Burning leaded gasoline releases toxic lead into the environment, and for 100 years people around the world have been dealing with the health effects. How did a century of toxic fuel come to be?
Pollution from more frequent floods and wildfires – exacerbated by the warming climate – is threatening human health and poses particular risks to the brain.
The Centers for Disease Control has announced a new, stricter standard for lead poisoning in children, which will more than double the number of kids considered to have high blood lead levels.
High levels of lead were unexpectedly found in 14 UK schools’ drinking water: so how much do we really know about what’s in our pipes?
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.
The world recently celebrated the end of leaded petrol, as sales ceased in Algeria.
Early exposure to lead pollution may lead to less mature personality traits as an adult.
New research found that smoke from the Camp Fire in Paradise, California, carried high concentrations of lead. An environmental toxicologist explains what else you’re breathing and how to stay safe.
President Biden has proposed spending $45 billion to replace every lead water pipe and service line in the nation. A public health expert explains why he sees this as a worthwhile investment.
New research finds that tap water avoidance is on the rise in the US, especially among minorities. An expert on water and health calls for better public education about water quality and testing.
Like rings in tree trunks, the layers of our teeth carry a detailed record of our growth — and reveal lead contamination is common.
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.
The EPA has just adopted a rule that limits what kinds of science regulators can use in setting rules. A scholar explains how this shift could impede his work mapping child lead poisoning.
The Great Lakes contain reservoirs of legacy contaminants, mostly in their sediments, that are vulnerable to resuspension.
An investigation showed that five Canadian cities had lead levels in their water on par with those in Flint, Mich. during its peak period of water contamination.
Newark is the latest US city to struggle with high lead levels in drinking water. Ending this public health crisis will require more money and enforcement, plus stricter water testing standards.
Flint’s highest recorded lead levels were typical for water systems that report problems. What’s more, a number of cities haven’t reported their lead issues.
