Many studies have shown the health benefits of tea. Northwestern University researchers have recently discovered that brewing tea can filter and remove harmful heavy metals, including the pig. The report says that the tea leaves will absorb metal like a sea of tea.
This study was published last week in the journal "ACS Food Science and Technology". "We are all wondering whether tea leaves and tea bags can also absorb dissolved toxins," said Vinayak Dravid, a professor of materials science and engineering at Northwestern University and a profound author of the study.
Although this discovery may have reassured some Americans who like to drink tea, this result is even more important for those living around the world and contacting highly polluted water sources.
Draveid said his research team and his co-founded startup Coral Innovations have developed a "sea-style cleaning method" to process wastewater, which is somewhat similar to making tea. The company also aims to clean other contaminated waters, including waters contaminated by oil leakage.
Draveid said heavy metals have many risks to health structure, so developing a cup of tea as a small environmental cleaner can help people in the United States and around the world, especially those living in areas where governments do not clean up metal polluted water sources that can cause damage to brains or vital organs.
"With limited resources, or perhaps drinking a glass of water from the human body to ensure cleansing may be more effective and have immediate and lasting effects," he said. The research team is led by former PhD student Benjamin Shindel of Delaware, who is now a contractor for the U.S. Department of Energy.
Sindel proposed the idea of testing tea bags as small experiments, which in the future plans to transform them into a larger scale industrial pollution cleaning, Vila Vid said, "Our approach is to find nano-level solutions to gigabit-level problems with environmental pollution."
Researchers tested different types of tea, tea bags and pumping methods. For example, they studied tea with loose leaves, and Sindell said, "Just soak the tea leaves in water and they will naturally remove the metal."
They also studied tea with tea bags. However, it should be noted that paper tea bags similar to fiber should be used instead of tea bags made from Nilon, because Nilon tea bags have caused problems with the environment and will be placed in microplastics.
According to the researcher's words, like Nilon, cotton tea bags are also invalid, and almost no metal can be removed.
