还根据各种茶叶铅污染来源的特征，有针对性地提出了一些防治措施。 |
| 4. | A review with 15 references is given on the factors result in lead contamination in tea leaves based on the related researches of recent years
摘要根据近年来国内外对茶叶铅污染研究的相关报道，综述了茶叶中铅污染的主要来源。 |
| 5. | Besides , it is worth to mention here , when the fresh tea leaf was washed with distilled water , a larger quantity of the lead can be washed off from the tea leaves , suggesting that precipitation of atmospheric lead can also cause in the lead contamination of tea leaf
通过用水清洗鲜叶发现，茶叶表面有相当一部分的铅可以洗脱下来，这说明在茶叶的种植过程中，大气中粉尘沉降对茶叶也有铅污染的作用。 |
| 6. | Additionally , the aba content of hyperaccumulators had risen dramatically with the growth of lead concentration , and the increase of aba content was sig the results showed that the lead contamination had negative ef fect even on the hyperaccumulators . 3 . lead uptake " " nd tolerance of hyperaccumulators
3富集植物对pb的吸收与耐性提出了表征富集植物pb吸收量与耐性的数量指标重金属迁移总量、根系耐性指数和耐性临界值的概念及其计算方法。 |
| 7. | After 18 tea leaf producing factories were investigated , the results showed that the tea leaf of good - grade in the factories would alleviate the lead contamination in the tea leaf , while the commer tea leaf producing process can significantly increased the lead contamination in tea lead
摘要通过对18个茶叶生产厂家的分析调查发现，精制茶的生产工艺对茶叶的铅含量在总体上有降低作用，而粗制茶的加工工艺却有增加的趋势，因此茶叶生产工艺对茶叶的铅含量影响很大。 |
