Time-Series Analysis of Air Pollution and Mortality: A Statistical Review

Research Report 123

Francesca Dominici

2004

Topics:

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.

Evaluation of a Personal and Microenvironmental Aerosol Speciation Sampler (PMASS)

Research Report 122

Alison S Geyh

Susanne Hering

Nathan Kreisberg

Walter John

2004

Topics:

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 PM_2.5 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.

Field Evaluation of Nanofilm Detectors for Measuring Acidic Particles in Indoor and Outdoor Air

Research Report 121

Beverly Cohen

Maire SA Heikkinen

Yair Hazi

Hai Gao

Paul Peters

Morton Lippmann

2004

Topics:

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.
