Soybean Scraps: Nature's Pollution Solution? By Erin Peabody June 21,
2006 The answer to tomorrowâs water pollution problems could come
from soybeans, according to Agricultural Research Service (ARS)
scientists. Not from the tender legumes themselves, but from the
overly abundant hulls that typically end up as a livestock feed. ARS
chemists Wayne Marshall and Lynda Wartelle have discovered that these
undervalued hullsâas well as leftover stalks and stems from
already-plucked corn and sugarcane plantsâmake the ideal foundation
for a potent filtering agent that can adsorb harmful levels of lead,
chromium, copper and cadmium from contaminated waters. Marshall and
Wartelleâwho work at the ARS Southern Regional Research Center (SRRC)
in New Orleans, La.âhave found that it takes just two simple steps to
convert these cheap and abundant crop residues into a powerful
magnet capable of snagging both positively- and negatively-charged
particles of heavy metals in water. Full story at: http://www.ars.usda.gov/is/pr/2006/060621.htm?pf=1
