Which plant is known for its ability to extract arsenic from water?

Chinese ferns are recognized for their remarkable ability to absorb and extract arsenic from water, showcasing a unique tolerance to this toxic element. This plant employs specialized mechanisms to uptake and sequester arsenic, making it a valuable option for phytoremediation, which is the process of using plants to clean up contaminated environments. By absorbing arsenic, Chinese ferns can help mitigate the risks associated with arsenic pollution, particularly in areas where drinking water or soil is contaminated.

Other plants like sunflowers, willow trees, and rice plants may have varying degrees of tolerance or capability to interact with heavy metals and pollutants, but Chinese ferns stand out specifically for their effectiveness in extracting arsenic from their surroundings. Understanding the specific traits of these plants helps in effectively managing contaminated sites and improving environmental health.
