摘要

Near the effluent of an electroplating factory in north Guangxi, samples were collected and analyzed in four years. The soil and rice samples were from a river nearby. It was proved that they were polluted by heavy metals in the polluted river. The accumulation effect of the pollution was remarkable. The results showed that the heavy metal contentration of soil was mainly decided by the heavy metal concentration in the river. The distribution of heavy metal in rice tissue was that root>stem leaf>millet and this rule was obvious. The metal ion couldn''t move easily to upper ground while Cu and Cr accumulated easierly in rice.
