Published: 2024-12-20
Subjects: Environmental Health and Protection, Environmental Monitoring, Environmental Public Health, Other Environmental Sciences, Sustainability
Satellite images of land surface temperatures (LST) are commonly used to identify areas within cities most prone to diurnal thermal discomfort, but they may not reflect the experiences of pedestrians. Here, we developed predictive statistical models for Physiological Equivalent Temperature (PET), an indicator of thermal discomfort, with easily accessible spatial predictors. For this, we measured [...]

Reducing pesticide use and restoring biodiversity are among the most pressing environmental challenges. Enhancing natural pest control ecosystem services through the integration of non-crop habitats (NCH) offers promising potential, creating a positive feedback loop by harnessing insect biodiversity to reduce pesticide reliance. Policy support is needed at the landscape level to encourage [...]
Potential effects of coagulation processes on phytoplankton mortality in the Elbe estuary from a Lagrangian point of view
Published: 2024-10-17
Subjects: Biogeochemistry, Environmental Health and Protection, Environmental Indicators and Impact Assessment, Environmental Monitoring, Oceanography, Water Resource Management
Within the Elbe estuary, a sudden change in depth occurs when the river enters the shipping channel in the Port of Hamburg. This change in depth correlates with a sharp decline in phytoplankton concentrations. This decline affects the estuarine food web and shifts the ecosystem from autotrophic to heterotrophic during the summer months. Previous studies have hypothesized that this collapse is [...]
Sensitivities of soil respiration and heterotrophic respiration to temperature in a cool-temperate forest with sika deer-induced understory vegetation alteration
Published: 2024-08-05
Subjects: Biogeochemistry, Environmental Health and Protection, Environmental Monitoring, Forest Biology, Forest Management, Soil Science, Terrestrial and Aquatic Ecology
Overpopulated ungulates reduce the biomass of understory vegetation and promote the expansion of unpalatable plants in world forests. These understory degradations possibly influence sensitivities of soil respiration (Rs) and heterotrophic respiration (Rh) to temperature and moisture. Here, we examined this possibility in a cool-temperate forest in southern Kyushu, Japan. At the study site, the [...]
Evaluating estimation methods for wildfire smoke and their implications for assessing health effects
Published: 2024-06-13
Subjects: Environmental Health and Protection, Environmental Public Health, Environmental Sciences, Public Health
Growing wildfire smoke represents a substantial threat to air quality and human health in the US and across much of the globe. However, the impact of wildfire smoke on human health remains imprecisely understood, due to uncertainties in both the measurement of population wildfire smoke exposure and dose-response functions linking exposure to health. Here, we compare daily wildfire smoke-related [...]
Wildfire smoke exposure and mortality burden in the US under future climate change

Subjects: Environmental Health and Protection, Environmental Indicators and Impact Assessment, Environmental Sciences, Public Health, Social and Behavioral Sciences
Wildfire activity has increased in the US and is projected to accelerate under future climate change. However, our understanding of the impacts of climate change on wildfire smoke and health remains highly uncertain. Here we quantify the mortality burden in the US due to wildfire smoke fine particulate matter (PM2.5) under future climate change. We construct an ensemble of statistical and machine [...]
Wildfires increasingly threaten oil and gas wells in the western United States with disproportionate impacts on marginalized populations
Published: 2023-11-15
Subjects: Environmental Health and Protection, Environmental Sciences, Environmental Studies, Oil, Gas, and Energy
The western United States is home to most of the nation’s oil and gas production and, increasingly, wildfires. We examined historical threats of wildfires for oil and gas wells, the extent to which wildfires are projected to threaten wells as climate change progresses, and exposure of human populations to these wells. From 1984–2019, we found that cumulatively 102,882 wells were [...]

Rapid urbanization has dramatically increased the demand for river sand, leading to soaring sand extraction rates that often exceed natural replenishment in many rivers globally. However, our understanding of the geomorphic and social-ecological impacts arising from Sand Mining (SM) remains limited, primarily due to insufficient data on sand extraction rates. Conventionally, bathymetry surveys [...]
Evaluating the spatial patterns of NOx emissions in polluted areas with TROPOMI NO2
Published: 2023-05-18
Subjects: Atmospheric Sciences, Environmental Health and Protection, Environmental Monitoring
Satellite datasets are increasingly used to evaluate NOx emissions inventories. Such studies often require the use of a chemical transport model or a complex statistical framework to account for meteorological factors that can complicate the comparison. Here, we apply a novel method to compare inventory-based emissions directly to Tropospheric Monitoring Instrument (TROPOMI) NO2 data without a [...]
Quantifying fire-specific smoke severity
Published: 2023-02-17
Subjects: Earth Sciences, Environmental Health and Protection, Environmental Monitoring, Environmental Sciences, Physical Sciences and Mathematics
Rapidly changing wildfire regimes across the Western US has driven more frequent and severe wildfires, resulting in wide-ranging societal threats from the wildfires themselves and the smoke that they generate. However, common measures of fire severity focus on what is burned and do not account for the societal impacts of the smoke generated from each fire. We combine satellite-derived fire scars, [...]
Wildfire influence on recent US pollution trends
Published: 2022-12-16
Subjects: Environmental Health and Protection, Environmental Monitoring, Environmental Public Health, Environmental Studies
Steady improvements in ambient air quality in the US over the past several decades have led to large public health benefits. However, recent trends in PM2.5 concentrations, a key pollutant, have stagnated or begun to reverse throughout much of the US. We quantify the contribution of wildfire smoke to these trends and find that since 2016, wildfire smoke has significantly slowed or reversed [...]
