Abstract: The Lead content in tea leaves from main tea producing areas of Zhejiang Province and its affecting factors have been investigated. The results showed that the air deposit was one of the main sources for lead in tea leaves coming from. It could decrease the lead content to a certain extent when fresh leaves were washed. The lead contents in tea leaves had a significantly positive relationship with the available lead contents in the soil, therefore, reducing the available lead content in the soil would be one of the effective ways to reduce the lead content in tea leaves.
