Americans spend about 90% of their time indoors, where air quality levels can decline simply because of someone’s presence, the products used inside or the activities undertaken there, according to experts on indoor air chemistry.

Editors of leading peer-reviewed scientific journals published on Monday a joint response to a proposed EPA rule.

Chemicals in consumer products like soaps and paints contribute as much as car emissions do to air pollution, a new study in the journal Science reports.

Lin Zheng, a leading Chinese communications professional, traveled earlier this spring from Beijing to Wuhan, an ancient city with a growing scientific presence, to address a group of media officers eager to improve their science communication skills.

Tracey Holloway believes stakeholders should be part of the research process itself. That’s why for more than a decade, she has not only shared her air quality data with city, state and federal agencies who manage air pollution, she asks for their input on research projects as they are evolving. She wants to ensure her work “fills the gaps between existing science and stakeholders’ needs,” and isn’t just “scientists speaking to scientists.” These partnerships have been fruitful for Holloway, who says nearly all of her research contains some elements inspired by the air quality managers she works with.
