Coal-fired power plants are a major source of mercury contamination for people and the environment. Here's what you need to know.

Mercury's tenuous neutral atmosphere—a surface-based exosphere—was shown by MESSENGER to vary seasonally with the planet's changing solar distance over the course of a Mercury year.

Elemental mercury (Hg0) is a toxic air pollutant that can travel long distances and circulate globally. Scientists have long suspected that today's ...

The melting of permafrost in the Arctic could result in toxic mercury leaching into the waters of Alaskan rivers, putting millions of people at risk. This "giant mercury bomb" lurks within the soils ...

A recent breakthrough in planetary science reveals the first-ever detection of lithium in Mercury’s exosphere—a result achieved not through traditional particle observation, but through a novel method ...

Permafrost covers roughly 25 percent of exposed land surface in the Northern hemisphere, and it plays a vital role in locking away carbon and toxic metals like mercury. A new study says that a looming ...
