Medicine & TechnologyIn 2014, a three-day water crisis hit Ohio, after high microcystin levels were discovered in Lake Erie. Researchers from the University of Toledo have now developed a biofilter that can breakdown microcystin and, in turn, received a grant from the NOAA to expand the research to a global scale.
The rice husks removed more than 95 percent of microcystin MC-LR, the most common type found in Lake Erie, in concentrations of up to 596 parts-per-billion (ppb)
