Tens of thousands of unknown chemicals surrounds us. 

The research looked at how two different types of plastic break down when tested in extreme conditions.

New science has taken a deep dive into plastic waste, providing the first estimate of how much ends up on the sea floor.

California, a state known for its aggressive greenhouse gas reduction policies, is ironically the nation's greatest emitter of one: sulfuryl fluoride.

An extensive CO2 monitoring network set up around the San Francisco Bay Area by an atmospheric chemist from the University of California, Berkeley, has recorded the first evidence that the adoption of electric vehicles is measurably lowering the area's carbon emissions.

Soil contains about twice as much carbon as the atmosphere and plants combined.

A research team led by the University of Massachusetts Amherst, in collaboration with the University of Alaska-Anchorage and Columbia University, has conducted the widest-ever hydrological tracer analysis of the Dry Andes region in Chile, Argentina and Bolivia, home to the majority of the world’s lithium deposits and other elements, such as copper, critical to the green energy transition away from oil and toward electricity.

In the largest and most comprehensive assessment to date of hundreds of U.S. landfills, scientists from Arizona State University, who are part of a research collaboration with Carbon Mapper, have discovered that many landfills in the U.S. are releasing high volumes of methane and are responsible for a disproportionately large share of pollution from this important sector.

Arsenic is a toxic metalloid of natural origin. Arsenic-contaminated soils and waters are found all over the world, especially in southeastern Asian countries like Bangladesh, Vietnam, and China.

Researchers at McGill University have come up with an innovative approach to improve the energy efficiency of carbon conversion, using waste material from pulp and paper production.
