Indoor air pollution

In 1976, beloved chef, cookbook author and television personality Julia Child returned to WGBH-TV’s studios in Boston for a new cooking show, “Julia Child & Company,” following her hit series “The French Chef.” Viewers probably didn’t know that Child’s new and improved kitchen studio, outfitted with gas stoves, was paid for by the American Gas Association. While this may seem like any corporate sponsorship, we now know it was a part of a calculated campaign by gas industry executives to increase use of gas stoves across the United States. And stoves weren’t the only objective. The gas industry wanted to grow its residential market, and homes that used gas for cooking were likely also to use it for heat and hot water. The industry’s efforts went well beyond careful product placement, according to new research from the nonprofit Climate Investigations Center, which analyzes corporate efforts to undermine climate science and...

Humans have contended with dust storms for thousands of years, ever since early civilizations appeared in the Middle East and North Africa. But modern desert dust storms are different from their preindustrial counterparts. Around the world, deserts now increasingly border built structures, including urban dwellings, manufacturing, transportation hubs, sewage treatment and landfills. As a result, desert dust lifts a growing load of airborne pollutants and transports these substances over long distances. This is happening throughout the Global Dust Belt, an arid to semiarid region that stretches from western China through Central Asia, the Middle East and North Africa. Similar storms occur in the U.S. Southwest and central Australia. Global pattern of dust frequency estimated from weather records, 1974-2012. Shao et al., 2013, CC BY-ND To our thinking, modern desert dust storms have been overlooked...

The Research Brief is a short take about interesting academic work. The big idea Consumer products released more than 5,000 tons of chemicals in 2020 inside California homes and workplaces that are known to cause cancer, adversely affect sexual function and fertility in adults or harm developing fetuses, according to our newly published study. We found that many household products like shampoos, body lotions, cleaners and mothballs release toxic volatile organic compounds, or VOCs, into indoor air. In addition, we identified toxic VOCs that are prevalent in products heavily used by workers on the job, such as cleaning fluids, adhesives, paint removers and nail polish. However, gaps in laws that govern ingredient disclosure mean that neither consumers nor workers generally know what is in the products they use. For this study we analyzed data from the California Air Resources Board (CARB), which tracks VOCs released from consumer products in an effort to reduce smog. The agen...
