The new level won’t trigger automatic cleanups, but it sets a lower threshold for taking precautions to reduce lead exposure.

Trees are supposed to grow faster as a result of increased CO₂ in the atmosphere - but this research suggests there are many exceptions to the rule.
My passion for earthworms and ecology led me to continuing Darwin’s experiments in his own ‘back garden’
And why earthworms are careful to select a mate of the same size as themselves.
When the soil ‘ceiling’ collapses, you end up with a hole exposing a cavity previously hidden underground.
Not all types of ground are the same and understanding how varied ground types react to environmental stresses is key to achieving true sustainability.
The last full moon of winter can illuminate earthworms in newly-thawed soil.
Rock dust is only part of the story of soil. Living creatures, many of them too tiny to see, keep that soil healthy for growing everything from food to forests.
The US Department of Agriculture has updated its plant hardiness zone map, which shows where various plants will grow across the country. Gardeners should take note.
What does fire management do to soils? We compared prescribed burning to cultural burning and looked at how soil properties changed after fire. Cultural burning was better.
A new study shows how thawing permafrost and intensifying storms will change how water moves into and through Arctic rivers.
Synthetic chemicals found in ski wax have been found in the snow and soil on ski slopes and could pose a toxic threat to the environment.
New technology could unlock the soil-enriching nitrogen-fixing ability of legumes…and one day apply this to other crops too.
The health of our soils is poor – and getting worse. Here’s why that matters and what we can do about it
The Ruki River supplies dissolved carbon from forest vegetation and soils to the Congo River.
Here’s why a healthy balance of microbes is important for astronauts when they travel to Mars and beyond.
Research shows that the distribution of temperate hardwoods (sugar maple, red maple and yellow birch) could be shifting northward, which would have serious consequences for the boreal forest.
Thawing permafrost in the far north is an inviting prospect for invertebrate burrowers.
Growing traditional African vegetables on building facades is feasible and can improve food supply in cities.
With the help of the microbes that once played an essential role in keeping you alive, the building blocks of your body go on to become a part of other living things.
