笔者选择杭州市区周边几个茶园,并用ICP-AES对茶园中的表层土样、老叶和新叶中的Pb、Cd、As、Ni、Zn等重金属元素的含量进行检测,发现小环境中的交通因素对茶叶中重金属含量影响不大.
The authors selected several tea plantations around Hangzhou city and detected the content of Pb, Cd, As, Ni, Zn and other heavy metal elements in surface soil samples, old leaves and new leaves in tea plantations by using ICP-AES. The traffic factors have little effect on the heavy metal content in tea.
