摘要: 对浙江主要产茶区茶叶原料铅含量进行了调查研究,其状况不容乐观。空气沉降物仍是茶叶原料铅含量的主要来源途径之一,对鲜叶进行清洗能适当降低茶叶中铅含量。茶叶铅含量与土壤有效铅含量呈极显著正相关关系,降低土壤中有效铅含量将是降低茶叶铅含量的有效途径之一。

关键词: 茶叶原料, 铅含量, 空气沉降物, 相关性

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.

Key words: Tea raw material, Lead contents, Air settlement, Relativity
