A Climate Central analysis of 239 U.S. cities reveals that 83% have seen an increase in annual average days with a heat index of 90°F or higher since 1979. The report highlights the danger of exertional heat illness (EHI), noting that heat-related illnesses are a leading cause of death or disability among high school athletes. It details regional trends, such as substantial increases in the Pacific Northwest and extended heat seasons in the South, while noting that climate change is intensifying these trends. The document provides safety recommendations for coaches and athletes, including the use of wet bulb globe temperature (WBGT) monitoring and gradual heat acclimatization.

The report finds that 14 industrial facilities in South Africa's Mpumalanga Highveld Priority Area (HPA) caused between 305 and 650 early deaths in 2016 due to PM2.5 pollution. The most significant contributors were the Lethabo, Kendal, and Kriel power stations. Modeling indicates that compliance with the 2020 Minimum Emission Standards (MES) would reduce these annual early deaths by 60%, preventing between 182 and 388 deaths. The report also highlights severe exceedances of World Health Organization (WHO) guidelines for SO2 and NO2, particularly at sensitive sites like schools and hospitals. In 2016, these 14 facilities accounted for up to 92% of the daily ambient SO2 limit, suggesting that national air quality standards cannot be met without reducing emissions from these specific sources.

The report identifies a 'double jeopardy' for residents of east Houston's Harrisburg/Manchester and Galena Park communities, who face both daily chronic exposure to toxic air pollutants and a high risk of acute catastrophic chemical accidents. Using EPA data, the study finds that these marginalized communities have significantly higher toxic concentrations, cancer risks, and respiratory hazards than the more affluent West Oaks/Eldridge and Bellaire neighborhoods. The authors attribute these disparities to a lack of citywide zoning in Houston and the concentration of high-risk industrial facilities in low-income areas, recommending stricter regulations on safer chemicals, improved fenceline monitoring, and the implementation of formal health-impact assessments.

The report identifies a 'double jeopardy' for residents of Harrisburg/Manchester and Galena Park in east Houston, who face both higher daily exposure to toxic air pollutants and greater proximity to high-risk chemical facilities than residents of West Oaks/Eldridge and Bellaire in west Houston. This disparity results in significantly higher cancer and respiratory illness risks for east Houston residents, exacerbated by a lack of comprehensive zoning laws and socioeconomic determinants.

The report identifies a 'double jeopardy' for residents of Harrisburg/Manchester and Galena Park in east Houston, who face both significantly higher daily exposure to toxic air pollutants and a greater risk of catastrophic chemical accidents due to their proximity to high-risk industrial facilities. In contrast, wealthier communities in west Houston, such as Bellaire and West Oaks/Eldridge, have far lower exposure levels and fewer nearby hazardous facilities. The document advocates for systemic regulatory changes, including the adoption of safer technologies, improved emergency communication, and the implementation of health impact assessments to address these environmental justice disparities.

The document details the exposure of the Manchester community in Houston to hazardous air pollutants emitted by nearby industrial facilities, including oil refineries and chemical plants. It identifies six specific toxic substances—1,3-Butadiene, Benzene, Ethylbenzene, Styrene, Toluene, and Xylene—and describes their potential short- and long-term health effects, such as cancer and respiratory issues. The report emphasizes that this 'front-line' community, characterized by high minority and low-income populations, faces disproportionate environmental burdens and lacks the resources to hold polluters accountable.

The community of Manchester in Houston, Texas, faces significant public health threats due to a dense concentration of industrial facilities, including oil refineries and chemical plants. Residents, who are 98 percent minority and 65 percent low-income, are exposed to hazardous air pollutants such as benzene and 1,3-butadiene. The document highlights the disproportionate burden of pollution on low-income communities of color and calls for local officials to prioritize public health and safety in fence-line communities.

The report argues that the proposed Oakland Bulk and Oversized Terminal (OBOT) poses significant risks to public health, water security, and local ecosystems, particularly if used to export coal. The author highlights that current design plans are conceptual and lack enforceable controls for dust and emissions. Key concerns include the consumption of 79.2 million gallons of water annually for dust control during a record drought, the release of up to 18,300 tons of coal dust per year within California from uncovered rail cars, and increased cancer risks from diesel particulate matter in West Oakland. Additionally, the report notes that the project's scale would cause significant traffic congestion at 55 at-grade rail crossings and create substantial noise pollution. The author concludes that these impacts were not addressed in the project's CEQA review.

