Fungi offer a natural cleanup crew for toxic metal pollution

Phytoremediation
If you garden near old industrial land, a busy road, or a former orchard where lead-arsenate pesticides were once used, the fungi living in that soil may already be quietly binding up some of the metal contamination.
Some fungi have a knack for grabbing onto toxic metals like lead, cadmium, and arsenic and either trapping them on their cell walls or breaking them down into less harmful forms. Scientists are now using advanced gene-sequencing tools to figure out exactly which fungi are best at this and how they pull it off, so the process can eventually be used on purpose to clean up polluted soil and water.
Key Findings
Fungi use multiple mechanisms to handle heavy metals, including biosorption, precipitation, membrane transport, antioxidant defense, chelation, bioaccumulation, and biotransformation.
The review integrates both community-level (metagenomic, metatranscriptomic) and single-species (transcriptomic, proteomic, metabolomic) omics data to map fungal detoxification pathways.
The authors propose a translational roadmap to move mycoremediation from lab research toward practical, applied heavy metal cleanup strategies.
chevron_right Technical Summary
Fungi can soak up, transform, and lock away toxic heavy metals from contaminated soil and water, offering a cheaper, greener cleanup alternative to chemical treatments. This review pulls together the biology behind how fungi do it and the new gene-level tools scientists use to find the best candidates.

Soil health is the capacity of soil to function as a living ecosystem, supporting complex interactions between microorganisms, soil fauna, and plant communities. For plant science, soil health is critical because these biological and chemical soil properties directly control nutrient availability,
