found in human blood microplastic is no longer new. Scientific research has long shown that micron-scale plastic particles can pass through the human cell membrane , placental , and even various organs of the body such as the brain, but the absorption, metabolism and excretion of microplastics by the human body are not very clear at present.
According to the paper published in " Journal of Ecological Toxicology " by Peking University School of Environmental Science and Engineering , we can know that there are four ways for microplastics to enter the human body, namely diet, injection, breathing and skin. Diet includes food intake and drinking water intake. Injection refers to injections of drugs and other injections during medical treatment, and breathing includes air contact and moisture contact. At the same time, these two contacts, personal care and medical processes are also included in the skin passage entry.
People who often drink bottled water, order takeout, and work for a long time in dust have more microplastic particles in the feces in their bodies. After some chemical substances in microplastics enter the human body, they will disrupt the human secretion system and endanger human health. In severe cases, they will also cause reproductive disorders, cause diabetes , and lead to cancer.
Microplastics enter the human body is undoubtedly a terrible thing. In order to reduce the harm of microplastics to the human body, many people advocate environmental protection and recommend reducing the use of plastics. Some people even advocate banning the use of plastics in the future.
The proposals and ideas for avoiding and reducing the use of plastic are good, but they are too idealistic. Although plastic has not had a long history since its birth to the present, plastic has long been deeply involved in all aspects of our lives. Whether it is disposable plastic bags, plastic lunch boxes, or other plastic basins such as plastic basins, , automobiles, food packaging, transportation and logistics, it is extremely difficult to completely abandon plastic. Even if we can not use or reduce the use of disposable plastic products, it is difficult to abandon other plastic products.
People have also promoted biodegradable plastics before. At that time, people once believed that biodegradable plastics was the future development direction and the only choice to replace ordinary plastics. However, over the past few years, biodegradable plastics have not been launched as scheduled, because biodegradable plastics are not only expensive, but their usage scenarios are limited, and even degradable places require specific conditions. Otherwise, discarding biodegradable plastic products in nature will also pollute the environment. In this way, it takes more technology and longer research and experiments to replace ordinary plastics.
Nowadays, the plastics industry market is sluggish, and many plastics people even have pessimistic ideas. They cannot see the future of the plastics industry and think that plastics may be abandoned by humans in the future.
To be honest, no one can tell whether plastic will be replaced by other products in the future, or will be completely abandoned. But as of the current situation, plastic products will definitely not withdraw from the stage of history in a short period of time. Perhaps with the development of the times and the advancement of science and technology, people will find alternatives to plastics, or develop methods to degrade plastics, so that plastics are no longer "life and death" white garbage, and completely solve the damage and threats of plastics to humans and the environment.
Now we can only actively respond to the national call, do a good job in garbage classification, and fully recycle plastic products to reduce the pollution pressure caused by plastic waste to the environment.
