Researchers from Nagoya University in Japan have reported that nitrate accumulated in soil bordering streams plays an important role in the increase of nitrate levels in stream water when it rains.

An analysis of sediments from five North Carolina lakes near coal-burning power plants has found that coal ash pollution of surface waters has been more persistent and widespread than was previously known.

Scientists from the University of Illinois Urbana-Champaign, University of California, Santa Barbara, and Dow have developed a breakthrough process to transform the most widely produced plastic — polyethylene (PE) — into the second-most widely produced plastic, polypropylene (PP), which could reduce greenhouse gas emissions (GHG).

Developing countries should focus on keeping unnecessary occupants, such as children, out of kitchens during cooking to help reduce their exposure to dangerous levels of air pollution, recommends a study by the University of Surrey.   

Oil and gas producers rely on flaring to limit the venting of natural gas from their facilities, but new research led by the University of Michigan shows that in the real world, this practice is far less effective than estimated—releasing five times more methane in the U.S. than previously thought.

In July, purple and pink hues painted the Antarctica and New Zealand skies — likely the result of atmospheric particles called aerosols that belched into the stratosphere in January during the eruption of the Hunga Tonga-Hunga Ha'apai volcano.

Turning plastic waste into useful products through chemical recycling is one strategy for addressing Earth's growing plastic pollution problem.

The researchers studied a colony of emperor penguins in Atka Bay, a remote area on the northeastern edge of the Ekström Ice Shelf.

“This lake wasn’t here 50 years ago.” 

Propylene is a gas used to make a large variety of packaging and containers and is considered to be the second most important starting product in petrochemical engineering.
