A Broad Overview of EPA Protocol Gases (PRESENTATION)
A high level presentation for their senior people, lasting perhaps 45 minutes, covering a history of the protocol program, outcome focused… the why’s and how’s, and how you measure success.
A Chemical Activity Approach to Exposure and Risk Assessment of Chemicals (JOURNAL)
To support the goals articulated in the vision for exposure and risk assessment in the twenty-first century, we highlight the application of a thermodynamic chemical activity approach for the exposure and risk assessment of chemicals in the environment. The present article descri...
A Comparison of Simulated and Field-Derived Leaf Area Index (LAI) and Canopy Height Values from Four Forest Complexes in the Southeastern USA (JOURNAL)
Vegetative leaf area is a critical input to models that simulate human and ecosystem exposure to atmospheric pollutants. Leaf area index (LAI) can be measured in the field or numerically simulated, but all contain some inherent uncertainty that is passed to the exposure assessmen...
A Maieutic Exploration of Nudging Strategies for Regional Climate Applications Using the WRF Model (JOURNAL)
The use of nudging in the Weather Research and Forecasting (WRF) Model to constrain regional climate downscaling simulations is gaining in popularity because it can reduce error and improve consistency with the driving data. While some attention has been paid to whether nudging i...
A Proof-of-Concept Approach for Quantifying Multi-Pollutant Health Impacts Using the Open-Source BenMAP-CE Software Program (PRESENTATION)
Background Air pollution risk assessments often employ effect coefficients from epidemiologic studies to quantify the public health impact of changes in air quality. Partly due to data and methodological limitations, epidemiologic studies have traditionally characterized the heal...
A Sensitivity Study of Convection Parameterizations in MPAS-A Utilized in Conjunction with USEPA Physics Options (PRESENTATION)
The Model for Prediction Across Scales – Atmosphere (MPAS-A) is the meteorological foundation for a next generation global air quality modeling system currently being developed at the U.S. Environmental Protection Agency (USEPA). In recent years, meteorological fields for r...
A case study evaluation of fog simulation using two land-surface (PRESENTATION)
Despite its importance to transportation safety and ecosystem health related to pollutant and nutrient deposition, the simulation of fog lags the simulation of other meteorological phenomena due in large part to its complexity and limitations of model resolution. Accordingly, th...
A glucocorticoid signaling-related adverse outcome pathway network links inhaled pollutants with multiple adverse outcomes (PRESENTATION)
The Adverse Outcome Pathway (AOP) framework represents an ideal tool for integrating diverse data relating chemical exposures to adverse outcomes. Glucocorticoid signaling is tightly controlled and numerous adverse health outcomes have been associated with either elevation or sup...
A primer on environmental life-cycle based decision support tools for sustainable materials management (PRESENTATION)
This is the presentation for the invited lecture at Rutgers University. The lecture will be part of online course titled "Sustainability Decision Tools" in Spring 2018.
A proof-of-concept for linking the global meteorological model, MPAS-A with the air quality model, CMAQ (PRESENTATION)
Researchers who perform air quality modeling studies usually do so on a regional scale. Typically, the boundary conditions are generated by another model which might have a different chemical mechanism, spatial resolution, and/or map projection. Hence, a necessary conversion/inte...
Accountability: Evaluating the Impact of Regulatory Policies on Air Quality, Human Health, and the Environment (PRESENTATION)
This presentation discusses "accountability"; e.g., do emission-control regulations really reduce exposure to pollutants and improve human health? In this presentation, we provide examples of how to examine this and related questions.
Acrolein-induced arrhythmias and autonomic imbalance due to early life persistent vitamin D deficiency in mice is mediated by the putative anti-aging factor klotho. (PRESENTATION)
Although epidemiological, human and animal data have conclusively linked air pollution exposure to adverse cardiovascular outcomes, the severity of responses depends on a number of intrinsic (diet, underlying disease, etc) and extrinsic (e.g. co-stressors) factors. As such, cardi...
Acute Peat Smoke Inhalation Increases Blood Pressure and Cardiac Arrhythmia Risk in Rats (PRESENTATION)
Wildland fires are increasingly linked to adverse health impacts related to poor air quality. For instance, short-term exposure to smoldering peat (SP) air pollution in eastern North Carolina during separate burns in 2008 and 2011 led to increased cardiopulmonary emergency room v...
Adding four-dimensional data assimilation by analysis nudging to the Model for Prediction Across Scales – Atmosphere (version 4.0) (JOURNAL)
The Model for Prediction Across Scales – Atmosphere (MPAS-A) has been modified to allow four-dimensional data assimilation (FDDA) by the nudging of temperature, humidity, and wind toward target values predefined on the MPAS-A computational mesh. The addition of nudging allo...
Additional Benefits of Federal Air-Quality Rules: Model Estimates of Controllable Biogenic Secondary Organic Aerosol (JOURNAL)
Atmospheric models that accurately describe the fate and transport of trace species for the right reasons aid in the development of effective air-quality management strategies that safeguard human health. Controllable emissions facilitate the formation of biogenic secondary organ...
Adrenergic and glucocorticoid receptor antagonists reduce ozone-induced lung injury and inflammation (JOURNAL)
Recent studies showed that the circulating stress hormones, epinephrine and corticosterone/cortisol, are involved in mediating ozone-induced pulmonary effects through the activation of the sympathetic-adrenal-medullary (SAM) and hypothalamus-pituitary-adrenal (HPA) axes. Hence, w...
Advancing Next Generation Emission Measurements, Novel Volatile Organic Compounds Methods, and Citizen Science (PRESENTATION)
Energy production operations, refineries, chemical plants, and other industrial and waste facilities can emit volatile organic compounds, hazardous air pollutants and odorous species from fugitive leaks, process malfunctions, and area sources that are difficult to detect and char...
Advancing public participation in scientific research: A framework for leveraging public participation in environmental health and emergency response research (PRESENTATION)
This research paper uses case analysis methods to understand why participants engage in this innovative approach public participation in scientific research, and what they hope that will mean for their community. The research questions that guide this analysis are: 1) what factor...
Air Pollution Exposure Modeling for Epidemiology Studies and Public Health (PRESENTATION)
Air pollution epidemiology studies of ambient fine particulate matter (PM2.5) often use outdoor concentrations as exposure surrogates. These surrogates can induce exposure error since they do not account for (1) time spent indoors with ambient PM2.5 levels attenuated from outdoor...
