This report describes a study that tested whether an air toxics "hot spot" existed in Camden, NJ. Dr. Lioy and colleagues evaluated ambient and personal exposures of nonsmoking residents to PM2.5, VOCs, aldehydes, and PAHs in two neighborhoods in Camden, NJ, one of which was hypothesized to be a regional air toxics "hot spot." The investigators compared concentrations of air pollutants in the two neighborhoods with each other and then with concentrations at other locations in the United States. They also assessed the effects of seasonality, contributions from mobile sources, and spatial variability.

This report contains studies in Chennai and Delhi led by Dr. Kalpana Balakrishnan and Dr. Uma Rajarathnam, respectively. These time-series studies of air pollution and mortality in India were funded under HEI's PAPA Program to provide information to inform regulatory and other decisions that would be relevant to local populations, with the added goal of supporting scientific capacity building in the region.

This report investigates methods with the high sensitivity and low limits of detection needed to analyze a wide range of chemical species in particulate matter collected with personal samplers. Dr. Schauer and colleagues developed sensitive methods to detect trace metals, nonpolar organic compounds, and polar organic compounds in personal samples collected in exposure studies. Methods used in this study are of interest to researchers seeking to gain greater insight into the relationships between the components of inhalable particulates and their health effects.

This report describes the first set of coordinated time-series studies ever undertaken in Asian cities: four time-series studies of the health effects of air pollution in Bangkok, Hong Kong, Shanghai, and Wuhan. These studies were intended to help bridge the gaps between studies conducted in different locations around the globe.

This report describes a unique collaboration among investigators from Europe, the United States, and Canada using existing data from three geographic areas and supported by HEI in collaboration with the European Commission. APHENA offered a large and diverse data set with which to address methodological as well as scientific issues about the relationships between PM10, ozone, and mortality and morbidity that were the subject of lively debates at the time the project was launched.

This report describes a recent analysis of the original ACS cohort, a large ongoing prospective study of mortality in adults that started in 1982 and has played a central role in the setting of National Ambient Air Quality Standards for fine particulate matter pollution in the U.S. as well as assessments of benefits from PM reduction worldwide. The new study describes for the first time work by Dr.

This report describes a study to explore novel electrocardiogram (ECG) parameters to improve our understanding of how air pollution may affect cardiovascular health. Drs. Robert Lux and Arden Pope used ECGs obtained in a previous study by Dr. Pope that found a decrease in heart rate variability associated with increased levels of particulate matter, and analyzed them for changes in novel parameters of another important potential change - ventricular repolarization.

Research Report 139 describes a study in the Netherlands using data from the ongoing Netherlands Cohort Study (NLCS) on diet and cancer. The study is one of the first to systematically assess longer term exposure and mortality in a well characterized European population; it followed a pilot study of 5000 adults randomly selected from the NLCS cohort conducted by the same team of investigators. For the current study, Dr.

Research Report 138, Health Effects of Real-World Exposure to Diesel Exhaust in Persons with Asthma, is one part of HEI's larger program on the role of particles in exacerbating asthma and other allergic diseases. This report describes a study to evaluate how inhaling air with a high concentration of diesel exhaust from vehicular traffic while walking on a busy street in Central London might affect people who had either mild or moderate asthma. Dr.

Research Report 136, Uptake and Inflammatory Effects of Nanoparticles in a Human Vascular Endothelial Cell Line, is one part of HEI's larger program on the health effects of particulate matter and its various components. This report describes a one-year study to evaluate which physicochemical characteristics of metal nanoparticles may contribute to their toxicity.
