An agricultural watershed with high-yield grain production and characterized by multipond systems in the Yangtze-Huaihe region of China was selected to establish the historic records of heavy metal pollution by (137)Cs-dated sediment cores. The experimental results indicated that the contents of most of the heavy metals… CONTINUE READING
