The particulate matter in the atmosphere can result in poor air quality and visibility, posing a risk to human health and transportation safety.

As concern grows among environmentalists and consumers about micro- and nanoplastics in the oceans and in seafood, they are increasingly studied in marine environments, say Baoshan Xing at the University of Massachusetts Amherst and colleagues in China. 

Rice University engineers have created a light-powered catalyst that can break the strong chemical bonds in fluorocarbons, a group of synthetic materials that includes persistent environmental pollutants.

A U.S. Department of Energy-funded collaborative project will allow Texas A&M AgriLife researchers to measure greenhouse gas emmissions from agricultural fields in the Southern Great Plains.

The researchers did not find differences in PM2.5 exposures based on trip length, which might not be reflective of factors like traffic volume that impact exposures.

A team of researchers, led by Professor Gavin Shaddick at the University of Exeter, has shown that, despite global efforts to improve air quality, vast swathes of the world’s population are experiencing increased levels of air pollution.

Infographics strive to give us a sense of how long plastic goods will last in the environment. But is this information reliable?

Picture 500 million cars stacked in rows. That’s how much carbon—about 1,000 petagrams, or one billion metric tons—is locked away in Arctic permafrost.
