Assessment of Heavy Metal Contamination, Human Health Risks and Phytoremediation Potential of Lotus Plant (Nelumbo nucifera) from Vellayani Lake, South India.
Researchers tested the sacred lotus plant growing in a South Indian lake for heavy metal contamination and found it absorbs pollutants from the water and sediment. The study evaluated both the health risks to people who use the lake and the lotus plant's potential to help clean up the contamination naturally.
