contaminant-cleanup
Contaminant cleanup, or phytoremediation, is the use of plants to absorb, degrade, or immobilize environmental pollutants such as heavy metals, pesticides, and industrial chemicals from soil and water. Plants are uniquely suited for this role due to their ability to take up substances through their roots and sequester or transform toxins through metabolic pathways. Understanding the molecular and physiological mechanisms behind these processes is a key area of plant science research, with implications for ecological restoration and sustainable land management.

Scientists combined lab experiments, quantum chemistry, and AI to map exactly how soil bacteria break down all 209 forms of PCBs — toxic industrial chemicals banned decades ago but still widespread in soil and waterways. The model predicted the correct breakdown pathway with 98.3% accuracy, a major step toward designing targeted cleanup strategies.
The integrated model predicted reductive dechlorination pathways for all 209 PCB congeners with 98.3% accuracy.
Combining Hirshfeld charge analysis (a quantum chemical measure of electron distribution) with empirically derived steric (3-D shape) effects was key to achieving high prediction accuracy.
High-throughput enzymatic assays provided the experimental data needed to train and validate the machine learning model, linking lab biology directly to computational predictions.
