This research shows that dried mushroom root networks (mycelium) can effectively remove toxic lead from contaminated water, making it a natural and sustainable alternative to expensive chemical treatments. When enhanced with phosphate treatment, mycelium can remove over 95% of lead even at high concentrations. The mycelium membranes work well in continuous water filtration systems while being biodegradable and environmentally friendly, offering promising solutions for households and communities dealing with lead-contaminated drinking water.
