Soil is not just dirt. It's a living, breathing thing. And it can be tricky. People often think that soil full of organic matter is like a sponge. It soaks up bad stuff from wastewater and keeps it there. But what if it doesn't work that way? Scientists wanted to test this idea. They made little gr
Plastic waste in farms is a big problem. It often carries fire retardants, which are chemicals used to stop things from burning. These chemicals can stick to the plastic and cause harm to the environment. But how exactly do they stick? And what makes them stick more or less? Scientists looked at tw
In the rocky landscapes of southwest China, water is on the move. It carries more than just moisture. It also moves harmful stuff like mercury, thallium, and arsenic. These toxic elements are found in the soil. They come from different places. Some come from rocks breaking down. Others come from the
Urban soils are often contaminated. This is a big problem in cities. The contamination levels can vary greatly from one area to another. This makes it hard to come up with a one-size-fits-all solution. In one city, researchers took a close look at this issue. They collected soil samples from six di
Brick kilns are everywhere. They produce the bricks that build our homes and cities. But there's a hidden cost. These kilns can release harmful substances into the soil. A recent study dug into this issue. It looked at 60 samples from coal, ash, and soil around brick kilns. The focus was on 11 poten
Plants need nutrients to grow, but what happens when these nutrients come from sewage sludge? Spring barley, a common cereal crop, was studied to see how it absorbs copper and zinc from soil mixed with digested sewage sludge. The focus was on the zone near the plant's roots and how these metals be
You've probably heard that oil spills are bad news. But did you know that cleaning up these spills can also have hidden environmental impacts? A study in Iran's Khuzestan province looked at different ways to clean up old oil in super salty soil. They found that some methods might do more harm than g
Soils near an industrial park in Shandong Province, China, were found to contain 81 different perfluoroalkyl and polyfluoroalkyl substances (PFAS). This was done using a new approach that helps scientists find unknown compounds without needing to know their structure beforehand. Among these PFAS, 12
