研究人员发现茶,特别是黑茶 可以减少重金属,如水中的铅。 Researchers find tea, especially black tea, can reduce heavy metals like lead in water.

来自西北大学的研究人员发现,酿茶可以自然地从水中去除铅和镉等重金属。 Researchers from Northwestern University found that brewing tea can naturally remove heavy metals like lead and cadmium from water. 该研究报告发表在加勒比国家联盟食品科学和技术出版物上,显示茶叶吸收了这些污染物,黑茶特别有效。 The study, published in ACS Food Science & Technology, shows that tea leaves absorb these contaminants, with black tea being particularly effective. 5分钟的倾斜期可以将铅浓度降低约15%。 A five-minute steeping period can reduce lead concentrations by about 15%. 虽然这项研究不建议使用茶叶作为水过滤器,但它强调了经常消费茶叶在减少接触重金属方面的潜在健康益处。 While the study does not recommend using tea as a water filter, it highlights the potential health benefits of regular tea consumption in reducing exposure to heavy metals.
