With supplemental financial support from foundations and international organizations, HEI has worked carefully for many years to extend its work in the United States to Europe, where science is often directly relevant to the U.S., and to the developed world, to provide credible, policy relevant science and capacity building to inform air quality decisions in the developing nations of Asia and Latin America.
HEI has attracted significant additional support for its international work from foundations, international organizations, the European Union and industry. In Europe, for example, HEI worked in partnership with WHO on Air Quality Guidelines, and with the European Union on multi-investigator studies of air pollution and health in North America and Europe (APHENA). In Asia, with added support from domestic and international foundations, HEI implemented the Public Health and Air Pollution In Asia (PAPA) program (see several research reports and a comprehensive review comprehensive review of the Asian literature on air pollution and health). We have also conducted the first major multi-country, multi-investigator studies in Latin America (ESCALA). Additional studies in countries outside the US are funded through our competitive research selection process.
This study is performing extensive measurements at different building heights (both outdoors and indoors) in canyon streets with high buildings to develop a three-dimensional land-use regression model for Hong Kong residents.
This study will investigate mortality effects of low levels of air pollution in Canada using Canadian Census data from about 6 million people. The shape of the exposure-response function will be characterized using newly developed flexible non-linear exposure-response functions.

This study will investigate health effects of low levels of air pollution in Europe using pooled data from 10 ESCAPE cohorts with individual covariate information, and 6 large administrative cohorts with less detailed information; resulting in a study population of about 25 million people.

This New Investigator Award study uses portable, real-time sensors to assess misclassification associated with surrogate measures of exposure in a panel of participants that live close to, or far from, traffic and have electric or gas cook stoves. The focus is on ultrafine particles, PM2.5, black carbon, and NO2.
This study is characterizing vehicle emission in two tunnels with different proportions of diesel and gasoline vehicles, measuring fleet average emission factors for a number of pollutants and comparing the results to previous tunnel studies.
