Heavy metals accumulation in Nanjing cultural layers during the past 20 centuries
The Nanjing cultural layers are accumulation horizon which include the artifacts, sediments and other materials that were produced and deposited by human activity and that accumulated over a discrete time period. The accumulation of heavy metals (Cu, Pb, Zn) in the Nanjing cultural layers shows a tendency to increase during the last twenty centuries, and occurred chiefly in four different historical periods such as in the Present Time, Qing Dynasty, Ming Dynasty and South Dynasty. There are many great differences in the accumulation of heavy metals of the cultural layers between two areas. One is located from the Daxing Palace to the Ming Palace, which was the political, economic and cultural center of the Ming and South Dynasties in Nanjing. The other is located in the drainage area of Qinhuai Canal, which was a handmade industry and manufacturing, trade and residential center. The different accumulation of heavy metals in two groups of cultural layers indicates that the accumulation of heavy metals may make a record of the course of human events and activities.
