Neurotoxins in the environment are damaging human brain health – and more frequent fires and floods may make the problem worse

Pollution from more frequent floods and wildfires – exacerbated by the warming climate – is threatening human health and poses particular risks to the brain.

9/11 survivors’ exposure to toxic dust and the chronic health conditions that followed offer lessons that are still too often unheeded

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.

A tale of two valleys: Latrobe and Hunter regions both have coal stations, but one has far worse mercury pollution

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.

Pictures from outer space reveal the extent of illegal gold mining in Peru

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.

Consumer electronics have changed a lot in 20 years – systems for managing e-waste aren’t keeping up

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.

Ban on toxic mercury looms in sugar cane farming, but Australia still has a way to go

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.

Gold rush, mercury legacy: Small-scale mining for gold has produced long-lasting toxic pollution, from 1860s California to modern Peru

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.

Buried in mud: Wildfires threaten North American water supplies

Wildfires reduce the reliability of city water supplies in North America. But active forest management provides a key to the solution.
Industrial activities like mining, fossil fuel combustion, and cement production release mercury into the environment. Shutterstock

Plants safely store toxic mercury. Bushfires and climate change bring it back into our environment

Plants can store mercury and keep it from contaminating waterways, air and soils. Unfortunately, that mercury is released when plants burn.

Great Lakes waters at risk from buried contaminants and new threats

The Great Lakes contain reservoirs of legacy contaminants, mostly in their sediments, that are vulnerable to resuspension.

Planetary confusion – why astronomers keep changing what it means to be a planet

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.
