HEI publishes report on mutagenicity of butadiene metabolites – June 2010
Research Report 150, Mutagenicity of Stereochemical Configurations of 1,3-Butadiene Epoxy Metabolites in Human Cells, describes a study by Dr. Ryan Meng and colleagues to determine the role of stereochemistry in the cytotoxicity and mutagenicity of three major butadiene metabolites. This study is a part of HEI’s program of research on air toxics; one important aim of that program has been to fill key gaps in risk assessment for some of the most important chemicals. Butadiene is present in motor vehicle exhaust and other emissions and is listed by the U.S. Environmental Protection Agency among the mobile-source air toxics that, because of their emissions and reported toxicity, pose a possible health risk. The study addressed a key research and risk assessment question related to species differences in tumor induction by butadiene, which have been attributed to differences in its metabolism. The investigators evaluated whether different stereoisomers (spatially different forms of the same chemical structure) of the metabolites showed different levels of mutagenicity in a human lymphoblastoid cell line.

HEI publishes report on a sensitive method to measure acrolein – May 2010
Research Report 149, Development and Application of a Sensitive Method to Determine Concentrations of Acrolein and Other Carbonyls in Ambient Air, describes a study by Dr. Thomas Cahill and colleagues to create and evaluate a new method to measure acrolein and other volatile carbonyls present at low concentrations in ambient air. Acrolein is an important aldehyde that is very difficult to measure accurately, so developing better methods for measuring levels and exposure is critical to better risk assessment for the chemical. The investigators developed a sampler that traps acrolein using sodium bisulfite in an aqueous medium. The study included a field test near an area of heavy traffic, which allowed investigators to compare the results of their method with those from conventional methods.

HEI launches Strategic Plan 2010-2015 – April 2010
HEI has launched its Strategic Plan for the coming five years, guiding HEI’s direction based on extensive input from sponsors, the scientific community, environmental organizations and others. The Plan seeks to produce timely and credible science to inform key decisions with an important principal overarching theme: to develop and apply next-generation multipollutant approaches to understanding exposure to and health effects of air pollutants. The four core programs are: multipollutant exposure, epidemiology, and toxicology; emerging fuels and technologies; health impacts of air quality actions (accountability); and an international perspective. HEI will pursue these research topics both for conventional air pollutants and at the nexus of air quality and climate.

HEI also expects to infuse important cross-cutting issues into all that it does, including the effects of air pollution in sensitive populations; innovation in statistics, new toxicology, and related areas; and a continued focus on validation of whether existing and new biologic techniques and statistical analyses well represent actual exposures and health effects.

HEI publishes report on improved air quality during the Atlanta Olympic Games – April 2010
Research Report 148, Impact of Improved Air Quality During the 1996 Summer Olympic Games in Atlanta on Multiple Cardiovascular and Respiratory Outcomes, 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. Because it was not clear to what extent normal seasonal patterns in pollutant concentrations or health outcomes may have influenced the results, Dr. Peel and colleagues evaluated wider time windows surrounding the Olympic Games period and extended the analyses to earlier and later years and to broader geographic areas. They also evaluated additional respiratory and cardiovascular health outcomes in adults.

HEI publishes report on atmospheric transformation of diesel exhaust – May 2010
Research Report 147, Atmospheric Transformation of Diesel Emissions, describes a study by Dr. Barbara Zielinska and colleagues to investigate the changes that fresh diesel emissions undergo when they are mixed with ambient air, due to reactions with sunlight and other pollutants. The investigators also evaluated how those changes may affect the toxic properties of diesel emissions. The study used a relatively new (2003 model) light duty diesel engine (although not one with a diesel filter) and provides insight into the complexity of diesel exhaust composition in the real world.

HEI issues Request for Applications on ozone-PM – February 2010
HEI has issued RFA 10-1: Cardiovascular Effects of Exposure to Low Levels of Ozone in the Presence or Absence of Other Ambient Pollutants. Two types of studies are sought to evaluate cardiovascular and respiratory effects in healthy human volunteers, aged 55 and above. In Phase 1, volunteers will be exposed to ozone alone, at concentrations between 60 and 100 ppb, in a controlled laboratory setting. In Phase 2, volunteers will be exposed to real-world ambient air pollution at sites with ozone concentrations comparable to those used in Phase 1. Letters of Intent are due on March 29, 2010; applications will be due on May 6, 2010. Please refer to the Funding page for the full text of the RFA and information on how to apply.
 
HEI publishes Annual Report for 2009 – February 2010
The 2009 Annual Report describes the many strong scientific contributions HEI made this past year to the study of the health effects of air pollution and reports on the vision mapped out by our new Strategic Plan. Read more about HEI's accomplishments and future goals in the 2009 Annual Report, Making a Difference for Today and Tomorrow.
 
 
HEI publishes Special Report on the health effects of traffic-related air pollution – January 2010
HEI's Special Report 17, Traffic-Related Air Pollution: A Critical Review of the Literature on Emissions, Exposure, and Health Effects, is the most comprehensive and systematic review to date of the scientific literature on emissions, exposure, and health effects from traffic-related air pollution. It includes conclusions about the populations exposed around major roads, the associations between exposure to air pollution from traffic and human health, and important remaining data gaps. Compared with the initial pre-print version released in May 2009, this final version has undergone data verification and editorial changes; however, the overall conclusions did not change.
