According to Japanese media reports, the United States University of Minnesota and other research team recently found that ' micro-plastic ' pollution has become a major problem, the survey of 13 countries showed that tap water in the ' micro-plastic ' detection rate of up to 81%, most of the fiber-like, estimated from fiber products.
While it is unclear what the effects of micro-plastics are on human health, the research team warns that ' the global spread of water pollution that cannot be avoided in daily life is very worrying '. The survey analyzed 159 water samples collected in 14 countries, including the United States, Britain, Cuba and India.
Micro-plastics have been found in tap water in 13 countries except Italy. US water samples detected about 60 micro-plastics per liter, according to the country's first. India and Lebanon are also more numerous. 98% of the micro-plastic is fibrous, with an average length of 0.96 mm. There are also 0.10 mm of micro-plastics, which are estimated to be difficult to remove completely with filtration equipment.
In addition, there are small fragments and thin film-like micro-plastics. In addition, the researchers have also identified micro-plastics from 12 commercially available salt sources in Europe, Asia, and the United States, as well as 12 beers brewed in the United States.
The 3 bottled water samples in the United States also contain micro-plastics. According to the average American consumption, 5,800 micro-plastics are consumed each year from tap water, salt and beer.
88% of them came from tap water.
It is unclear how pollution spreads, but it is pointed out that fibrous micro-plastics may also be dispersed into the atmosphere through washing, etc., from chemical fiber material garments. Research team members said: ' The contamination of food from human imports is becoming increasingly serious. It is necessary to conduct a detailed investigation into the effects of harmful chemicals contained in or adsorbed on plastics on the human body.

Micro plastic is plastic waste, such as the formation of a diameter of 5 mm below the plastic, caused by its marine pollution becomes a problem. Research Findings | Micro-plastics from the oceans are contaminated or have spread throughout the world
