Characterization and Mechanisms of Chromosomal Alterations Induced by Benzene in Mice and Humans

June 2001
Research Report 103

Dr. Eastmond and colleagures at the University of California, Riverside investigated whether chromosomal changes could be used as biomarkers of benzene exposure in mice and humans. The first part of the study involved detecting chromosomal alterations in cells using a modification of a molecular cytogenetic technique known as fluorescence in situ hybridization (FISH). Eastmond and colleagues evaluated the frequency of such chromosomal aberrations in the erythrocytes (red blood cells) from the bone marrow of mice exposed to various doses of benzene and for different exposure durations.

Airborne Particles and Health: HEI Epidemiologic Evidence

Health Effects Institute
June 2001
Perspectives 1

Perspectives 1 is the first of a series produced by the HEI Health Review Committee to integrate findings across several HEI studies or entire research programs. The intent is to describe and interpret results bearing on important and timely issues for a broad audience in terested in environmental health.

Metabolism of Ether Oxygenates Added to Gasoline

May 2001
Research Report 102

The three research projects contained in this report were initiated to increase our knowledge of the metabolism of ether oxygenates in humans and other species. Adding oxygenates, such as MTBE (methyl tert-butyl ether), to gasoline promotes more efficient combustion and reduces emission of carbon monoxide, ozone-forming hydrocarbons, and some air toxics, by increasing the oxygen content of the fuel. On the other hand, some oxygenates may increase emission of toxic compounds such as formaldehyde or acetaldehyde, and increased use of MTBE in fuel in the early 1990s led to complaints of unpleasant odor, headaches, and burning of eyes and throat. The studies were conducted by Dr Jun-Yan Hong (the University of Medicine and Dentistry of New Jersey – Robert Wood Johnson Medical School), Dr Wolfgang Dekant (University of Würzburg), and Dr Janet Benson (Lovelace Respiratory Research Institute).

Respiratory Epithelial Penetration and Clearance of Particle-Borne Benzo[a]pyrene

Research Report 101

Dr. Gerde and colleagues at the Lovelace Respiratory Research Institute examined the effects of organic compounds in diesel exhaust such as genotoxic polynuclear aromatic compounds (PAHs). The investigators removed most of the organic compounds from diesel exhaust particles and bound radioactive Benzo[a]pyrene (BaP), a type of PAH is known to cause cancer in laboratory animals, to them. They exposed the lower respiratory tract of three dogs to the particles and measured the levels of particle-bound BaP and free BaP released from particles in the peripheral region of the lungs.

Respiratory Tract Toxicity in Rats Exposed to Mexico City Air

Research Report 100

Dr. Moss of CIIT evaluated the effects of rats exposed to ambient air in a highly polluted area in southwestern Mexico City. Pathologists have found evidence of cell damage and inflammation in nasal tissue from some human residents of this highly polluted area that was not present in people living in areas of the country with cleaner air and this study sought to determine if those effects could be replicated in rats.

A Case-Crossover Analysis of Fine Particulate Matter Air Pollution and Out-of-Hospital Sudden Cardiac Arrest

December 2000
Research Report 99

Dr Checkoway and colleagues at the University of Washington tested the primary hypothesis that increases in daily fine particle levels were related to increased risk of out-of-hospital sudden cardiac arrest. Sudden cardiac arrest and questionnaire data, and exposure data were obtained from the Puget Sound Clean Air Agency (Seattle WA). The investigators used a case-crossover study design; for each case of sudden cardiac arrest, a time period when the person was disease free was selected as a matched "referent" period.

Daily Mortality and Fine and Ultrafine Particles in Erfurt, Germany. Part I: Role of Particle Number and Particle Mass

November 2000
Research Report 98

Dr H-Erich Wichmann and colleagues at the National Research Center for Environment and Health in Germany prospectively studied the association of daily mortality data with the number and mass concentrations of ultrafine and fine particles in Erfurt, Germany. Concentrations were measured near a road and a time-series approach was used to look at short-term changes in particle concentration and concurrent deaths due to cardiovascular and respiratory causes over a period of 3.5 years.

Identifying Subgroups of the General Population That May Be Susceptible to Short-Term Increases in Particulate Air Pollution: A Time-Series Study in Montreal, Quebec

Research Report 97

Dr. Mark Goldberg and his colleagues at McGill University conducted a time-series study in Montreal using available data from the Quebec Health Insurance Plan and mortality and air pollution data to better the understanding of the mortality-particulate association. Because of the comprehensive nature of this health insurance database, the investigators were able to link individual deaths in Montreal to medical information up to 5 years before death.

Association of Particulate Matter Components with Daily Mortality and Morbidity in Urban Populations

August 2000
Research Report 95

Dr Morton Lippmann and colleagues at the New York University School of Medicine attempted to identify and characterize components of PM and other air pollution mixtures that were associated with excess daily deaths and elderly hospital admissions in and around the area of Detroit, Michigan. Using publicly available data from 1985-1990 and 1992-1994, the investigators used statistical models to weigh the strength of one pollutant or two pollutants concurrently.
