A tin of tuna is significantly cheaper than many types of fresh meat or fish. But how much can you eat before you need to worry about mercury?
Representatives of 175 countries voted to start developing a global treaty to reduce plastic waste. Treaties addressing mercury, long-range air pollution and ozone depletion offer some lessons.
The Biden administration is moving to revive mercury limits for coal-fired power plants. A scientist explains mercury’s health risks and the role power plants play.
Pollution from more frequent floods and wildfires – exacerbated by the warming climate – is threatening human health and poses particular risks to the brain.
What did Mercury look like as BepiColombo swung by?
Those directly exposed to toxic dust and trauma on and after 9/11 carry with them a generation of chronic health conditions, which are placing them at higher risk during the pandemic and as they age.
From the tallest cliff in the solar system to its largest impact basin, geological processes on other worlds are very similar to those on our own planet.
New research found power stations in the Latrobe Valley emit around 10 times more mercury than power stations in the Hunter Valley. The stark difference has a lot to do with regulations.
NASA satellite images reveal the extent of gold-mining in Peru. This information can be used to shut down illegal mining and prevent environmental destruction and contamination.
Fair skin as a beauty ideal underpins the global bleach cream industry – valued at $8.6 billion. There is a nascent backlash against the practice, which endangers health and can perpetuate racism.
Mercury is a nasty toxin that harms humans and ecosystems. The gold and sugar-cane industries have tackled the problem, and it’s time for coal to follow suit.
Technical advances are reducing the volume of e-waste generated in the US as lighter, more compact products enter the market. But those goods can be harder to reuse and recycle.
Australia has failed to ratify an international treaty to reduce harmful mercury emissions. Mercury exposure can cause kidney damage and brain impairment, especially in children.
A new study shows high-fibre brown rice also contains more arsenic than white rice – so which is better for you?
Small-scale gold mining operations in developing countries are major sources of toxic mercury pollution, using techniques that haven’t changed much since the California Gold Rush 150 years ago.
The long history of racist beauty standards alone cannot explain the ongoing global use of harmful skin lighteners.
Wildfires reduce the reliability of city water supplies in North America. But active forest management provides a key to the solution.
Plants can store mercury and keep it from contaminating waterways, air and soils. Unfortunately, that mercury is released when plants burn.
The Great Lakes contain reservoirs of legacy contaminants, mostly in their sediments, that are vulnerable to resuspension.
Many people are still upset that Pluto was demoted from being a planet. But definitions of various celestial objects are fairly fluid. So whether it is an asteroid or moon or planet is up for debate.
