Particulate Matter

Special Report 22 describes a study led by a team of investigators from Fudan and Tsinghua Universities, other Chinese research institutions, and HEI scientists Allison Patton and Katherine Walker, as part of HEI’s Global Health Program. The report provides an analysis of emissions from shipping and related activities and their impacts on air quality and health in the Yangtze River Delta and Shanghai.

In this issue of Update, read about HEI’s publication of two major reports evaluating the extent to which air pollution at low levels of exposure may have consequences for public health; a revised draft of our Strategic Plan for 2020–2025; a new epidemiologist appointed to the HEI Review Committee; the communication of HEI research at important government, industry, and scientific conferences; and more.

Research Report 200 describes the first-phase results of a study examining any association between exposure to low levels of air pollution — both PM_2.5 and O₃ — and all-cause mortality in a population of 61 million Medicare enrollees residing in the continental United States. The report also presents the detailed Commentary on the study by HEI’s Low-Exposure Epidemiology Studies Review Panel.

Communication19 describes a study led by HEI’s Ghana Working Group evaluating the contribution of household air pollution to ambient fine particle air pollution in Ghana, as well as its impact on health.
