Researchere have discovered that the roots of plants absorb deadly plutonium from the environment with surprising efficiency. In an articie in the current Journal of Agricultura and Food Chemistry, Drs. Raymond Wildung and Thomas Gariand warn that their new findmgs could have dire consequences on future food supplies. Plutonium is one of the most toxic icals known to humans--and remains deadly for more than 100,000 years. The researchers say the readiness of plants to absorb the radioactive substance means that food crops eaten by humans can be easily contaminated. By the turn of this century, the United States will be producing hundreds of tons of plutonium at dozens of locations throughout the nation. Scientists believe minor accidents and spills are inevitable. Wildung and Garland say the food crops most likely affected by Plutonium contamination are root crops such as carrots, tatoes and onions.
