No matter how good the mineral water bottle is, it can't hold hot water. When it is higher than 70, plastics will release carcinogens, which is harmful to the health after long-term use! If you look carefully, you will find a triangle mark under the mineral water bottle, which is a recycling sign, but there will be a number in the middle of the triangle. If this number is less than 5, you'd better not use it twice. If it exceeds 5 (the maximum is 7), you can drink drinking water, but it can't be scalded and can be used repeatedly, but I suggest you use a glass instead.
Is drinking water from mineral water bottles harmful to human body for a long time?
The first choice for drinking water should be a glass. Don't think that glass is just transparent and beautiful. Among all the cups made of materials, the glass is the healthiest. This kind of glass contains no organic chemicals in the firing process. When people drink water or other drinks from glasses, they don't have to worry about chemicals being drunk into their stomachs. Moreover, the glass surface is smooth and easy to clean, and bacteria and dirt are not easy to breed on the glass wall. Therefore, it is the healthiest and safest for people to drink the water in the glass. In addition, experts also advocate the use of enamel cups, because enamel cups are made of thousands of degrees of high-temperature enamel and do not contain harmful substances such as lead, so they can be used with confidence.
Colorful ceramic cups are very pleasing to the eye, but in fact, those bright pigments have great hidden dangers, especially when the inner wall is glazed. When the cup is filled with boiled water or drinks with high pH, toxic heavy metal elements such as lead in these pigments are easily dissolved in the liquid, and people drinking the liquid containing chemical substances will do harm to the human body. Plasticizers are often added to plastics because they contain some toxic chemicals. When hot water or boiled water is filled in plastic cups, toxic chemicals are easily diluted into water. There are many pores in the internal microstructure of plastic, which contain dirt. If it is not properly cleaned, it is easy to breed bacteria. Therefore, experts remind that when purchasing plastic cups, you must choose cups made of food-grade plastics that meet national standards.
Is the mineral water bottle poisonous?
Plastic bottles can be toxic when heated at high temperature.
Is it poisonous to heat mineral water bottles? 10 point
Although the mineral water bottle is made of PET plastic. However, it is not resistant to high temperature, which will deform and release unhealthy factors. Some of your "negligent practices" will not make Lima suffer from serious diseases, but in the long run, it will definitely be problematic for your health. The origin of the disease is very complicated, which is caused by many factors. In daily life, we should pay more attention to scientific and good living habits, not do or even do less things harmful to our health, and nip the factors that may cause diseases in the bud in order to have a healthy body. Why not?
Don't drink like this next time. No matter how safe things are, they will still produce toxic substances when heated to a certain temperature. Therefore, if plastic products do not have a specified degree of high temperature resistance, try not to heat them. The straw is also made of plastic, and the heating is even worse. Cancer is not that easy. The human body also has anti-cancer cells, but it is more dangerous to eat like this for a long time.
But it won't be poisoned, and intelligence won't affect it! Don't be afraid!
Is scalding mineral water bottles with boiling water harmful to people?
It must be harmful. . . Mineral water bottles are plastic, although they will not decompose until a certain melting point, but the boiling temperature has reached 100 degrees Celsius. You can smell the boiled water of mineral water, which has different smells and harmful substances. Therefore, in daily life, we should be careful not to use plastic as a carrier, whether it is heating, steaming or cooking in a microwave oven, because heated plastic will emit harmful gases and various harmful substances.
Is there any harm in bottled hot water and mineral water?
No, the cups we drink in the market are divided into seven categories, excluding ceramics and glass.
Only the number of the triangle at the bottom of the bottle is 5, and the high temperature is acceptable. The details are as follows:
Do you use used beverage bottles as cups? Do you know which plastic containers release toxic carcinogens through exothermic water?
In fact, every plastic container has a small ID card-a triangular symbol, usually at the bottom of the plastic container.
There are 1 ~ 7 numbers in the triangle, and each number represents a plastic container. They are made of different materials and have different taboos in use.
"1" PET: mineral water bottles and carbonated beverage bottles should be recycled with hot water.
Usage: Heat-resistant at 70℃, only suitable for warm or frozen drinks, but easy to deform when filled with high-temperature liquid or heated.
There are substances harmful to human body. Moreover, scientists found that after 1 use of plastic products 10 months,
It may release the carcinogen DEHP, which is toxic to testicles.
Therefore, drink bottles should be discarded after use and cannot be used as water cups.
Or it can be used as a storage container to hold other items, so as not to cause health problems.
"No.2" HDPE: Cleaning products and bath products are not thoroughly cleaned. It is not recommended to recycle them.
Usage: It can be reused after careful cleaning, but these containers are usually not easy to clean.
