et al.
June 2005

This report contains two studies, by Drs. Annette Peters and Douglas Dockery. Dr. Peters and her colleagues evaluated the association between nonfatal myocardial infarction (MI) and exposure to particulate matter just prior to the event. She asked 691 patients in hospitals in Augsburg, Germany who survived an MI to provide hourly details about their activities 4 days before MI onset. The investigators used a case-crossover analysis to determine whether exposure to pollutants was associated with onset of MI. Dr. Dockery and colleagues assessed the correlation between short-term increases in ambient concentrations of particulate matter and the risk of possibly life-threatening arrhythmias in patients with implanted cardioverter defibrillators (ICDs). The investigators studied 195 patients from Boston, MA who had either single or dual-chamber ICD's and used logistic regression models to determine whether exposure to air pollutants was associated with arrhythmias.

To answer important questions about possible sources of metal exposure from both tailpipe and non-tailpipe emissions, Dr. James Schauer and his colleagues at the University of Wisconsin - Madison collected and characterized metals in fine and coarse particles from a variety of sources, including tailpipe emissions, dust from brake and tire wear, and roadway dust.

Dr. Brunekreef and his colleagues assessed the correlation between personal, indoor, and outdoor PM2.5 concentrations for elderly people with cardiovascular disease living in Amsterdam, The Netherlands, and Helsinki, Finland. Measurements were taken between November 1998 and June 1999 using fixed monitoring sites near the subjects' residences and inside their homes using the same type of monitor. Personal exposures were monitored with a different type of sampler that the subjects kept with them at all times.

Dr. Frampton and his colleagues evaluated the effects of exposing healthy and mildly asthmatic men and women to laboratory-generated ultrafine carbon particles. They hypothesized that ultrafine particle exposure would activate leukocytes and endothelial cells and lead to an inflammatory response in the airway and in the blood; and that it also might affect respiration and cardiac electrophysiologic function. They further hypothesized that effects would be greater in people with asthma than in healthy people.

This report describes a study funded under the Walter A. Rosenblith New Investigator Award. Dr Francesca Dominici and colleagues at Johns Hopkins University developed more flexible methods and statistical models for the National Morbidity, Mortality, and Air Pollution Study database.

November 2004

Dr Alison S Geyh and colleagues at Johns Hopkins University evaluated the personal and microenvironmental aerosol speciation sampler (PMASS) prototype developed by Dr. Susanne Hering with HEI funding (HEI Research Report 114). The precision and accuracy of the prototype, which measures PM2.5 mass, elemental and organic carbon, sulfate, and nitrate, was evaluated in two locations with different PM composition. Baltimore, Maryland (outdoors), and Fresno, California (indoors). Geyh and colleagues set a target of 10% precision and 10% accuracy for all species measured.

Dr. Beverly Cohen and her colleagues at New York University School of Medicine tested the performance of iron nanofilms to collect and measure sulfuric acid particles of different sizes under a variety of temperature and humidity conditions. The iron nanofilm detector is a thin iron-coated silicon chip. Particles would react with the iron, creating an elevated site or bump on the film surface, which can be visualized using an atomic force microscope.

Dr. Jack Harkema and colleagues at Michigan State University conducted a 2-year study with rats to evaluate the short-term effects of inhaling concentrated ambient particles derived from the air in an area of Detroit, Michigan that has a high incidence of childhood asthma. The investigators used two animal models, BN rats that were sensitized with ovalbumin to induce some features of asthma, and F344 rats pretreated with endotoxin to have some features of mild bronchitis. Animals were exposed for 10 hours/day for 1 day or for 4 or 5 consecutive days.

In Part III of the National Morbidity, Mortality, and Air Pollution Study (NMMAPS), Dr. Daniels and colleagues at Johns Hopkins University and Harvard University evaluated the shape of the relation between PM10 concentrations measured at fixed monitoring sites and daily mortality among residents from all causes (excluding accidental causes), from all cardiovascular and respiratory causes combined, and from causes other than cardiovascular-respiratory disease.

Special Report 15
Health Effects Institute
April 2004

A Special Report by the HEI International Scientific Oversight Committee of HEI Public Health and Air Pollution in Asia (PAPA) Program (a program of the Clean Air Initiative for Asian Cities). This first publication to come from HEI's PAPA Program was undertaken to help inform the Clean Air Initiative for Asian Cities. This special report has identified and summarized more than 135 studies of air pollution and health conducted across Asia. In addition, it critically reviews for the first time a key subset of these studies: 28 studies of daily mortality. The report is a valuable resource for policy makers in Asia and beyond.
