Assessing PM 2.5 pollution in the Northeastern United States from the 2023 Canadian wildfire smoke
Between June 6 and 8, 2023, wildfires in Quebec, Canada generated massive smoke plumes that traveled long distances and deteriorated air quality across the Northeastern United States (US). Surface daily PM 2.5 observations exceeded 100 μ g m -3 , affecting major cities such as New York City and Philadelphia, while many areas lacked PM 2.5 monitors, making it difficult to assess local air quality conditions. To address this gap, we developed a WRF…
A prototype early warning system for diarrhoeal disease to combat health threats of climate change in the asia-pacific region
Ongoing climate variability and change are increasing the burden of diarrhoeal disease worldwide. Meaningful early warning systems with adequate lead times (weeks to months) are needed to guide public health decision–making and enhance community resilience against health threats posed by climate change. Toward this goal, we trained various machine-learning models to predict diarrhoeal disease rates in Nepal (2002–2014), Taiwan (2008–2019), and Vi…
Effects of Ambient Temperature, Relative Humidity, and Precipitation on Diarrhea Incidence in Surabaya
This study identified a high incidence of diarrhea in the rainy season and in the deficient developed regions of Surabaya, providing evidence that weather magnifies the adverse effects of inadequate environmental sanitation. This study suggests the local environmental and health sectors codevelop a weather-based early warning system and improve local sanitation practices as prevention measures in response to increasing risks of infectious disease…
Effects of Climatic Factors on Diarrheal Diseases among Children below 5 Years of Age at National and Subnational Levels in Nepal
Introduction: The incidence of diarrhea, a leading cause of morbidity and mortality in low-income countries such as Nepal, is temperature-sensitive, suggesting it could be associated with climate change. With climate change fueled increases in the mean and variability of temperature and precipitation, the incidence of water and food-borne diseases are increasing, particularly in sub-Saharan Africa and South Asia. This national-level ecological st…
Global Population Exposed to Extreme Events in the 150 Most Populated Cities of the World
Climate change driven increases in the frequency of extreme heat events (EHE) and extreme precipitation events (EPE) are contributing to both infectious and non-infectious disease burden, particularly in urban city centers. While the share of urban populations continues to grow, a comprehensive assessment of populations impacted by these threats is lacking. Using data from weather stations, climate models, and urban population growth during 1980-…
Food insecurity and compound environmental shocks in Nepal
Detecting the net effect of flooding on infectious diarrheal disease in Anhui Province, China
Though a number of studies have shown positive relationships between flooding events and infectious diarrhea, there is a paucity of rigorous evidence regarding the net effect of flooding on diarrhea incidence, controlling for existing pre-trends and meteorological confounders. The study treats the 2016 catastrophic flood event in Anhui Province, China as a natural experiment using a difference-in-differences design with propensity score matching …
Development of a Cumulative Stressors and Resiliency Index to Examine Environmental Health Risk
Several South Carolina (SC) communities are overburdened by pollution and may suffer from environmental health disparities. To address these disparities, improvements in screening approaches are needed to understand and mitigate risk. The purpose of this study was to develop a cumulative stressors and resiliency index (CSRI) that includes environmental stressors and resiliency buffers to rank human health and environmental risks at the census tra…
Antibiotic Concentrations Decrease during Wastewater Treatment but Persist at Low Levels in Reclaimed Water
Reclaimed water has emerged as a potential irrigation solution to freshwater shortages. However, limited data exist on the persistence of antibiotics in reclaimed water used for irrigation. Therefore, we examined the fate of nine commonly-used antibiotics (ampicillin, azithromycin, ciprofloxacin, linezolid, oxacillin, oxolinic acid, penicillin G, pipemidic acid, and tetracycline) in differentially treated wastewater and reclaimed water from two U…
Place-based perceptions of the impacts of fracking along the Marcellus Shale
We examined community perspectives and experiences with fracking in Doddridge County, West Virginia, USA as part of a larger assessment to investigate the potential health impacts associated with fracking in neighboring Maryland, USA. In November 2013, we held two focus groups with community residents who had been impacted by fracking operations and conducted field observations in the impacted areas. Employing grounded theory, we conducted qualit…
Global, regional, and national comparative risk assessment of 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks in 188 countries, 1990–2013
A comparative risk assessment of burden of disease and injury attributable to 67 risk factors and risk factor clusters in 21 regions, 1990–2010
Terrorism, civil war, one-sided violence and global burden of disease
Armed conflict and related violence, including terrorism and one-sided violence, has profound effects on people's health and lives. The purpose of this study was to determine the relationship between deaths due to terrorism, civil war and one-sided violence from 1994-2000 and disability-adjusted life years (DALYs) occurring in 2002 attributable to all causes and specific communicable and noncommunicable diseases. Deaths resulting from terrorism, …
