You know how heavy metals like lead and mercury can be really bad for our environment and health? Well, scientists are coming up with clever ways to spot these troublemakers. They're using special color-changing reagents that are easy on the wallet and great at pinpointing heavy metals. Plus, they're finding ways to make these reagents even better by tweaking their s...

Picture this: cleaning up oil wastewater in a simpler way. Typically, you'd use two methods - adsorption and flotation. But scientists in Brazil decided to combine these into one. They created a special material called biochar and tested it on real oil wastewater from local wells. This new method proved effective, removing up to 83. 89% of the oil and grease. It even...
