This unpublished research report describes a two-year study aimed at building and testing a method for the semi-continuous measurement of reactive oxidant species (ROS) generated by particulate matter in a cellular assay. The assay relied on the use of a compound that turns into a fluorescent product upon reaction with ROS generated in the cells.

This newsletter reports on the approval of new HEI studies to examine potential health effects of low-level pollution; the completion of a review of diesel exhaust studies (Special Report 19) by an HEI-appointed panel; and WHO's plans to update global air quality guidelines. In addition, it announces the publication of an HEI report taking a closer look at exposure to PM2.5 and its composition and a report evaluating rapid heart rhythm changes after exposure to PM. HEI also announces the recipient of the 2015 Walter A. Rosenblith New Investigator Award and the appointment of three new HEI Research Committee members.

This unpublished report describes a two-year study to evaluate the effect of exposure to particulate matter and ozone on immune function in nonhuman primates (infant rhesus macaques) during early life. The investigators conducted a panel study that took advantage of "natural" exposures in the outdoor nonhuman primate colony maintained at the California National Primate Center, a research unit of the University of California–Davis.

October 2012

This report describes the first-ever multicity study to estimate the effect of short-term exposures to particulate matter (PM10) and to ozone on mortality in nine Latin American cities. Led by Dr. Isabelle Romieu in Mexico, in collaboration with Dr. Nelson Gouveia in Brazil and Dr. Luis Cifuentes in Chile, the researchers evaluated mortality from all causes and in different age groups, using a common analytic framework. They analyzed mortality in each city and the region as a whole, and explored two pollutant models in individual cities. They also used two meta-analytic statistical techniques to further analyze the effects from individual cities.

This report is the latest in HEI's program of studies to assess the health impacts of air quality actions. Research Report 148 describes a study to evaluate the effect of a short-term, temporary intervention to reduce traffic congestion during the 1996 Summer Olympic Games in Atlanta, Georgia. A previous study had shown a decrease in acute care visits for pediatric asthma and a concomitant decrease in concentrations of ozone, particulate matter, and carbon monoxide.

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. 

Communication 13
Health Effects Institute
October 2008

The September issue of Environmental Health Perspectives published the first systematic presentation of the HEI-funded PAPA studies in Bangkok, Hong Kong, Shanghai, and Wuhan, as well as a combined analysis and accompanying editorial. These articles have been reprinted and are currently available as HEI Communication 13. The detailed studies and accompanying HEI commentaries will be published by the Institute this spring.
