path to promote environmental justice in a contaminated area. The experience with the community of Porto Torres (Sardinia, Italy)]. / Un percorso top-down di promozione della giustizia ambientale in un sito contaminato. L'esperienza con la comunità di Porto Torres.

Nowadays, in Italy, researchers from various disciplines and institutions are referring to environmental justice to promote health equity in relation to environmental risks and benefits. This presents an opportunity for the convergence of bottom-up and top-down perspectives, which differ in nature, to advance environmental justice at the local level. This contribution presents the experience of researchers from the Italian National Institute of Health in the contaminated area of Porto Torres (Sardinia). The experience began with the development of study activities aimed at describing the health profile of the population residing in Porto Torres. These activities embraced the requests of the local community and included interactions with local institutional and social actors. The study activities were designed with a focus on environmental justice, which requires an understanding of the local context and of its history. The contribution describes the various stages that led from the development of the study to the engagement with local institutional and social actors, communication of study results, and participation in local initiatives on environmental justice. Finally, the text proposes some considerations on how researchers from a central institution can develop and conduct study activities to promote environmental justice at the local level.

Forest, climate, and policy literature lacks acknowledgement of environmental justice, diversity, equity, and inclusion.

Forests boast essential resources and potential to mitigate climate change, meriting the development of conservation policies on all governmental scales. Ecosystem services provided by forests, including biodiversity, air quality, and food and fuel production, make forests valuable assets for climate-vulnerable communities that often lack the means to cope with ecosystem service degradation resulting from climate change. Historically, these vulnerable communities are previously marginalized and socio-economically limited, and climate change augments already-existing injustices. Policy discussions around managing forests and carbon, therefore, must consider environmental justice as well as diversity, equity, and inclusion to better meet the needs of all constituents. Using R, we perform a review of forest, climate, and policy peer-reviewed literature published between 2018 and 2021 for prevalence of topics related to diversity, equity, inclusion, and justice (DEIJ). We select DEIJ terms a priori and a posteriori based on our understanding of DEIJ and common considerations of the literature. Out of 2891 unique articles, 15.7% of literature mentioned at least one DEIJ term in the title, keyword list, or abstract. We identify which journals have published DEIJ literature more often in the context of forest, climate, and policy, and we perform a co-occurrence analysis of additional common themes. Concepts such as ecosystem services and economics appeared often in the literature, as well as REDD+ as a specifically mentioned policy. We call for increased consideration of DEIJ in forest, climate, and policy discussions and literature, as vulnerable communities historically have been excluded from and victimized by the conversations held among large, economically motivated entities.

Unpacking Neighborhood Socioeconomic Status in Children's Health Research from an Environmental Justice Perspective: A Scoping Review.

PURPOSE OF REVIEW: Clearly defining and measuring neighborhood socioeconomic status (nSES) is a key first step in achieving environmental justice, as the disproportionate distribution of environmental hazards and access to resources is heavily influenced by socioeconomic factors. This scoping review explores the definition of neighborhoods, measurement of neighborhood socioeconomic status (nSES), and studies that evaluated the association between nSES and child health in accordance with PRISMA guidelines. RECENT FINDINGS: We identified 4112 articles published on US pediatric populations between 2013 and 2022. We identified 170 distinct indicators across seven broad domains of nSES used to create 121 different measures of nSES across the 206 publications included in this review. While there is considerable interest in nSES and children's health, there is also substantial variation in the measurement of neighborhood as a geographic unit and nSES as a construct. We observed methodological challenges related to the identification of neighborhood boundaries, indicator selection, and nSES measure definition(s). We discuss common pitfalls in neighborhood research that can complicate identifying, targeting, and resolving environmental injustices. Lastly, we put forward a series of recommendations to reduce measurement error and improve inference, in addition to reporting recommendations for neighborhoods and health research that can aid in improving our understanding of pathways between neighborhood context and child health, inform policy development, and allocate resources to achieve environmental justice.

Assessing the 2023 Canadian wildfire smoke impact in Northeastern US: Air quality, exposure and environmental justice.

