Acrolein is an irritating aldehyde generated during combustion of organic compounds. Altered autonomic activity has been documented following acrolein inhalation, possibly impacting myocardial synchrony and function. Given the ubiquitous nature of acrolein in the environment, we ...

This is publication for a peer review journal.

Ozone-induced systemic effects are modulated through activation of the neuro-hormonal stress response pathway. Adrenal demedullation (DEMED)or bilateral total adrenalectomy (ADREX) inhibits systemic and pulmonary effect of acute ozone exposure. To understand the influence of adre...

Rationale: We have shown that acute ozone inhalation promotes activation of the sympathetic and hypothalamic-pituitary-adrenal (HPA) axis leading to release of cortisol and epinephrine from the adrenals. Adrenalectomy (ADREX) inhibits ozone-induced pulmonary vascular leakage and ...

The work here complements the overview analysis of the modelling systems participating in the third phase of the Air Quality Model Evaluation International Initiative (AQMEII3) by focusing on the performance for hourly surface ozone by two modelling systems, Chimere for Europe an...

This presentation describes an EPA effort to improve the understanding of well pad emissions and remote measurement methods, and identify areas where future work is needed. Funded through an R8 RARE, R8, ORD, and OAQPS conducted a two-phase project to explore a novel measuremen...

Children are more vulnerable to exposures from their everyday environments compared to adults. Children from Tribal communities have a greater burden of adverse health and well-being outcomes versus children from other communities in the U.S. (US DHHS 2016). Stressors from chi...

Dr. Michael Breen is leading the development of air pollution exposure models, integrated with novel personal sensor technologies, to improve exposure and risk assessments for individuals in health studies. He is co-investigator for multiple health studies assessing the exposure ...

Air Quality and Heart Health: An Emerging Topic for Heart Month: Ambient air particle pollution increases short- and long-term cardiovascular morbidity and mortality. Older-people, those with pre-existing heart disease and lung disease and diabetes are at higher risk. Mechanism...

Dr. Cascio will share with a broad range of federal agencies current understanding of the links between air quality and cardiovascular health. The key facts include that air pollution contributes a high attributable health burden. That certain well-defined vulnerable subpopulat...

Review of the use of green infrastructure for local air quality mitigation

BACKGROUND: Injury to the airways after smoke inhalation is a major mortality risk factor in victims of burn injuries, resulting in a 15-45% increase in patient deaths. Damage to the airways by smoke may induce acute respiratory distress syndrome (ARDS), which is partly character...

Nitrogen (N) export from the Mississippi River Basin contributes to seasonal hypoxia in the Gulf of Mexico (GOM). We explored monthly dissolved inorganic N (DIN) export to the GOM for a historical year (2002) and two future scenarios (year 2022) by linking macroeonomic energy, ag...

This paper describes the development of a new artificial turf surrogate surface (ATSS) sampler for use in the measurement of mercury (Hg) dry deposition. In contrast to many existing surrogate surface designs, the ATSS utilizes a three-dimensional deposition surface that may more...

The overall objective of this program is to characterize fungal and bacterial populations in the MPC residences in San Juan, Puerto Rico, following flooding events. These profiles will be generated by comparing the fungal and bacterial populations in two groups of residences: hom...

Empowering Sustainability is an initiative at the University of California, Irvine, dedicated to connecting sustainability leaders (fellows) across generations, countries, and disciplines through the exchange of ideas and experiences related to all aspects of sustainability, and ...

Hydrologic responses vary spatially and temporally according to watershed characteristics. In this study, the hydrologic models that we developed earlier for the Little Miami River (LMR) and Las Vegas Wash (LVW) watersheds were used for detail sensitivity analyses. To compare the...

The U.S. pulp and paper industry utilizes a variety of fuels to provide energy for process needs. Energy production results in air emissions of sulfur dioxide (SO2), nitrogen oxides (NOX), particulate matter (PM), and greenhouse gases such as carbon dioxide (CO2). Air emissions f...

The current study presents evidence on metallic and metal oxide engineered nanomaterial (ENM) emissions into the environment and an analytic perspective of the outcomes of evaluated studies with respect to different individual end points along the lifecycle trajectory. The key fi...

The Tropospheric Ozone (O3) Lidar Network (TOLNet) provides time/height O3 measurements from near the surface to the top of the troposphere to describe in high-fidelity spatial-temporal distributions, which is uniquely useful to evaluate the temporal evolution of O3 profiles in a...

Hazard assessment for nanomaterials often involves applying in vitro dose-response data to estimate potential health risks that arise from exposure to products that contain nanomaterials. However, much uncertainty is inherent in relating bioactivities observed in an in vitro syst...

ACKGROUND: Household air pollution from solid fuel burning is a leading contributor to disease burden globally. Fine particulate matter (PM2.5) is thought to be responsible for many of these health impacts. A co-pollutant, carbon monoxide (CO) has been widely used as a surrogate...

Aircraft measurements made downwind from specific coal fired power plants during the 2013 Southeast Nexus field campaign provide a unique opportunity to evaluate single source photochemical model predictions of both O3 and secondary PM2.5 species. The model did well at predicting...

We estimate the damage costs associated with the institutional nitrogen (N) footprint and explore how this information could be used to create more sustainable institutions. Potential damages associated with the release of NOx and N2O to air and release of N to water were estima...

Background/Question/Methods: Release of N to air, land and water has a host of effects on human health, ecosystems and the economy, many of which scientists and economists are just beginning to develop methods to quantify. In order to understand the broader connections to sustai...
