Controlled human exposures to ambient pollutant particles in susceptible populations.
(Environmental health : a global access science source, 2009-01)Epidemiologic studies have established an association between exposures to air pollution particles and human mortality and morbidity at concentrations of particles currently found in major metropolitan areas. The adverse ... -
Estimation of in-canopy ammonia sources and sinks in a fertilized Zea mays field.
(Environ Sci Technol, 2010-03-01)An analytical model was developed to describe in-canopy vertical distribution of ammonia (NH(3)) sources and sinks and vertical fluxes in a fertilized agricultural setting using measured in-canopy mean NH(3) concentration ... -
Fate of products of degradation processes: consequences for climatic change.
(Chemosphere, 1999-03)The end products of atmospheric degradation are not only CO2 and H2O but also sulfate and nitrate depending on the chemical composition of the substances which are subject to degradation processes. Atmospheric degradation ... -
Implications of shale gas development for climate change.
(Environ Sci Technol, 2014)Advances in technologies for extracting oil and gas from shale formations have dramatically increased U.S. production of natural gas. As production expands domestically and abroad, natural gas prices will be lower than without ... -
Inflammatory Cytokines and White Blood Cell Counts Response to Environmental Levels of Diesel Exhaust and Ozone Inhalation Exposures.
(PloS one, 2016-01)Epidemiological observations of urban inhalation exposures to diesel exhaust (DE) and ozone (O3) have shown pre-clinical cardiopulmonary responses in humans. Identifying the key biological mechanisms that initiate these ... -
Long-term dynamics of death rates of emphysema, asthma, and pneumonia and improving air quality.
(Int J Chron Obstruct Pulmon Dis, 2014)BACKGROUND: The respiratory tract is a major target of exposure to air pollutants, and respiratory diseases are associated with both short- and long-term exposures. We hypothesized that improved air quality in North Carolina ... -
Particulate allergens potentiate allergic asthma in mice through sustained IgE-mediated mast cell activation.
(2010)In recent years, the incidence of allergic asthma as well as the severity of disease has rapidly increased worldwide. Numerous epidemiological studies have related the exacerbation of allergic asthma with exposure to increased ... -
Pollutant particles produce vasoconstriction and enhance MAPK signaling via angiotensin type I receptor.
(Environmental health perspectives, 2005-08)Exposure to particulate matter (PM) is associated with acute cardiovascular mortality and morbidity, but the mechanisms are not entirely clear. In this study, we hypothesized that PM may activate the angiotensin type 1 receptor ... -
Seasonal variations in air pollution particle-induced inflammatory mediator release and oxidative stress.
(Environmental health perspectives, 2005-08)Health effects associated with particulate matter (PM) show seasonal variations. We hypothesized that these heterogeneous effects may be attributed partly to the differences in the elemental composition of PM. Normal human ... -
Social and physical environments and disparities in risk for cardiovascular disease: the healthy environments partnership conceptual model.
(Environ Health Perspect, 2005-12)The Healthy Environments Partnership (HEP) is a community-based participatory research effort investigating variations in cardiovascular disease risk, and the contributions of social and physical environments to those variations, ... -
Temporal and spatial distribution of health, labor, and crop benefits of climate change mitigation in the United States.
(Proceedings of the National Academy of Sciences of the United States of America, 2021-11)Societal benefits from climate change mitigation accrue via multiple pathways. We examine the US impacts of emission changes on several factors that are affected by both climate and air quality responses. Nationwide benefits ... -
The role of reactive oxygen and nitrogen species in the response of airway epithelium to particulates.
(Environ Health Perspect, 1997-09)Epidemiologic and occupational studies indicate adverse health effects due to inhalation of particulate air pollutants, but precise biologic mechanisms responsible have yet to be fully established. The tracheobronchial epithelium ... -
The toxicology of climate change: environmental contaminants in a warming world.
(Environ Int, 2009-08)Climate change induced by anthropogenic warming of the earth's atmosphere is a daunting problem. This review examines one of the consequences of climate change that has only recently attracted attention: namely, the effects ... -
Up-regulation of tissue factor in human pulmonary artery endothelial cells after ultrafine particle exposure.
(Environmental health perspectives, 2007-04)BACKGROUND: Epidemiology studies have linked exposure to pollutant particles to increased cardiovascular mortality and morbidity, but the mechanisms remain unknown. OBJECTIVES: We tested the hypothesis that the ultrafine ...
