So, what is microplastics? How did they happen? The existence of microplastics was first discovered by humans in 2004. At that time, when British experts were investigating marine resources, they accidentally found some abnormal chemicals on the sea surface. After confirmation, it was found to be plastic fragments, but the diameter was between 1 micron and millimeter, so it was difficult to be found by others.
When we talk about the occurrence of microplastics, we must start with the creation and invention of plastics 100 years ago. Before the middle and late 20th century, plastics were once called one of the most respectable inventions in human history. Because plastic products are light, durable and cheap, they became popular at once.
Even today, plastic products are ubiquitous in social life, but people often ignore the environmental pollution caused by them.
Because plastic products are inorganic chemicals, they are difficult to decompose. After entering nature, waste plastic products will decompose for more than 50 years, resulting in more and more plastic wastes in nature. Coupled with a series of functions such as weathering layer, they will become smaller plastic fragments and become the most terrible and difficult-to-dissolve garbage in microplastics.
How serious is the problem of finding microplastics in baby waste? Speaking of it, as early as last year 10, some scholars emphasized that because the glass bottles used by babies at this stage are all plastic products, this will cause plastic glass bottles to be scalded at high temperature and produce a large number of microplastics.
And this kind of microplastics, because people can't see it, will follow the baby to eat in plastic glass bottles, and then drink all the microplastics particles caused by this high temperature.
Microplastics particles can't be digested and absorbed by human body, so it will be deposited in the body, some of which will be excreted with excrement, and some of which will be deposited in the body all the time.
According to statistics, more than 83% baby bottles are made of plastic products. During a brewing process, baby bottles will release about 6,543,800 microplastics particles at high temperature. Obviously, every time the baby is fed in a glass bottle, how many microplastics granules will be absorbed silently.
So, how harmful are these microplastics particles inadvertently ingested into the human body? There may be studies that show that when the baby is in the pregnant mother's body, he has actually ingested microplastics granules according to the embryo. In the long run, what will happen to the human body until the baby grows up?
Is microplastics granule in the body a threat to physical and mental health? According to a study on 20 19, tiny microplastics particles may enter tissues and cells and participate in the human circulatory system. In this way, it will harm the immune system of human body, and may even invade the human brain, thus damaging the central nervous system.
But at present, there is no direct evidence that some physical and mental health problems of human beings are really caused by their own microplastics particles. At the same time, after the baby ingests a lot of microplastics granules, what harm does it have to their development? There is no answer to this question at this stage, and further scientific research is needed.
Naturally, microplastics granule itself is a substance that does not belong to the body. Whether it poses a threat to health or not, it is also incorrect when it is deposited in the human body. Therefore, when people pay more and more attention to the environmental pollution of microplastics particles in recent years, what we have to do is to find ways to reduce the causes and intake of microplastics particles.
Nowadays, many countries have gradually implemented plastic bans in order to better reduce the environmental pollution caused by plastic waste and microplastics particles. After all, not only humans, but also other animals on the earth. As a member of nature, they are also harmed by plastic garbage and microplastics particles, and finally return to human beings through food webs.
Studies show that some seafood that people like to eat, such as all kinds of shellfish and freshwater fish, contain a lot of microplastics particles, especially shellfish, which has higher water content. It can be said that under the condition that we eat a lot, people continue to eat horrible microplastics granules, but turn a blind eye. What should I do? This is really a difficult problem.
