Researchers estimated that before humans started pumping mercury into the atmosphere, it contained on average about 580 megagrams of mercury. However, in 2015, independent research that looked at all ...

Mercury levels in yellowfin tuna caught off the coast of Hawaii have not changed in 27 years, despite a considerable increase in atmospheric mercury during this time, according to a new study. The ...

The activity of humans has significantly raised the levels of mercury in the atmosphere. These levels have gone up about seven times since 1500 CE, when the modern era began. A new method was ...

Fires in high-latitude forests and peaty soils of the Northern Hemisphere may loft hundreds of tons of mercury into the atmosphere each year, much more than scientists had expected, a new analysis ...

Over the past decade, high concentrations of mercury contamination have appeared in higher organisms in the Florida Everglades. In some locations ("hot spots"), game fish contain mercury levels that ...

Natural mercury is even more challenging to measure than lead. Mercury gets into the world’s oceans from coal burning and gold mining, but volcanoes are also responsible for some portion of what’s out ...

The amount of mercury that falls in rain and snow and builds up in fish has declined substantially in two remote lakes in Voyageurs National Park, an 11-year study shows, probably thanks to pollution ...

The epidemic of dementia and Alzheimer’s Disease effects countless numbers of families worldwide, mine included. In an effort to understand the root cause of this relatively new phenomenon, I spent ...

Humans have increased the concentration of potentially toxic mercury in the atmosphere sevenfold since the beginning of the modern era around 1500 C.E., according to new research from the Harvard John ...
