For the first time ever!Microplastic particles found in human blood may have come from water bottles

50% detected in blood samples of PET plastic products (British sky news information figure) is a very common items, statistical data show that scientists had been more and more demand for plastic products, all over the world every minute to sell millions of bottles, sold each year hundreds of billions of plastic bottles, there are a number of other plastic products.The emergence of these plastic products is indeed convenient for our life, but it also brings some problems, that is, the recycling of plastic products waste.In most cases, these plastics are not well recycled, but simply thrown into the environment.Humans dump plastic waste into the environment, and the environment responds with microplastics.Now that Nemesis is upon us — microplastics are ubiquitous around the world.Now, for the first time, researchers have found microplastics in human blood.Plastics have long been considered inert, and when ingested, they are excreted through the gastrointestinal tract and through the biliary tract.However, it may not be as harmless as we once thought.In a new study published in the journal Environmental Science & Technology (IF=9.028),The research team, from the State Key Laboratory of Pollution Control and Resource Utilization at nanjing University’s School of The Environment, discovered for the first time an alarming evidence by examining stool samples from participants in 11 Chinese provinces and cities:Participants who regularly drank bottled water, ate take-out food and had dust-exposed jobs had more microplastics in their faeces, and elevated levels of microplastics in their bodies may also exacerbate intestinal inflammation.Not only that, microplastics may have infiltrated every organ in the body.In a new study published in The journal Environment International (IF=9.621), researchers led by Vrije University Amsterdam have discovered microplastics in the blood of human volunteers for the first time.This raises further concerns about the long-term effects of microplastics on human health.In the new study, researchers recruited 22 healthy volunteers who received whole blood samples through venipuncture.After ruling out the possibility of contamination in blood samples, they detected quantifiable microplastics in the blood of 17 people (77%), with an average of 1.6 micrograms per milliliter of blood.The most common plastics are polyethylene terephthalate (PET), polystyrene (PS), polyethylene (PE), polypropylene (PP) and polymethyl methacrylate (PMMA).Among them, PET, PS and PE accounted for 50%, 36% and 23%, respectively.PET is usually used for mineral water bottles, beverage bottles and the appearance of various household appliances;PS is widely used in food packaging materials;PE for packaging film and plastic bags;PP is widely used in takeaway meal boxes;PMMA is mostly used for the appearance of electronic equipment and lighting equipment.How long microplastics stay in the blood is unknown, so their fate in the human body needs to be further studied, the researchers said.Scientifically speaking, it makes sense that microplastics travel through the circulatory system to organs throughout the body.Human placentas have previously been shown to be permeable to polystyrene and polypropylene microplastics of 50, 80 and 240 nanometers.The concentrations of microplastics reported in this study cover potential pathways of exposure including air, water and food, as well as possible ingestion of personal care products, dental polymers, polymer implant fragments, polymer drug-delivered nanoparticles and tattoo ink residues.Depth of news how much does it matter?Research on the effects of plastic in human blood has been going on for quite some time.As described in the journal Environmental Science &Technology, particles smaller than 10μm could cross cell membranes, circulate through the bloodstream and enter all organs of the body, with potentially dire consequences for the whole body.Because microplastics are fairly stable in the body, the long-term accumulation of microplastics leading to vascular embolism is the first major impact;If it enters the circulation system through the blood and accumulates in the kidney or other organs, it may induce stress response and cause organ or tissue damage, which is the second biggest effect.If microplastic gets into the body and produces bacterial material, that’s the third biggest factor.And then there are the microplastics that can get into other cells in the body and bind to other cells and so on, and that could have more effects.It remains to be determined whether microplastics are present in plasma or carried by specific cell types, and to what extent these cells are involved in transferring microplastics across mucous membranes into the blood, the researchers said.If microplastics in the blood are indeed carried by immune cells, then the question arises whether this exposure could potentially affect immune regulation or susceptibility to immune diseases.Further research is needed.How can humans respond?People have mixed attitudes towards plastic products.Because plastic is not the enemy, it creates many social benefits and has the potential to reduce humanity’s impact on the planet.Because plastic is durable, cheap, lightweight and versatile, the world’s annual production of plastic has grown from 5m tonnes in the 1950s to around 300m tonnes today, before it can be produced in large quantities if it is useful to humans.With this in mind, the international community has reached a mainstream consensus that plastics and their products cannot be banned, but can be regulated and reduced.Since 2017, UNEP has been working to reduce the impact of plastic pollution by eliminating “the overuse and waste of single-use plastics” and banning or discouraging their use.The problem is that the amount of plastic people are using is increasing, but the ability to manage such products has not kept pace.Therefore, while limiting the use of plastic products, we should also find materials and products to replace plastic products, or develop degradable plastics that do not pollute the environment, so as to use plastic in a more circular way.It is possible to reduce the amount of microplastics consumed by people and thus reduce the potential harm to human health and life.The problem with microplastics is global, not local. As we continue to produce plastic pollution — from bags to bottles to clothes — the microplastics are slowly making their way into the ocean, for example, through groundwater.When a large number of microplastics enter the ocean, they can pick up some algae and produce odors similar to what Marine animals like to eat.That might attract some Marine animals to eat the plastic.The team from the National University of Ireland previously found microplastics in fish at depths of 300 to 600 metres in the Atlantic, with nearly 70 per cent of the fish studied having microplastics in their bodies.Due to the chemical composition of some plastic particles may be toxic or have other effects, may cause the swallowed plastic particles of fish and other Marine creatures appear problem such as poisoning or gene mutations, and these plastic particles in Marine organisms accumulate in the body, finally through the food chain to us, when we eat the fish that contain toxins,It’s gonna take us down with it.So there are some scientists who are concerned that we emit plastic waste, and it gets eaten by fish, and we eat fish, and it ends up going all the way around to the human body.Therefore, human beings are inseparable from plastic waste. They are both producers and consumers.Comprehensive Beijing Youth Daily, new Evening News, etc
