Critical loads (CLs) and target loads (TLs) of atmospheric deposition of sulfur (S) and nitrogen (N) specify the thresholds of air pollution above which damage to ecosystems is expected to occur and are used to inform environmental regulation and natural resource management. Mode...

Forest biological disturbance agents (BDAs) are insects, pathogens, and parasitic plants that cause tree decline and mortality. Traditionally, BDAs were thought to increase the likelihood and severity of fire by adversely affecting forest health. However, there are a wide range o...

Projected effects of climate change on growth and productivity of U.S. forest species, which are then modeled in a forestry market model to investigate broader economic effects.

In April of 2018, an optical gas imaging (OGI) and full flow sampler (FFS) emissions measurement study of pneumatic controllers (PCs) at 15 oil and natural gas production sites in West Virginia was conducted. A total of 391 PC systems supporting 66 working wells were found. All w...

Wildland fires are diminishing air quality on a seasonal and regional basis, raising concerns about respiratory health risks to the public and occupational groups. This American Thoracic Society (ATS) workshop was convened to meet the growing health threat of wildland fire smoke....

Simulation models such as the Hydrologic Simulation Program &ndash; FORTRAN (HSPF) and Soil&ndash;Water Assessment Tool (SWAT) are frequently used to project the responses of watershed processes to climate change, but do not always represent the effects of changes in atmospheric ...

Abstract: As the climate warms, wildfires are increasing in size and intensity, posing a risk to human health and sensitive ecosystems. Studies have reported on particulate matter (PM) in wildfire smoke; however, the chemicals associated with PM, including toxic metals, have rece...

Objective(s) This study explored the feasibility, acceptability, preliminary impact, and functionality of two risk reduction mobile application (app) interventions on asthma outcomes as compared to a control arm during wildfire season. Design Three-arm, 8-week randomized clinic...

We used a dynamic soil-vegetation model (ForSAFE-Veg) to simulate responses to future scenarios of atmospheric deposition and climate change across 23 Northeastern hardwood stands. Specifically, we simulated soil percent base saturation, acid neutralizing capacity (ANC), nitrate ...

Coastal infrastructure has increasingly become more vulnerable to flooding. While many studies have shown that extreme events such as storm surge threaten to be ever more costly, less damaging but more frequent flood events remain understudied but potentially carry a comparable l...

This study estimates an ensemble of future changes in coastal wetland areas considering both sea level rise, future greenhouse gas emissions, and accretion rate uncertainty, using outputs from the National Ocean and Atmospheric (NOAA) marsh migration model.

Forest understory plant communities in the United States are diverse and often sensitive to changes in climate and atmospheric inputs of nitrogen (N) caused by air pollution. Recently, understory vegetation response functions (expressed as Probability of Occurrence of Plant Speci...

Abstract: It is proposed that the mechanistic basis for non-neoplastic lung injury with cigarette smoking is a disruption of iron homeostasis in cells after exposure to cigarette smoke particle (CSP). Following the complexation and sequestration of intracellular iron by CSP, the ...

Watershed modeling in 20 large, United States (U.S.) watersheds addresses gaps in our knowledge of streamflow, nutrient (nitrogen and phosphorus), and sediment loading sensitivity to mid-21st Century climate change and urban/residential development scenarios. Use of a consistent ...

Startling images of smoke-filled skies have filled the news and social media in recent years during major wildfires in the U.S. (Figure 1). In 2020, over 10 million acres burned from nearly 59,000 wildland fires, including wildfires and prescribed fires (National Interagency Coor...

Air pollution risk assessments typically estimate ozone-attributable mortality counts using concentration&ndash;response (C-R) parameters from epidemiologic studies that treat temperature as a potential confounder. However, some recent epidemiologic studies have indicated that te...

&nbsp; Air pollution has been associated with metabolic diseases and hepatic steatosis-like changes. We have shown that ozone alters liver gene expression for metabolic processes through neuroendocrine activation. This study aimed to further characterize ozone-induced changes and...

To model international trade of forest products we use a gravity model of trade. In modeling trade, we estimate the impact of importer gross domestic product (GDP), exporter GDP, and distance between trading partners using Poisson pseudomaximum likelihood (PPML). When estimating...

In this paper, we examine how climate change will impact outdoor recreation in the continental United States using data on time allocation from the American Time Use Survey (ATUS). We apply a partially non-parametric regression approach to document how weather historically affect...

Climate change has the potential to affect agricultural productivity and food supply through a wide array of mechanisms, as described in a large body of literature. Both physical and economic models have been used to examine potential future agricultural implications of climate c...

We build on climate change and suicide-focused mental health research to quantify and monetize changes in suicide incidence across the U.S. in response to increasing levels of warming based on six climate projections.

Nitrophenols (NPs) are&nbsp;hazardous pollutants&nbsp;found in various environmental matrices, including ambient fine&nbsp;particulate matter&nbsp;(PM2.5), agricultural residues, rainwater, wildfires, and&nbsp;industrial wastes. This study showed for the first time the effect of ...

Best Management Practices (BMPs) are used to mitigate the impacts of human activities on land and water resources. Most BMPs function via physical, chemical, and biological processes that are strongly dependent on weather and climate. Changing climatic conditions can lead to incr...

The Environmental Effects Assessment Panel of the Montreal Protocol under the United Nations Environment Programme evaluates effects on the environment and human health that arise from changes in the stratospheric ozone layer and concomitant variations in ultraviolet (UV) radiati...

Airborne particulate matter (PM) is a pollutant of concern not only because of its adverse effects on human health but also on visibility and the radiative budget of the atmosphere. PM can be considered as a sum of solid/liquid species covering a wide range of particle sizes with...
