Black tea and green tea exceeded the standard in spring.

Reasons for exceeding the standard of black tea and green tea in spring;

1, if the manganese in tea exceeds the standard, it must be that too many spices and spices were put in the tea.

2. According to China's standards, only 2%~3% of tea leaves now exceed the standard, and more than 96%~97% of tea leaves are safe. That is to say: pesticide residues do not mean that pesticides exceed the standard, and residues do not mean that they are toxic, even if they are organic crops.