The Centre for Environmental Rights (CER) submitted a statement to the Department of Environmental Affairs (DEA) opposing Eskom's applications to postpone compliance with Minimum Emission Standards (MES). The CER argues that Eskom failed to provide required health impact assessments and future compliance plans, while monitoring data indicates that Eskom's emissions cause frequent, year-round exceedances of air quality guidelines, contributing to significant regional health risks.

Earthjustice and a coalition of nonprofit organizations petition the EPA to regulate oil and gas wells as area sources, arguing that the rapid expansion of drilling—particularly via hydraulic fracturing—in metropolitan areas poses a non-negligible risk to public health. The document details the emission of toxic air pollutants such as benzene and formaldehyde, highlights the vulnerability of children and overburdened communities, and identifies significant regulatory gaps in existing EPA rules. It concludes that available technologies, such as green completions and vapor recovery units, can substantially reduce these emissions.

The report provides a comprehensive health risk assessment of sanitation technologies, categorizing them into functional groups: user interface, collection and storage/treatment, conveyance, semi-centralized treatment, and reuse/disposal. It identifies critical exposure points for users, workers, farmers, and the community, emphasizing that technical barriers (like storage time and pH elevation) must be combined with socio-cultural behavioral changes (such as hand-washing) to effectively break the cycle of disease transmission. The document analyzes specific technologies—ranging from open defecation and pit latrines to advanced wastewater treatment plants—and provides epidemiological evidence on their impact on diarrhoeal diseases and helminth infections.

The report details the environmental and health risks associated with the disposal of over 100 million tons of annual coal and oil combustion waste in the United States. It highlights that 76 million tons are typically disposed of in unlined, unmonitored onsite lagoons and landfills, leading to groundwater contamination and ecological damage. The authors argue that current state-level regulations are inconsistent and insufficient, and that the EPA's preliminary determination to maintain a regulatory exemption for these wastes ignores significant risks to low-income communities and people of color. The document calls for federal oversight under RCRA to mandate modern environmental controls like liners and groundwater monitoring.

This document consists of a final project report (2006) and a related academic paper (2013) regarding the South Durban Health Study. The research, funded by the eThekwini Municipality as part of the Multipoint Plan, assessed the impact of industrial pollution on the respiratory health of schoolchildren and adults in south Durban compared to a non-industrial northern control area. The study found that children in the industrial south had a significantly higher risk of persistent asthma and marked airway hyperreactivity, with evidence that ambient pollutants like SO2, NO2, and particulate matter contributed to decrements in lung function, particularly in sensitive subpopulations.

This November 2006 report by Airshed Planning Professionals (Pty) Ltd, commissioned by Eskom Holdings Limited, assesses the inhalation-related health risks associated with the existing Matimba Power Station and the proposed Project Alpha power station in the Lephalale area of Limpopo Province. The study focuses on particulate matter (PM10), sulphur dioxide (SO2), and nitrogen dioxide (NO2), utilizing CALPUFF dispersion modelling and 2001 census population data to estimate premature mortalities and respiratory hospital admissions.

This report section details a health risk assessment for the area surrounding the Matimba Power Station in Limpopo Province, South Africa. It evaluates the impact of air pollutants—specifically sulphur dioxide (SO2), nitrogen dioxide (NO2), and particulate matter (PM10)—from power station emissions, household fuel burning, and brickmaking on non-accidental mortality and respiratory hospital admissions.

This report reviews risk factors to quantify the potential health impacts of particulate matter (PM10, PM2.5), sulphur dioxide (SO2), and nitrogen dioxide (NO2) emissions from various Eskom operations. It synthesizes global epidemiological data from organizations like the WHO and USEPA to establish risk estimates for mortality and morbidity, while incorporating South African provincial population and health data to support a health risk assessment.

The document highlights the risk of hexavalent chromium, a carcinogen, leaching from unlined coal ash disposal sites into groundwater. It criticizes the EPA for treating the chemical as a non-carcinogen when ingested in its coal ash rule-making and calls for the regulation of coal ash as a hazardous waste.
