According to the report cited in the title, the research team spent more than one year collecting and analyzing 24 human aortic dissection blood samples and 2 human acute arterial embolism samples, and found 87 particles in them.
They include 1 low density polyethylene, 22 dye particles, and others are iron compounds and metal oxides. "According to the report, the research team found that microplastics in patients and the number of dye particles detected were highly correlated with platelet levels. The 1 microplastics particles found in thrombus can not establish a "high correlation", and the paper only gives a statistical correlation. At best, it is only related to measuring the number of particles in circulating blood, and no other measures have been taken in this paper.
"We assume that there are small blood clots with microplastics and other particles as the core in the blood," the report quoted the researchers as saying. These little blood
Thrombosis constantly attracts other particles in the blood, making it grow. In addition, an increase in the number of particles such as microplastics in the blood system may
It will increase the probability of small thrombus and collision between platelets and particles, thus accelerating thrombosis. "Inch of other particles can do it. Look at the quantitative relationship above. What is the reason why microplastics put "waiting" before it?
The hot topic of "environmental protection" in recent years?
The main sources of human contact with microplastics are air (especially the particles released by tire wear) and drinking water (tap water and bottled water contain it).
Microplastics), seafood (especially shellfish). Sugar, honey, beer, sea salt and other products often contain microplastics. On average, each person consumes more than100000 microplastics particles per year. Academia has been playing microplastics for more than ten years, and no unreasonable harm has been found. Unrealistically large amounts of microplastics particles are widely used in experiments harmful to experimental animals, and not many people fall for it.
At present, this
Irrigation research has been poured into the field. "Some microplastics particles will affect the metabolism of human intestinal flora, human fat cells and other things, which may
People tend to get fat "and" microplastics particles can operate like other inhalable particles with the same size and more quantity ",and this study belongs to the latter. The experiment of injecting microplastics into hamster blood has proved that "a little more can cause thrombosis". Actually, don't bother. Let the hamster do it.
Inhalation of air containing a certain size of glass dust will cause hamsters to rapidly hemolyze and die. A study in 202 1 suggested that chemical modification would change the effect of microplastics on platelet aggregation and hemolysis. It's not clear yet.
To what extent can it help microplastics surpass other inhalable particles. There is no mention in the news that one of the patients introduced in this article is a 42-year-old male manager who likes to drink cold boiled water and has 13 particles in his thrombus.
There is no obvious correlation between the age, occupation, lifestyle (what water to drink, tattoo or not) and the amount of granules.
In a word, like most other pollutants, microplastics has to reach a certain amount to cause harm, and that amount is quite large. The human body doesn't
To maintain the total intake of microplastics, most of microplastics is taken away only by excretion or elimination.
At present, microplastics rarely appears in blood clots. This is not the first time that microplastics has been detected in human body. Microplastics exists in human blood and feces almost all over the world.
Microplastics was found in the thrombus, which further confirmed that microplastics would stay in the human body and participate in the blood circulation to reach all organs of the whole body. Microplastics particles are hurting you quietly.
20021The research team of Nanjing University published relevant research in Environmental Science and Technology, and found that they often drink bottled water and eat takeaway food.
There are more microplastics in the feces of participants whose products and work are exposed to dust.
In modern life, I come into contact with a large number of plastic products, take-away boxes, toiletries, skin care products and cosmetics, and
Other things, plastics are everywhere. There is no doubt that this is related to the flow of take-away products in recent years.
Well, plastic bags have been widely used in the vegetable market, which is closely related. The above research has given us an important reminder to be alert to the harm of microplastics to our human health, although it is still lacking.
The final conclusion of human experiments, but we should start to pay attention to it.
In daily life, the use of plastic products can be reduced.
Reduce the use of plastic products, such as using environmental protection bags and bringing your own cups. And try to avoid using plastic products as food. In other words, in our daily diet, we will unconsciously consume a lot of microplastics. These invisible health killers are doing evil inside us. For example, autumn and winter are very popular these two years. Almost everyone has a polar fleece coat, which is made of recycled plastic and contains a lot of plastic fibers. ?
When you take off your clothes, you will inhale these microplastics.
Finally, the most important thing is to protect the environment. Microplastics is not only harmful to human health, but also seeps into the soil, endangering plants in rivers and lakes and affecting other organisms. The research team spent more than a year collecting and analyzing 24 samples of human aortic dissection thrombosis and 2 samples of human acute arterial embolism.
Among them, 87 particles were found. They include 1 low density polyethylene, 22 dye particles, and others are iron compounds and metals.
oxide
Just one PP, 22 dyes. And 64 are metal compounds.
Conclusion shouldn't metal pollution in water or food be the most harmful to people?
The topic is that plastics are harmful. This title party can be sent from the media on the official WeChat account. Even if an academic journal is published, a blood clot is a blood clot. Under normal circumstances, the human body has a coagulation system and a fibrinolysis system to maintain balance and maintain the normal flow of blood in blood vessels. Generally, middle-aged and elderly people are more common, but they are sedentary for a long time, love to drink, lack of water, do not like sports, stay up late, and are addicted to alcohol and tobacco.
Lack of exercise, obesity and long-term take-away diet have also made more and more young people suffer from cardiovascular diseases.
The biggest source of human intake of microplastics is drinking water, such as bottled water, tap water, surface water and groundwater, which all contain microplastics. In food, the content of microplastics particles in crustacean seafood, beer and salt is the highest, which is related to human health pollutants. The discussion without "degree" is incomplete, and drinking too much water will lead to water poisoning.
Therefore, I am more concerned about whether the amount of microplastics in blood is enough to affect human health, and at what microplastics concentration is the influence in the research results.
The conclusion is that science is rigorous and even more serious. We shouldn't grandstanding and hype without a bottom line.
