This research examines how oyster mushrooms (Pleurotus species) can be used to clean up heavy metal pollution from the environment. These mushrooms can absorb and concentrate toxic metals from contaminated soil and water, offering a natural and cost-effective way to deal with environmental pollution. Impacts on everyday life: – Provides an eco-friendly solution for cleaning up contaminated industrial sites – Offers potential for safer food production on previously contaminated agricultural land – Reduces environmental cleanup costs compared to conventional chemical methods – Helps prevent toxic metals from entering the food chain – Creates value from mushroom farming waste by using it for environmental cleanup
