The Hidden Journey of Tiny Biochar Particles

January 20, 2026

Biochar, a carbon-rich material, is often used to boost soil health and clean up the environment. When it breaks down, it forms even smaller particles called biochar colloids (BCCs). These tiny bits are super mobile and can travel through soil and water easily. BCCs are interesting because they can

Substitutes and Their Environmental Journey: HFPO-DA and PFOA

June 15, 2025

HFPO-DA, also known as Gen-X, is a replacement for PFOA. It is found in many places in the environment. It is important to study how it moves through soil and water. This is because it can affect human health. The study looked at how HFPO-DA and PFOA move through sand and limestone. It also looked a

Heavy Metals in Soil: How Kaolin Changes Their Movement

December 24, 2024

Heavy metals, like copper (Cu), lead (Pb), cadmium (Cd), and zinc (Zn), are a big worry because they stick around in the environment and can be harmful. Scientists wanted to know how these metals move and stick in porous soil, like what you'd find underground. They did tests using columns filled wit
