• Acute and Chronic Effects of Particles on Hospital Admissions in New England ﻿

(Public Library of Science, 2012)
Background: Many studies have reported significant associations between exposure to $PM_{2.5}$ and hospital admissions, but all have focused on the effects of short-term exposure. In addition all these studies have relied ...
• Air Pollution Exposure and Abnormal Glucose Tolerance during Pregnancy: The Project Viva Cohort ﻿

(National Institute of Environmental Health Sciences, 2014)
Background: Exposure to fine particulate matter (PM with diameter ≤ 2.5 μm; PM2.5) has been linked to type 2 diabetes mellitus, but associations with hyperglycemia in pregnancy have not been well studied. Methods: We studied ...
• Air pollution exposure and lung function in highly exposed subjects in Beijing, China: a repeated-measure study ﻿

(BioMed Central, 2014)
Background: Exposure to ambient particulate matter (PM) has been associated with reduced lung function. Elemental components of PM have been suggested to have critical roles in PM toxicity, but their contribution to ...
• Ambient air pollution, lung function, and airway responsiveness in asthmatic children ﻿

(Elsevier BV, 2016)
Background: Although ambient air pollution has been linked to reduced lung function in healthy children, longitudinal analyses of pollution effects in asthma are lacking. Objective: To investigate pollution effects in ...
• Associations between air pollution and perceived stress: the Veterans Administration Normative Aging Study ﻿

(BioMed Central, 2015)
Background: There is mixed evidence suggesting that air pollution may be associated with increased risk of developing psychiatric disorders. We aimed to investigate the association between air pollution and non-specific ...
• Associations of Fine Particulate Matter Species with Mortality in the United States: A Multicity Time-Series Analysis ﻿

(NLM-Export, 2014)
Background: Epidemiological studies have examined the association between PM2.5 and mortality, but uncertainty remains about the seasonal variations in PM2.5-related effects and the relative importance of species. Objectives: ...
• Brachial Artery Responses to Ambient Pollution, Temperature, and Humidity in People with Type 2 Diabetes: A Repeated-Measures Study ﻿

(National Institute of Environmental Health Sciences, 2014)
Background: Extreme weather and air pollution are associated with increased cardiovascular risk in people with diabetes. Objectives: In a population with diabetes, we conducted a novel assessment of vascular brachial artery ...
• Chronic effects of temperature on mortality in the Southeastern USA using satellite-based exposure metrics ﻿

(Nature Publishing Group, 2016)
Climate change may affect human health, particularly for elderly individuals who are vulnerable to temperature changes. While many studies have investigated the acute effects of heat, only a few have dealt with the chronic ...
• Development of Satellite-Based Emission Inventories and Indoor Exposure Prediction Models for PM2.5 ﻿

(2016-09-28)
Epidemiological studies have documented significant relationships between outdoor particle exposure and adverse health effects whilst indoor residential PM2.5 exposure is found to be the most influential on total PM2.5 ...
• Effects of particulate matter exposure on blood 5-hydroxymethylation: results from the Beijing truck driver air pollution study ﻿

(Taylor & Francis, 2015)
Previous studies have reported epigenetic changes induced by environmental exposures. However, previous investigations did not distinguish 5-methylcytosine (5mC) from a similar oxidative form with opposite functions, ...
• Epigenetic Influences on Associations between Air Pollutants and Lung Function in Elderly Men: The Normative Aging Study ﻿

(NLM-Export, 2014)
Background: Few studies have been performed on pulmonary effects of air pollution in the elderly—a vulnerable population with low reserve capacity—and mechanisms and susceptibility factors for potential effects are unclear. ...
• Estimating Causal Effects of Local Air Pollution on Daily Deaths: Effect of Low Levels ﻿

(National Institute of Environmental Health Sciences, 2016)
Background: Although many time-series studies have established associations of daily pollution variations with daily deaths, there are fewer at low concentrations, or focused on locally generated pollution, which is becoming ...
• Estimating Ground-Level PM2.5 in the Eastern United States Using Satellite Remote Sensing ﻿

(American Chemical Society, 2005)
An empirical model based on the regression between daily PM2.5 (particles with aerodynamic diameters of less than 2.5 μm) concentrations and aerosol optical thickness (AOT) measurements from the multiangle imaging ...
• Estimating Regional Spatial and Temporal Variability of PM2.5 Concentrations Using Satellite Data, Meteorology, and Land Use Information ﻿

(National Institute of Environmental Health Sciences, 2009)
Background: Studies of chronic health effects due to exposures to particulate matter with aerodynamic diameters ≤ 2.5 μm (PM2.5) are often limited by sparse measurements. Satellite aerosol remote sensing data may be used ...
• Exposure Characterization and Prediction of Ambient Particulate Matter: From Boston to the Middle East ﻿

(2016-05-03)
Chapter one of this manuscript identifies the sources, composition, and temporal variability of fine (PM2.5) and coarse (PM2.5-10) particles. A Harvard Impactor was used to collect daily particle samples from 2002-2010 at ...
• Exposure to sub-chronic and long-term particulate air pollution and heart rate variability in an elderly cohort: the Normative Aging Study ﻿

(BioMed Central, 2015)
Background: Short-term particulate air pollution exposure is associated with reduced heart rate variability (HRV), a risk factor for cardiovascular morbidity and mortality, in many studies. Associations with sub-chronic ...
