HEI launches Strategic Plan for 2015-2020 – May 2015 NEW


stategic plan

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 one overarching theme: informing decisions on air quality and on climate-driven technology for 2015-2020…and beyond. The four core program elements are addressing the continuing challenges of multipollutant science; improving science for decisions through accountability and transparency; assessing emerging fuels and technologies; and addressing global health issues. HEI also expects to infuse important cross-cutting issues into all that it does. To download the Plan, click here PDF.


HEI Winter Update now available – February 2015



The Winter Update newsletter features the release of a major report that found no evidence of lung cancer in rats after lifetime exposure to new-technology diesel exhaust, and registration information for HEI’s exciting upcoming Annual Conference in Philadelphia this May. Also read about progress on the strategic plan by the Committee on 21st Century Oil and Gas Development, highlights from the Better Air Quality meeting in Sri Lanka, and a request for nominations for membership of HEI's Research and Review Committees.

HEI Annual Report now available – February 2015


annual report

The 2014 Annual Report describes HEI’s partnership with scientists, government, industry, and the environmental community to provide high-quality, impartial, and relevant science to inform public policy decisions about air quality and public health. The report outlines HEI’s contributions in the past year to important questions posed by government and industry, including whether some sources of particles are more or less toxic than others, whether emissions from new-technology diesel engines are less harmful than those from older engines, and what global effects air pollution has on years of healthy life lost.To download the report, click here.


HEI report on lifetime animal exposure to new-technology diesel engine exhaust finds no evidence of lung cancer – January 2015


report 184

Research Report 184, Advanced Collaborative Emissions Study (ACES): Lifetime Cancer and Non-Cancer Assessment in Rats Exposed to New-Technology Diesel Exhaust, describes the first study to conduct a comprehensive evaluation of lifetime exposure to new-technology diesel exhaust (NTDE). The study was conducted by Drs. Jacob McDonald of the Lovelace Respiratory Research Institute, Jeffrey Bemis of Litron Laboratories, Lance Hallberg of the University of Texas Medical Branch, and Daniel Conklin of the University of Louisville, and their colleagues. Male and female rats were exposed for 80 hours per week, for up to 30 months, to emissions from a heavy-duty diesel engine meeting stringent 2007 U.S. standards that has greatly reduced particle emissions compared with pre-2007 engines. The investigators evaluated more than 100 different biologic endpoints, including tumor development, and compared the results with biologic effects seen in earlier studies in rats exposed to diesel exhaust from pre-2007 engines.

HEI Special Scientific Committee hosts second workshop following the release of its draft interim report – December 2014  
Special Scientific Committee on Unconventional Oil and Gas

Click here for more information
The HEI Special Scientific Committee on Unconventional Oil and Gas Development hosted its second in a series of three workshops on the potential impacts of 21st century oil and gas development in the Appalachian Basin. Workshop participants from academia, industry, government, and non-governmental organizations heard from speakers knowledgeable about potential impacts on communities and trends in oil and gas industry practice and technology. The workshop was timed to allow for participant feedback on the Committee’s draft interim report - The Potential Impacts of 21st Century Oil and Gas Development in the Appalachian Basin: First Steps Toward a Strategic Research Plan PDF and to receive input regarding research needs and criteria for prioritizing research needs prior to development of the Committee’s final product, the Strategic Research Plan.

HEI publishes report on mechanisms of lung tissue repair after PM exposure – November 2014  
report 182
Research Report 182, Synergistic Effects of Particulate Matter and Substrate Stiffness on Epithelial-to-Mesenchymal Transition, is a study focused on lung tissue repair processes after inflammation and injury resulting from exposure to particulate matter (PM) from combustion sources. Dr. Thomas H. Barker of Georgia Institute of Technology, a recipient of HEI’s Walter A. Rosenblith New Investigator Award, and his colleagues tested the hypotheses that alveolar epithelial cells grown on substrates of increasing stiffness would transition to mesenchymal cells — an early step along the pathway to fibrosis — and that the addition of fine PM would enhance these effects.
