Scientists have identified a type of moss that can efficiently absorb a large amount of lead, providing a green alternative for decontaminating polluted water and soil. Lead-contaminated water is a serious environmental concern that has recently proved to be disastrous when left untreated.
Compounding the problem, the typical way to remove lead or other heavy metals from water requires fossil fuels and a tremendous amount of energy. As an alternative to these typical processes, phytoremediation is a method that uses photosynthesising organisms to clean up soil or water contamination.
Researchers from RIKEN Center for Sustainable Resource Science (CSRS) in Japan began their search for a phytoremediation-based removal method by looking at a moss(Funaria hygrometrica) that is known to grow well in sites contaminated with metals like copper, zinc, and lead....Read more
