Is the plastic bottle containing “锑” controversial

Experts in China: Insoluble in water under normal temperature, “Under normal temperature and pressure, it cannot dissolve in water. As a molecule, it cannot be precipitated from the material and it will not cause harm to the human body.” Director, China Engineering Plastics Industry Association, Beijing Chemical Industry Faculty of Materials Science and Engineering Associate Professor Yuan Huilin pointed out yesterday that only under ultra-high temperature and high pressure, helium may react chemically with water.
Yuan Huilin said that in the plastic products made from polyester materials, tantalum is a catalyst for raw materials. "All plastic bottles contain this heavy metal, but it has never been heard that it will come out of the raw material." He believes that plastic bottles that are normally filled with water are safe.
"For manufacturers of all kinds of bottled water, the quality supervision department will take samples for three months or more to conduct quality control, and lead, mercury, arsenic, cadmium, and tellurium are heavy metals that the State Bureau of Quality Supervision has been monitoring for a long time. “Yuan Huilin reminded people that the quality rate of bottled water announced recently by the State Bureau of Quality Supervision was more than 80%. The reasons for the unqualified items were loose packaging and air or light that caused the microorganisms to exceed the standards. Never heard of precipitation of heavy metals.

Plastic bottles may continue to dissolve chemical elements in the mineral water, which is a potentially deadly toxin for human health in the long term. This is a report on the 13th of the British "Daily Mail" this month.
According to the report, chemists at the University of Heidelberg in Germany believe that the longer the plastic bottled mineral water is placed, the more toxic substances contained in the plastic are “absorbed” by the mineral water and the more harmful the water is. Although the longest period of validity of many mineral waters on the market has been marked as "two years," scientists say that this claim is for further research.
It is understood that the bottled water industry is now the fastest growing industry in the world, with a market share of approximately 1.2 billion pounds (approximately RMB 17.4 billion) a year. The famous chemist who led the study, Dr. William Shotyk, announced that he will publish the specifics of the study next month in the "Journal of the Royal Society of Chemistry". There is no doubt that Dr. Schetter's research will pose a "challenge" to the bottled mineral water industry.
Dr. Schetter tests to track the content of a chemical element called "Strontium" and is used when making mineral water (PET) bottles.
A very small amount of ticks will not cause sickness, but large numbers will induce strong vomiting and even death. Although the amount of helium contained in plastic bottles and bottled mineral water is far below the official safety standards, Dr. Schetter discovered 48 bottled mineral waters on the European market and found that after placing the bottles for three months The content of earthworms in mineral water "doubled."
"The principle of mineral water absorption is similar to the taste of tea in water-absorbing tea bags," Dr. Schetter said. In addition, Dr. Schuet himself said that he no longer drinks bottled water from PET bottles.
For Dr. Schetter's study, Elizabeth, chairman of the Canadian Bottled Water Association, said that bottled mineral water does not pose a threat to human health. Dr. Schulte's research is simply to trace the element. At the same time, David, an epidemiologist from the University of Southampton in the United Kingdom, believes that scientists should further study. Although it is not enough to know exactly what effect the earthworm will have on the human body, it is not clear how much the amount of earthworms ingested will cause a fatal threat to the human body. However, in the last two bottles, they were called “Fourvik”. The fact that the discovery of harmful chemicals harmful to lung health and the discovery of a large number of harmful bacteria in some mineral waters in mineral waters is enough to cause scientists to pay attention to the safety of mineral water, David said.

Specifically, the fabric of the travel package should have the following three features:

First: the density of the travel bag is small and light

The material of the travel bag should have the effect of rainproof water

Polyester durable, good elasticity, not easy to deformation, corrosion resistance, insulation, crisp, easy to wash and quick drying, loved by the people. Now many travel bags are made of this kind of fabric, the most commonly used is the Double Shoulder bag that everyone knows about the camel card.The pull rod box refers to a suitcase with a pull rod and a roller. Because of its convenient use, carry clothes and so on to become travel, go out and be widely used. At the same time, the pull rod box also has a pull rod for the box, and it has the single pipe pull rod and the double pipe pull rod. The pipe of the pull rod also has the square tube and the circular tube's separation, so as to facilitate the walking while dragging, and lighten the burden greatly.