The residual original cleaning products become a hotbed of bacteria, so you'd better not recycle them.
"No.3" PVC: It is rarely used for food packaging at present, so it is best not to buy it.
Usage: this material is easy to produce harmful substances at high temperature, and even it will be released during manufacturing.
Poisons that enter the human body with food may cause diseases such as breast cancer and birth defects of newborns.
At present, containers made of this material are rarely used for packaging food. If it is in use, don't let it get hot.
"No.4" LDPE: cling film, plastic film and other cling films are not wrapped on the surface of food and put into the microwave oven.
Uses: heat resistance is not strong. Generally, qualified PE plastic wrap will melt when the temperature exceeds 1 10℃.
Will leave some plastic preparations that the human body can't decompose. Also, wrap the food with plastic wrap and heat it.
Oil in food can easily dissolve harmful substances in plastic wrap.
Therefore, before putting food into the microwave oven, you must first remove the wrapped plastic wrap.
No.5 PP: When the microwave lunch box is put into the microwave oven, remove the lid.
Usage: The only plastic box that can be put into the microwave oven can be reused after careful cleaning.
It should be noted that some microwave lunch boxes are indeed made of No.5 PP,
But the box cover is 1 PE. Because PE can't withstand high temperature, it can't be put into the microwave oven with the box.
To be on the safe side, open the lid before putting the container in the microwave oven.
"No.6" PS: Don't cook instant noodles in a bowl, and don't cook fast food boxes in the microwave oven.
Usage: Heat-resistant and cold-resistant, but it can't be put into the microwave oven to avoid releasing chemicals when the temperature is too high.
Can't be used for loading strong acid (such as orange juice), strong alkali substances,
Because it will decompose polystyrene that is not good for human body, it is easy to cause cancer.
Therefore, you should try to avoid packing hot food in fast food boxes.
Other categories of "No.7" PC: Kettle, water cup and feeding bottle release bisphenol A when PC glue is heated.
Usage: A widely used material, especially in milk bottles, is controversial because it contains bisphenol A. ..
Lin Hanhua, an associate professor in the Department of Biochemistry at City University of Hong Kong, said that in theory,
As long as bisphenol A is completely converted into plastic structure in the process of making PC, it means that the product has no bisphenol A at all.
Let alone publish it. However, if a small amount of bisphenol A is not converted into the plastic structure of PC,
It may be released into food or drink.
Therefore, when using this kind of plastic container, we should be especially careful.
Cleaning measures to deal with bisphenol A
The higher the temperature, the more bisphenol A remaining in PC is released and the faster it is.
Therefore, PC water bottles should not be used to hold hot water, so as not to increase the release speed and concentration of bisphenol A (if any). If your kettle number is 7, the following methods can reduce the risk:
● Do not heat when using.
● Do not use dishwasher or bowl dryer to clean the kettle.
● Don't let the kettle be exposed to direct sunlight.
● Before the first use, wash it with baking soda powder and warm water and dry it naturally at room temperature. ......
Long-term use of mineral water bottles will do harm to the body?
Yes, I seem to remember there is a substance in the plastic bottle, but I can't remember anything exactly. Long-term use will have a bad effect on my health.
Is the crushed mineral water bottle poisonous?
This material can be crushed and is not toxic. Plastic bottles are mainly made of polyethylene or polypropylene and contain a variety of organic solvents. Most beverage bottles are made of plastic. Polyethylene and polypropylene are nontoxic and tasteless, so it is safe for people to fill drinks. However, once polyethylene is corroded by high temperature or acid, it will slowly dissolve and release organic solvents, which is harmful to human body. It has been reported that long-term consumption of food contaminated by polyethylene molecules will cause dizziness, headache, nausea, loss of appetite, memory loss and even anemia. Therefore, using vinegar in plastic bottles is harmful to human health. Therefore, glassware should be used instead of plastic products to hold spices and the like in the family. When using plastic products, we should pay special attention to avoid contact with vinegar, detergent, etc. And avoid direct sunlight and high temperature to avoid chemical reaction. In addition, when buying plastic tableware, you should choose plastic products with PE (polyethylene) or PP (polypropylene) labels, few decorative patterns, colorless and tasteless, and smooth surfaces. There are many ways to make polyethylene, and the most common one is to polymerize ethylene at 200 ~ 300℃ and 1000 ~ 2000 atmospheric pressure. In polyethylene, no other substances are doped. The polyethylene prepared by this method has low density, soft texture and high stability to sunlight, air, moisture and chemical reagents, so there is no need to add stabilizers and plasticizers, which are mostly toxic or highly toxic.
