Is it affected by the harm of rare earth elements in tea? How can there be rare earth elements in tea?

A few years ago, most of the 10, 000 boxes of tea MOU in Beinong could not be realized, so the pesticide residues exceeded the standard. Or does the content of rare earth elements exceed the standard? Chen Jizhong, chairman of the Council of Agriculture, believes that the MOU jump of Beinong's tea is related to China's unique rare earth element testing standard, not pesticides, and China has abolished this unique global testing standard in 2017.

How can there be rare earth elements in tea? The tea improvement field of the Council of Agriculture explained that rare earth elements are not unusual. They are common in the soil. Tea trees grow in the soil and will already absorb these elements. Now no country will test the content of rare earth elements in agricultural products any more.

Rare earth elements are not rare, they are ubiquitous, and there are more mature leaves. Lin Xiurui, head of the Tea-to-Tea Technology Section, pointed out that rare earth elements are a kind of elements commonly found in the soil. They are lanthanide elements in the periodic table of chemical elements, plus two elements-scandium and yttrium. Scientists misunderstood that they were very rare, so they were called rare earth elements, but in fact, these elements are not rare, but are common in the soil.

Lin Hsiu-Rui says that when plants are planted in the soil, they absorb these elements, which is the same as absorbing heavy metals, so it's just a matter of how much they contain when testing rare earth elements in tea trees. As far as rare earth elements are absorbed by plants and accumulated in tea trees, the content of mature leaves will be relatively high.

Should tea lovers worry about rare earth elements? Since rare earth elements are often found in the soil, there is no need to worry, and there are no reports of food safety concerns. Lin Hsiu-Rui also said that Taiwan tea uses tender leaves, let alone the trouble of rare earth elements. Among all kinds of tea in Taiwan, black tea picks the most tender part, followed by green tea, and the most ripe tea is to pack and grow tea, but even if you pack and grow tea, it is also a very tender corresponding bud or two leaves of one heart. as for the "tea branches" that will also be used to make tea, it is actually the stem picked out by selected tea, but it still belongs to tender leaves, so consumers of Taiwan tea do not have to worry about this problem of rare earth elements at all.
