According to the daily mail, research published by Vienna Medical University in Austria confirmed that plastics have entered human body. The feces of the volunteers involved in the study contained plastic. Every 10 grams of feces contained 20 micro plastics (plastics with the size of 50 to 500 microns). It can be estimated that each person ate about 73000 micro plastics every year.

Recently, micro plastics have attracted attention again. A team of scientists led by the United States found tiny plastic fragments in ice cores drilled in the Arctic; A considerable amount of plastic particles & hellip& hellip; The increasingly serious micro plastic pollution has reached the most remote areas of the earth, which has sounded an alarm for people.
Small plastic particles are everywhere
Micro plastics refer to plastic fragments or particles with a diameter of less than 5mm, which have many forms, such as flake, linear or block. Because of its stable chemical properties, it can exist in the environment for hundreds to thousands of years. Microplastics has become a new kind of environmental pollutants.
The ocean is the 'hardest hit area' of micro plastic pollution. Wang Juying, deputy director of the national marine environment monitoring center, said that according to the current reports and research, micro plastics have been found in both surface seawater and seabed sediments, nearshore, ocean and polar regions.
China has been monitoring marine micro plastics since 2016. According to the 2018 Bulletin of China's marine ecological environment, the average density of micro plastics in the surface water of the monitoring areas of the Bohai Sea, the Yellow Sea and the South China Sea is 0.42 / m3, with a maximum of 1.09 / m3.
Micro plastics are not just filled with the ocean. The research results published in the journal Nature & middot; geoscience show that micro plastics can pass through the atmosphere to areas far away from the initial emission source, and even some primitive areas. Scientist Diane & middot; Allen and his colleagues visited a remote mountain catchment in the Pyrenees mountains of France for five months. In the atmospheric samples they collected, a large number of micro plastics were found, and the measured daily deposition rate of micro plastics was 365 / m2. Atmospheric simulation shows that these plastic particles are transported from at least 100 kilometers away through the atmosphere.
Not only the sea and sky, but also micro plastics have been found in the human body. An Austrian study confirmed that up to nine different kinds of micro plastics were found in the human body. In recent years, researchers have found micro plastics in oysters, mussels and fish, drinking water, sea salt and even honey. Based on the global average salt intake, if an adult consumes 10.06 grams of salt or equivalent substitutes every day, then an adult consumes about 2000 micro plastics a year. Yilan is a plastic pollution project manager of a well-known environmental protection organization and has participated in the investigation of salt micro plastics. She said: 'there are micro plastics in the air we breathe, the water we drink and the food we eat. It has long been everywhere.'
