US Environmental Protection Agency (EPA) is awarding $25m to the Health Effects Institute (HEI) for improving the air quality and protecting health.

With the funding, HEI will develop the next generation of tools and scientific information to examine the combined effects of air pollution exposures on people’s health and the relationship between air quality and climate change.

EPA reported that over the past 30 years, the partnership has made significant contributions to protecting health from air pollution.

EPA Office of Research and Development assistant administrator Paul Anastas said that this grant continues a long and fruitful partnership to address air quality issues.

"The scientific contributions by HEI complement and augment EPA’s extensive clean air research program, which is providing the critical science needed to improve air quality," Anastas said.

HEI is a non-profit research organization that provides impartial science to help address air quality problems in the nation.
