2010

This report explores how land-use regression and source-apportionment techniques can be used to characterize individual-level exposure to both indoor and outdoor air pollution sources. Dr. Levy and colleagues utilized health and air monitoring data from an ongoing prospective cohort study on childhood asthma in Boston, Massachusetts to model variability in outdoor and indoor residential air pollution, identify potential sources, and evaluate the effectiveness of various indoor exposure surrogates for predicting childhood asthma development.

HEI Communication 12 describes a project by Dr Scott Zeger and colleagues at the Johns Hopkins Bloomberg School of Public Health that was funded by HEI to make data and software from the National Morbidity, Mortality, and Air Pollution Study (NMMAPS) available to the wider research and policy communities. This Communication contains the Project Report, which describes the Internet-Based Health and Air Pollution Surveillance System (iHAPSS), along with Comments from some members of the HEI Health Research and Review Committees and other experts who had used the data.

Research Report 123
Francesca Dominici
2004

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.

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.

2004

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.

Special Report
Health Effects Institute
2003

Over the past decade, time-series studies conducted in many cities have contributed information about the association between daily changes in concentrations of airborne particulate matter (PM) and daily morbidity and mortality. In 2002, however, investigators at Johns Hopkins University and at Health Canada identified issues in the statistical model used in the majority of time-series studies. This HEI Special Report details attempts to address several questions raised by these discoveries.

2003

Dr. Susanne Hering of Aerosol Dynamics Inc and her colleagues set out to design and validate a personal monitoring sampler for particles smaller than 2.5 µm (PM2.5) that is suitable for subsequent chemical speciation work. The sampler intended to meet the measurement needs for PM2.5 mass concentration and several of its major constituents including elemental carbon, organic carbon, sulfates, and nitrates.

2000

In an effort to address the uncertainties regarding the association between PM and daily mortality, and to determine the effects of other pollutants on this association, HEI funded the National Morbidity, Mortality, and Air Pollution Study (NMMAPS). Dr Jonathan Samet and his colleagues at Johns Hopkins University, in collaboration with investigators at Harvard University, conducted this time-series study in large cities across the US where levels of PM and gaseous pollutants were varied.

Research Report 86
William Navidi
Duncan Thomas
Bryan Langholz
Daniel Stram
1999

Dr. Navidi and colleagues at the University of Southern California discussed the development of three sophisticated statistical methods that would improve the estimates of the health effects of air pollution obtained from epidemiologic studies. First, they took a standard case-crossover design and introduced a bidirectional element where control data were obtained both before and after the health event of interest.

Research Report 81
Ira B Tager
Patrick L Kinney
1998

Dr. Ira Tager and colleagues at the University of California at Berkeley (UCB), and Dr. Patrick Kinney and colleagues at the School of Public Health, Columbia University objectives were to develop new methods for estimating an individual's past exposure to ozone.
