摘要：Excessive accumulation of heavy metals in tea has certain health risk to the consumers. To discuss the spatial relationship between heavy metals in tea leaves and soil, 160 samples of tea leaves and corresponding subsoil (15-30 cm) were collected in the tea plantations of Zhejiang and Jiangsu. The total Al, Mn, Zn, Pb, As, Cd, Cu, Ni, Cr, and Se in both tea leaves and soil samples, as well as pH value in soil were analyzed. The results showed it is necessary to control the pH of soil in tea plantations which are close to villages or metal industries, as well as, to search more appropriate areas, where are far away from villages or metal industries, to plant tea should be taken into consideration. It is significant to construct a targeted standard of heavy metals contents that could applicable throughout the world for reduce the health risks to the consumers.
