At its Annual Conference in Seattle on May 7, HEI is presenting its draft Strategic Plan for 2020-2025

Study examines toxicity of aerosol mixtures derived from isoprene

April 8, 2019

HEI has published Research Report 198, which describes a study by Dr. Jason Surratt and his colleagues to evaluate the toxicity of fine particulate matter formed from the photochemical oxidation of isoprene in smog-chamber facilities.

Study examines oxidative properties of ambient PM and laboratory-generated organic aerosols

April 5, 2019

HEI has published Research Report 197, which describes a study by Dr. Nga (Sally) Ng and her colleagues to characterize and compare the oxidative properties of ambient particulate matter and laboratory-generated secondary organic aerosols in toxicological assays.

Study examines real-world emissions characterization in two traffic tunnels

March 26, 2019

HEI has published Research Report 199, which describes a study led by Dr. Xiaoliang Wang at the Desert Research Institute in Reno, Nevada. Wang and his colleagues sought to evaluate how mobile-source emissions have changed through real-world emission characterization in two traffic tunnels: the Shing Mun Tunnel in Hong Kong and the Fort McHenry Tunnel in Baltimore, Maryland.

HEI requests proposals to improve assessment of long-term exposure to air pollution

March 15, 2019

HEI has issued Request for Applications (RFA) 19-1: Applying Novel Approaches to Improve Long-Term Exposure Assessment of Outdoor Air Pollution for Health Studies. HEI is seeking to fund studies to advance exposure assessment for air pollution and health studies using sensors, mobile monitoring, tracking technologies, and other approaches, with a focus on improving assessment of long-term exposures. Please refer to our Funding page for details. 

Winter 2019 Update now available

February 20, 2019

In this issue of Update, read about a major new HEI study that measured progress on air quality in traffic tunnels, as well as two new HEI studies that examined secondary organic aerosols. Also in this edition, read about how we’re building our Strategic Plan for 2020–2025, our upcoming Annual Conference in Seattle, Washington, and more.