The Canadian wildfires in June 2023 significantly impacted the northeastern United States, particularly in terms of worsened air pollution and environmental justice concerns. While advancements have been made in low-cost sensor deployments and satellite observations of atmospheric composition, integrating dynamic human mobility with wildfire PM2.5 exposure to fully understand the environmental justice implications remains underinvestigated. This study aims to enhance the accuracy of estimating ground-level fine particulate matter (PM2.5) concentrations by fusing chemical transport model outputs with empirical observations, estimating exposures using human mobility data, and evaluating the impact of environmental justice. Employing a novel data fusion technique, the study combines the Weather Research and Forecasting model with Chemistry (WRF-Chem) outputs and surface PM2.5 measurements, providing a more accurate estimation of PM2.5 distribution. The study addresses the gap in traditional exposure assessments by incorporating human mobility data and further investigates the spatial correlation of PM2.5 levels with various environmental and demographic factors from the US Environmental Protection Agency (EPA) Environmental Justice Screening and Mapping Tool (EJScreen). Results reveal that despite reduced mobility during high PM2.5 levels from wildfire smoke, exposure for both residents and individuals on the move remains high. Regions already burdened with high environmental pollution levels face amplified PM2.5 effects from wildfire smoke. Furthermore, we observed mixed correlations between PM2.5 concentrations and various demographic and socioeconomic factors, indicating complex exposure patterns across communities. Urban areas, in particular, experience persistent high exposure, while significant correlations in rural areas with EJScreen factors highlight the unique vulnerabilities of these populations to smoke exposure. These results advocate for a comprehensive approach to environmental health that leverages advanced models, integrates human mobility data, and addresses socio-demographic disparities, contributing to the development of equitable strategies against the growing threat of wildfires.

Examining the impact of air pollution, climate change, and social determinants of health on asthma and environmental justice.

PURPOSE OF REVIEW: In this review, we discuss the current literature examining the impact air pollution and climate change has on asthma onset, control, and exacerbation. This review also addresses the risk of exposure to specific disproportionately affected communities, highlighting health disparities in exposure and asthma outcomes. RECENT FINDINGS: Recent studies have shifted from highlighting the associations between asthma exacerbations and indoor and outdoor air pollution. Studies are now focused on confirming the association of asthma incidence from these same exposures. Many studies have linked particulate matter to adverse asthma outcomes, however, the pollutant exposures that pose the greatest risk and the effect of natural disasters fueled by climate change are under current study. Some studies have observed that the true burden that pollutant exposures have on asthma outcomes occurs at the intersection of exposure and vulnerability. Future studies in this area will address social determinants of health, societal factors such as redlining and other systemic racism practices. SUMMARY: Although decades of research support the causal link between gaseous and particulate air pollution and the exacerbation of preexisting asthma, recent studies suggest air pollution can cause incident (new onset) asthma. Studies have started to focus on the underlying drivers of poor outcomes in asthma. Many of the structural impediments to high quality asthma care at the society level (e.g. poverty, redlining, systemic racism) also are risk factors for worsened climate events and air pollution exposure. The individuals in these disproportionately affected groups are doubly affected by worsened exposure and worsened access to care for the resultant asthma exacerbations or incident asthma. More research is needed to understand the specific climate and air pollution mitigation efforts where disproportionately affected communities would derive the most benefit.

Effect of Community Water Service on Lead in Drinking Water in an Environmental Justice Community.

Multiple recent studies have found elevated lead (Pb) concentrations in tap water in U.S. homes relying on unregulated private wells. The main Pb source is dissolution from household plumbing, fixtures, and well components. Here, we leverage a natural experiment and citizen science approach to evaluate how extending community water service to an environmental justice community relying on private wells affects Pb in household water. We analyzed Pb in 260 first-draw kitchen tap water samples collected by individual homeowners over a 5-month period in residences that did and did not connect to the community system. Before the community water system was extended, 25% of homes had Pb > 15 µg/L (the U.S. regulatory action level for community water systems) in first-draw water samples. Pb was significantly correlated with nickel (ρ = 0.61), zinc (ρ = 0.50), and copper (ρ = 0.40), suggesting that corrosion of brass fittings and fixtures is the main Pb source. Among homes that connected to the community system, Pb decreased rapidly and was sustained at levels well below 15 µg/L over the study period. Overall, connecting to the municipal water supply was associated with a 92.5% decrease in first-draw tap water Pb.

Racism as a public health issue in environmental health disparities and environmental justice: working toward solutions.

BACKGROUND: Environmental health research in the US has shown that racial and ethnic minorities and members of low-socioeconomic groups, are disproportionately burdened by harmful environmental exposures, in their homes, workplace, and neighborhood environments that impact their overall health and well-being. Systemic racism is a fundamental cause of these disproportionate exposures and associated health effects. To invigorate and inform current efforts on environmental justice and to raise awareness of environmental racism, the National Institute of Environmental Health Sciences (NIEHS) hosted a workshop where community leaders, academic researchers, and NIEHS staff shared perspectives and discussed ways to inform future work to address health disparities. OBJECTIVES: To share best practices learned and experienced in partnerships between academic researchers and communities that are addressing environmental racism across the US; and to outline critical needs and future actions for NIEHS, other federal agencies, and anyone who is interested in conducting or funding research that addresses environmental racism and advances health equity for all communities. DISCUSSION: Through this workshop with community leaders and researchers funded by NIEHS, we learned that partnerships between academics and communities hold great promise for addressing environmental racism; however, there are still profound obstacles. To overcome these barriers, translation of research into plain language and health-protective interventions is needed. Structural changes are also needed in current funding mechanisms and training programs across federal agencies. We also learned the importance of leveraging advances in technology to develop creative solutions that can protect public health.
